Holiday gift guide for sustainable coffee lovers

In case you don’t come across enough holiday gift guides this season, I’m highlighting some of my favorite items, many of which you can find year-round in the Coffee & Conservation store.

The two best coffee books are Uncommon Grounds The History Of Coffee And How It Transformed Our World and God in a Cup: The Obsessive Quest for the Perfect Coffee. Here is my review of God in a Cup.

Another book I have not yet read is Ivette’s Natures Matrix: Linking Agriculture, Conservation and Food Sovereignty, which includes a chapter discussing coffee. Authors Ivette Perfecto and John Vandermeer are University of Michigan professors who have done so much of the pioneering work on biodiversity and shade coffee. More on this book here.

Three excellent low-tech coffee brewing devices are the Chemex Classic Glass Coffee Maker; the AeroPress Coffee and Espresso Maker, which is excellent for travel; and my favorite press pot, the Planetary Design Table Top Stainless Steel French Press. I reviewed its smaller cousin the travel French Press mug, and the same praise applies to the larger models.

I also like to recommend gold coffee filters to reduce the use of paper filters.

I’m pretty blown away by the remarkable art of Andrew Saur and Angel Sarkela-Saur, who use coffee to produce stunning watercolors. Take a look at their gallery at Coffee Art; prints start at only $10.

Earlier this year I screened the three-part documentary Black Coffee. It was extremely well done and traces the impact of coffee through history. Readers may also be interested in the story of Ethiopian coffee in the well-known powerful film Black Gold.

Finally, if you’d like to spread cheer directly to coffee-growing communities, please consider a donation to the Cafe Femenino Foundation, Grounds for Health, or Kiva micro-loans to coffee farmers. This is really what holiday giving is all about.

Refilling K-cups, take 2: The My-Kap reusable lid

One of the most popular posts on this site is the one I did on refilling K-Cups, the single-serve coffee “pods” used in Keurig brewers. I outlined a method for re-using K-Cups by using plastic wrap. It works, but the amount of time it takes to clean out a used K-Cup and then cut and properly apply the plastic wrap really defeats the purpose of the whole Keurig system, which is speed and convenience.

Later, I reviewed the Keurig My K-Cup Reusable Coffee Filter, a product designed for the Keurig brewers that avoids the use of the K-Cups altogether by allowing you to use your own freshly ground coffee in the brewer. (Update: see also this post on the Solofill reusable coffee filter.)

Now along comes another product that allows you to re-use K-Cups with your own ground coffee: the My-Kap. It’s pretty simple — a plastic cap with slightly beveled edges that fits snugly in the top of a used K-Cup, once you’ve removed the foil, cleaned out the filter, and refilled the cup with ground coffee. It already has a hole in the center for the Keurig brewer’s piercer/water dispenser.

The main thing you need to do differently when using a used K-Cup topped with a My-Kap is hold down the handle of the Keurig brewer while the coffee is being brewed. This allows a snug fit. It will work if you don’t, but you will get leakage within the brewing “basket” (K-Cup holder assembly) which will spray and/or drip from not only the exit hole, but also the seams of the basket, depending on your brewer and its structural integrity. Even holding down the handle, using the My-Kap is slightly drippy. You may have to clean your brewer more often.

That being said, the My-Kap works like charm, as advertised. Some thoughts:

Pros:

  • Putting the My-Kap on the used K-Cup is, without a doubt, much faster and easier than fiddling with plastic wrap.
  • Both when refilling a K-Cup using plastic wrap, and when using the My K-Cup Reusable Filter, I had a hard time getting the proper grind and filling the K-Cup or filter with the right amount of grounds. The brewer forces water through the K-Cups under pressure, and the K-Cups are designed and filled so they won’t create problems (overflow, blowouts, etc.). The My-Kap fits tightly enough to circumvent most of these problems. The instructions say to fill to 3/4 full, but it seemed quite forgiving through variations in grind size and amount of coffee used, taking the guess work out of reusing a K-Cup.
  • You don’t have to remove the K-Cup holder assembly from your Keurig brewer, as you do with the My K-Cup Reusable Filter.
  • The cap is stiff and sturdy, and can be washed (dishwasher safe) and used indefinitely.

