Coffee review: Doi Chaang Wild Civet Coffee

Plainspoken Coffee. A Coffee Review for Ordinary (or in this case, wealthy) People by Ordinary People, #42.

Introduction to animal-processed coffee
Our previous experience with kopi luwak — coffee beans processed through the digestive system of  civets — was not a pleasant one. You can read the ins and outs of kopi luwak in the original post, but basically the beans are gathered from the poop of a mongoose relative known as a civet cat, usually the Asian Palm Civet (Paradoxurus hermaphroditus). Due to the relative scarcity of civet-processed beans, the labor theoretically involved in gathering the poop, and the substantial novelty factor, kopi luwak demands very high prices and is often billed as the most expensive coffee in the world. Civets are native to southeast Asia, and low quality robusta beans are often a major component of kopi luwak coffee.

In my review, I surmised that it was impossible to determine if kopi luwak coffee was sustainably grown because in order to maintain volume, beans could have been gathered from any type of coffee farm, including sun coffee, especially because so much of it is cheap robusta. I’ve also come to learn another way volume is maintained is to keep civets in captivity and feed them coffee cherries. You can view videos that show civets in cages, then people supposedly harvesting civet dung off the forest floor. Likewise, this web site indicates the civets are raised on a farm. This practice is nothing new, as civets are raised for fur, musk, and food in many areas; these animals are usually caged. I have also heard that civets may be penned in a particular area where they can forage for coffee. So not only do you not know where the beans come from, there may also be animal welfare issues, as farm conditions cannot be verified.

Thai wild civet coffee
Enter Doi Chaang Coffee Company. We have reviewed Thailand’s Doi Chaang coffee before, and in that post I outlined the story behind this innovative partnership (more detail here by Canadian partner John Darch). The driving force behind the success of the Thai coffee venture is Wicha Promyong (left), a former entrepreneur from southern Thailand who “adopted ” the Akha hill tribe families in the Chiang Rai region and helped them organize and improve and market their coffee. Do not be fooled by this humble-looking man in traditional garb — he is no country bumpkin!

Recently, Wicha read about kopi luwak: the outrageous prices, the questionable quality. He asked the Doi Chaang farmers if they had observed civets in their coffee farms and seen their bean-laden scat. Sure enough — civets were present (Asian Palm Civet and Masked Palm Civet, Paguma larvata), and leaving their potentially-precious nuggets on the ground. Wicha recognized two important aspects of this situation: the civets were wild, and they were consuming all-organic, all-arabica coffee (caturra, catimor, and catuai varieties). He approached the Canadian partners, who were initially reluctant to roast the coffee and get on the bandwagon. However, they went ahead and invited various VIPs to taste the coffee — and the comments were very positive. And so here we are, another country heard from in the animal-processed coffee arena.

Perhaps one of the most interesting aspects of the Doi Chaang Wild Civet coffee is that it will be sorted into two types: digested and regurgitated. It’s not unusual for animals or birds to immediately regurgitate large seeds from fruit they have just eaten rather than have all the bulk pass through their systems before they can continue to feed.

It is the digestive process of the civet that supposedly creates the unique flavor profile of kopi luwak and similar coffees. Since the regurgitated beans will not have gone through the digestive process or been exposed to digestive enzymes for any appreciable amount of time, it’s hard to imagine that the regurgitated type will have any detectable flavor difference than normally (by humans) harvested and processed beans. Of note, however, is that the “spit” coffee has traditionally been tossed in with the defecated type by kopi luwak purveyors, functionally acting as filler.

Doi Chaang will not mix the two types. This was originally described to me by Doi Chaang as “separated between the spit and swallow