Cons:

  • Be careful prying the cap off after you brew a cup of coffee with a My-Kapped K-Cup. An odd little plastic tool is provided. I’m not sure if it was actually made for this application, because it looks a bit like some sort of peg board hanger. No matter which way you use it (I believe it is meant to be used as shown on the right), the My-Kap is snug and unless you are very careful, it will pop off suddenly, and soggy ground coffee will fly everywhere. Do it over a sink or wastebasket.
  • Although I have heard of people doing so, I wouldn’t recommend preparing many refilled K-Cups using My-Kaps ahead of time. There is a hole in the center of the My-Kap itself (nearly as large as the diameter of a pencil), and coffee will spill out of it if it falls over. There are also one or more holes in the bottom of the K-Cup from the brewing process. Ground coffee gets stale fast enough, and all these holes will just speed that process along.
  • The usual caveats of reusing K-Cups apply. The inner paper filter can’t be completely cleaned of coffee grounds and oils, and in addition to trapping flavors will also eventually become clogged. Nor can coffee oils be cleaned from the inner sealed space between the bottom of the filter and the bottom of the K-Cup. Frankly, I also wonder how often the plastic K-Cups should be exposed to high heat.
  • My-Kap is made of polycarbonate plastic, and as such may contain BPA. If you are concerned about possible exposure to this chemical, this product might not be for you.

When I wrote my first post in May 2007, Green Mountain Coffee Roasters (which purchased Keurig in 2006) was working on more sustainable or recyclable materials for use in the K-Cups. They are still working on this (here is a June 2008 post from the Green Mountain blog on the topic), as they are facing the challenge of finding materials than can withstand heat and pressure, as well as protect the coffee from light, heat, moisture, and oxygen while being stored. I was recently told by a Green Mountain rep that they have “had some promising results in this area and hope to be selling a tea product in a K-Cup made from renewable materials in the first part of 2010 and portion packs with more substantive improvements in the not too distant future.”  Keurig has an environmental policy on its web site, where it explains the construction of the K-Cup in more detail, and other actions the company is taking to reduce environmental impact.

The My-Kap comes with three caps, a removal tool, and/or a brush to clean out the K-Cup.

Not-quite-coffee review: Finca Mauritania Cascara

Just to end the year on a unique note, we decided to try an interesting and unique coffee product, cascara. This is dried coffee cherry, and can be prepared as an infusion like tea.

Something old is new again
Although unfamiliar to most Westerners, this is an ancient beverage in Yemen — it may have even pre-dated the actual roasting and brewing of coffee beans. There, and in a few other countries where it is prepared, it’s known as qishar (or qishr, quishar, quishr, keshir, etc.). In Yemen qishar is often made with ginger, sugar, and cinnamon (although many recipes you’ll find will substitute the coffee “husks” with ground coffee).

Enter Aida Batlle!
If anybody in the New World was going to produce and market qishar to the specialty coffee world, it was going to be Aida Batlle, proprietor of three outstanding El Salvador coffee farms — Los Alpes, Finca Kilimanjaro, and Finca Mauritania. She’s committed to quality, sustainability, and innovation.

Coffee is rarely dry processed in Central America due to the damp climate which is so much in contrast with the arid origins of most dry processed beans. But Aida has been experimenting with both dry process and pulped naturals for some time. For her dry process coffee, which she calls “pasa” (“raisin” in Spanish), she leaves the cherries on the tree after they ripen until they dry out and look like raisins. The beans are hulled from the cherries. Normally coffee pulp and skins — from either wet or dry processing — are composted and used for fertilizer. In this case, the dried cherry is used for cascara.

Aida produced around 225 pounds of cascara from her Finca Mauritania harvest. I obtained my cascara from James Hoffman‘s Square Mile Coffee Roasters in the UK, and from Counter Culture Coffee. Square Mile is sold out for the year; I don’t think Counter Culture offered it for sale but used it at tastings and as gifts.

During a visit to Yemen last year, Thom Owen of Sweet Maria’s took a photo of some qishar. It appeared not very uniform, with hunks of hulls and crusty pulp, and it looked dry and flaky. The Finca Mauritania cascara looks much like tree bark, was a rich reddish-brown color, and had a pliable texture.

This bark-like appearance no doubt gave this product its name, as “cascara” refers to tree bark in Spanish. This coffee cascara should not be confused with cascara sagrada, the dried bark of the California buckthorn tree, Rhamnus purshiana. Nearly all Rhamnus have phytochemicals that act as laxatives, and Rhamnus purshiana has long been used as an herbal laxative. Be forewarned that at least in North America, if you Google “cascara” you get lots of hits on the constipation cure, not the coffee tea!

Preparation and taste
The aroma of the raw cascara is powerful and intoxicating. Nearly every person who stuck their nose in the bag said “Wow!” Two descriptions for the smell of the raw cascara came up frequently: raisins and pipe tobacco. The latter aroma sent me back 40 years to sitting on my grandfather’s lap as he smoked a fragrant pipe. Both my husband and I, the only ones from our tasting group that had ever been near coffee mills at harvest time, also recognized the familiar sweet smell of slightly fermented coffee pulp. Licorice came up a couple times, and others detected wine, apple chips, or dried cherries. A few of us tried just chewing on a pinch of the stuff. I thought it was quite good, and the flavor lasted until the chips were well masticated. (This might be the non-liquid solution to a caffeine fix in the field. Bonus: fiber!)

Cascara is brewed like tea. No additional prep is needed — just use the cascara straight from the package. Square Mile recommends a ratio of 20 to 25 grams per liter of water and a 4-minute steep time. Sweet Maria’s advised using the same proportions as brewing coffee, with a steeping time of 4 to 12 minutes, with 8 to 10 minutes being best. Experiment! Your mileage may vary.

Upon brewing, the first thing you’ll notice is that the aroma of the beverage is not like the aroma of the raw material. It has a sort of vaguely grassy smell. One person thought it smelled like wet dog. Nor does it taste like it smells. With lesser quantities or shorter steep times, it is very lightly sweet; all flavors intensify if more cascara is used or it steeps longer.

The first, hottest sip has a citrusy tang; several people said it was orange-toned. Overall, the flavor is somewhat rustic or earthy. It reminded two people of rooibos (except cascara does have caffeine). Rose petal or rose hip tea was also mentioned more than once. If you’ve ever tasted a ripe coffee cherry, that mild sweetness was, as you might expect, there as well. Everybody could find some sort of grassy, green vegetative taste. For me, it was celery. One person said it was like sweetened water from a can of bean sprouts or bamboo shoots!  A couple of us thought it had a sort of odd, syrupy aftertaste (it reminded me of sticky coffee pulp). After it had steeped to the color of strong coffee, one person thought it was robust enough to remind them of beef bouillon.

There was some experimentation with milk or sugar, but nobody said additives made a huge difference in how they felt about it. Some people took to the cascara right away, especially if they were regular drinkers of herbal teas. I prefer refined black teas such as darjeelings, but I liked the cascara better after drinking it a few times, so it may be an acquired taste for some people. Everyone was anxious to try it and glad they did, even if they weren’t coffee drinkers — it was just that singular an experience. If you have an opportunity to try some, let me know what you tasted and how you liked it!

And with this last review, I’ll close out 2008. Happy New Year to all C&C readers!

Book review: God in a Cup, The Obsessive Quest for the Perfect Coffee

Journalist Michaele Weissman has put together a great overview of the world of specialty coffee in God in a Cup. She traveled around the world with coffee buyers and explored the contrast between mass-produced, commodity coffee and artisan-focused, quality-oriented specialty coffee.

This book isn’t really about searching for great tasting coffee, but uses that pursuit to frame the genesis and impact of specialty coffee for consumers and especially producers. While not strictly about coffee sustainability, it nonetheless brings alive many of the points that I strive to make here at Coffee & Conservation on the topic and the crucial role specialty coffee roasters make in this arena — and in turn how consumers can support it. As such, it lays the foundation for much of what I discuss here.

Weissman preserves her artfully-paced narrative by placing the in-depth background information at the back of the book or in boxes, but still provides enough detail in the main text to clearly explain to readers unfamiliar with the coffee trade and the stakes involved.

She does a great job of highlighting the passion — and activism — of the pioneers in this industry. Much of the focus is on her travels and interviews with three of them: Counter Culture’s Peter Giuliano, Intelligentsia’s Geoff Watts, and Stumptown’s Duane Sorenson, but many others are mentioned. This personal touch lends authenticity. It also keeps readers connected, as following these coffee buyers provides an opportunity to really understand the complexities involved in producing this crop and bringing it to market. Most revealing for me were the discussions about Fair Trade, and in particular the examination of the cooperative system. The example of the troubles Watts has had with poorly run organizations helps to illustrate that cooperatives (which are the only producers allowed to be certified Fair Trade) are not always the best way to protect farmers.

I approached this book with a little trepidation, as I have read way too many articles about coffee that were superficial, not factual, lacked a fresh approach, or were just examples of lazy reporting. This was none of these. If you are at all interested in coffee (which you must be if you have read this far), I highly recommend this book. Further, get a couple extra copies for your coffee-loving friends, people you would like to convert to specialty coffee, or those in your life that don’t really “get it.” God in a Cup will make a great gift this holiday season.

To get a sense of what this book covers and Weissman’s take on it, read this interview with her at Salon. She also maintains a blog which explores her ongoing coffee experiences. Then go pick up a copy of her book!

Book review: Starbucked

I’ve just finished Starbucked: A Double Tall Tale of Caffeine, Commerce, and Culture by Taylor Clark, just released by Little Brown. It’s an entertaining, well-written and researched “biography” of the genesis and rise of Starbucks, and the concurrent/coincident specialty coffee scene in the U.S. Anyone interested in Starbucks (love, hate, or neutral) or the genius of retail marketing will really get into this book. Those intrigued with American culture will also find ponderable material here, and it will be valuable for readers who want to understand the post-1970s history of coffee in the U.S. (for the most thorough overall history of coffee, you can do no better than Mark Pendergrast’s Uncommon Grounds).

Clark leaves few stones unturned, especially when discussing the evolution of the Starbucks marketing strategy. The one thing that was barely discussed was sustainability. The closest is an entire chapter on Fair Trade which correctly points out that low-quality robusta coffee is the enemy of struggling coffee farmers, whose

“…fortunes rise and fall on the world’s demand for good coffee beans, and no one has done more to generate an insatiable global thirst for high-quality coffee than Starbucks.”

We can quibble about the quality of Starbucks beans, but the distinction here is between the quality of the big grocery store brands versus Starbucks. While exploding the myth that Starbucks harms independent coffee houses, Clark makes a point I have made here several times: that Starbucks has drawn out people who never strayed from Folgers, and these converts go on to explore other coffee venues.  And with any sort of luck, these converts don’t turn back to grocery store brands. Clark also echoes one of my mantras:

Helping lift farmers from poverty, then, isn’t so much a matter of hectoring companies like Starbucks (even if the company isn’t the human rights champion it claims to be) as it is of making sure people never drink the cheap and exploitive coffee offered by conglomerates like the Big Four.

Not only lifting farmers from poverty, but also preserving biodiversity.

Starbucked will help readers understand why we owe Starbucks quite a bit of credit for transforming coffee culture and triggering a chain of events that is helping consumers realize their own transformative power via the choices they make for their daily cup.

Keurig reusable coffee filter for single cup brewers

Some time ago, I wrote a post on refilling K-Cups, the single-serve coffee “pods” used with the Keurig single-cup coffee brewers.  I hate the idea of sending the plastic, foil-topped cups to the landfill.  An internal memo provided to me by a representative of Green Mountain Coffee Roasters, which owns a large share of Keurig Corp. and manufactures K-Cups, stated “the environmental impact of the K-Cup waste stream is one of the most significant environmental challenges we face.”

The company does offer a product which completely avoids the throw-away K-Cups: the Keurig My K-Cup Reusable Coffee Filter. Let’s take a look at this product.  (Update: this review refers to the older version, but the concept is the same. I’ve since written a table of K-Cup alternative products, with links to all my reviews, updated in December 2018).

What it is
The My K-Cup is a simple three-part contraption: a mini gold filter basket that fits into a filter holder with a lid. The filter holder corresponds with the removable assembly in the Keurig brewers that hold the disposable K-Cups. I thought perhaps it would be difficult or annoying to swap out this assembly for the My K-Cup, but either pops right out and the other pops right in. Simple.

How it works
Very straightforward. 1) Fill the filter basket with ground coffee. 2) Set it in the bottom holder, twist on the lid. 3) Pop out the assembly in your Keurig brewer, and pop in this holder assembly. 4) Push the brew button.

The math
There is, of course, a bit of finesse involved in step 1 above.

First, a standard measure for coffee is 2 tablespoons per 6-ounce cup of coffee. Since “tablespoons” (and coffee scoops) vary, we’ll go with the equivalent recommended by the Specialty Coffee Association of America, 10 grams per 6 oz cup. I realize I’m mixing metric with English measurements. Most people have kitchen scales, which are able to measure weight in grams. And most average-sized coffee mugs are between 6 and 8 ounces. Once you know what 10 grams looks like, and how much water you typically use, you’ll know how to make your coffee.

So, the package insert says that the My K-Cup holds 2.7 tablespoons of coffee. I won’t use a conversion formula to tell you what the equivalent is in grams, since I’ve not found one with the proper translation of volume to weight for coffee. I simply used my scale, and the My K-Cup holds right around 14.5 to 16 grams of coffee.

Usage tips
The instructions say not to pack the My K-Cup filter. The water would not flow through the coffee, grounds would overflow into the holder, and they would clog the hole at the bottom of the holder. Likewise, very fresh coffee (which I hope you are using) “blooms” as the hot water causes a release of carbon dioxide. That can also cause overflow and cloggage.

So use care to only fill the filter to just under the plastic rim. Actually, probably the worst aspect of the whole My K-Cup experience is filling this little filter with coffee grounds. It’s easiest with a spoon, but still sort of a pain.

A very fine espresso grind may clog the filter and cause the same problem. I experienced this because I thought I would get more flavor from a very fine grind, and it made a mess. It will require some care to find the correct grind that will allow enough extraction but not cause clogging or overflow.This probably varies with the coffee and roast strength, not to mention the grinder. Start with a grind somewhat finer than a drip grind. Go with as fine a grind as possible that doesn’t cause brew failure.

Results

Compared to a drip machine, the Keurig provides a slightly cooler brew temperature (the max is 192F) and a shorter length of time the grounds are in contact with the water. Therefore, the 15 grams of coffee in the My K-Cup would work best with smaller brew sizes (under the large 9 ounce choice offered on the brewers).I did some tests, using the same coffee and same grind with the My K-Cup, a drip brewer, and the Aeropress small batch coffee maker. Not surprisingly, the Aeropress offered the most rich and intense flavor. But the My K-Cup does make a cup quite comparable to a typical drip machine.

And if you are so pressed for time that you are using a Keurig brewer in the first place, my bet is that you neglected to clean your old drip machine on a regular basis. This is a huge, overlooked advantage of a Keurig brewer: it doesn’t get dirty. You will certainly want to wash the My K-Cup filter and holder (or the assembly for the disposable K-cups) with soapy water on a regular basis, but overall it’s much less work than maintaining a drip machine.

Conclusion
The My K-Cup is the sustainable choice — when used with a sustainable bean, of course — for use with a Keurig brewer. Still, it will probably not satisfy those who want a strong, really flavorful cup (especially a big one). I think Green Mountain has achieved good results with some of their K-Cup  varieties, although I’ve yet to have any K-Cup that compared to a decent bean in a French press preparation. It would probably take a lot of experimentation to get consistent, really satisfying, beyond-the-ordinary coffee using a variety of beans with My K-Cup. This sort of defeats some of the convenience of a Keurig brewer, but still preserves the speed, energy efficiency, and coffee waste minimization advantages of these machines.

Refilling Keurig K-cups

(Update: I have published a summary of all my posts on Reusable alternatives to K-Cups, which includes a detailed table of the features of the Keurig My K-Cup Reusable Coffee Filter, the Ekobrew Refillable Cup for Keurig K-cup Brewers, the Solofill Refillable Cup For Keurig K-Cup Brewers, the My-Kap Kaps for refilling K-Cups, and the EZ-Cup refillable cup for Keurig brewers).

Keurig single-cup coffee brewers are handy for certain applications.  I work in a university building where lots of staff and volunteers have access to the coffee pot.  Certain times of the year, my crew and I spend about 15 minutes of every hour in the building.  If we brew a pot of coffee, someone else inevitably drinks most of it before we get back at the kitchen, or our stints in the field result in coming back to cold or over-cooked coffee. The Keurig is a perfect solution — brew a very quick, fresh single cup when we have our little interludes.

The issue we have is with excess packaging. The used plastic K-Cups are not recyclable.  I wrote to Green Mountain Coffee Roasters, which owns a large share of Keurig Corp. and manufactures K-Cups, regarding plans to make the K-Cups recyclable. They replied:

“We are not satisfied with the current environmental impact of the K-Cup packaging used with the Keurig system.  We have signed an agreement with one of our materials suppliers for the Keurig K-Cup product to jointly fund research on the application of renewable materials for the K-Cup.  One option may be to develop a brewing system that uses a photo-biodegradable K-Cup with a non-metalized lid.”

Bravo to Green Mountain that they are actively pursuing a solution! But then, this company does so much for sustainability, their efforts don’t surprise me.

Reuse is a form of recycling, so I decided to find out if I could refill a used K-Cup with my own coffee successfully.  It’s pretty straightforward — just make sure that the product used to reseal the cup is Glad’s Press and Seal.  This stuff is not like regular plastic wrap, and works like a charm.

Here’s how you do it:

  1. Get all the foil off the rim of your used cup, and make sure the rim is dry before applying the Press and Seal.
  2. Try to rinse as much coffee out of the filter in the cup as possible.  It doesn’t really seem to matter too much whether the coffee is rinsed out when it’s still wet or if it’s dried out.
  3. Grind the coffee very fine — there is not much time for the water to soak the grounds and you need as much surface area exposed as possible.
  4. Fill the cup to about 3-5 mm from the top with ground coffee — you can tap the cup to settle the grounds, but don’t pack it down. I tried it and it created overflow due to the force of the water going through the grounds. This amount of coffee is probably similar to the extra bold K-Cups,which have more coffee in them than the regular K-Cups; I personally find most of the regular ones produce pretty insipid brew.  Likewise, although I prefer light roasts, they come through as weak in the Keurig, so darker roasts are best.  But experiment — your tastes may vary. Overall, I use the Keurig for convenience — it’s not for outstanding coffee, no matter what you use.
  5. Cut two small squares of Press and Seal per K-Cup.  I’ve tried both one and two layers, and two work better.  The squares only need to be large enough to overlap the edge and stick to about 10 mm of the sides of the cups.
  6. Holding a square taut, place it on the top of the K-Cup so it is nice and tight, and press along the rim.  Then seal it along the underside of the rim and the side of the K-Cup.  Repeat with other square.
  7. Viola! Ready to use.  Important: when you place the refilled K-Cup in the brewer, make sure to line up the hole on the bottom with the pin in the brewer.

The limiting factor in the number of times a K-Cup can be refilled is clearly the inner filter. Eventually, it will get too clogged with fine particulates; I suppose it might also rip or get a hole. Mis-aligning the bottom hole (step 7) will also retire a K-Cup.  So far, I have reused a single K-Cup 5 times without any noticeable change in the flavor of the coffee.

Refilling K-Cups in some ways defeats the convenience of the Keurig system, but since I grind coffee daily at home, refilling a couple of cups is no big deal.  Green Mountain also sells a product called My K-Cup, a plastic and mesh filter assembly for ground coffee that is used in place of a K-Cup.

Finally, my spent K-Cups are also repurposed, seeing a new life as filter cups for my pitfall traps, where insects collected in fluid-filled containers inserted flush with the soil must be strained and dried before being examined and identified. K-Cups work perfectly for this, as the bug-containing cup at left shows.  Samples can even be stored in them, as the cups are also easily labeled with a felt tip marker.

I imagine you could also start seeds in the K-Cup (the space between the bottom of the filter and the bottom of the cup could hold some water which would wick up the filter, and the hole in the bottom would provide drainage). Creative types could find other uses for old K-Cups.  Feel free to post them in the comments!
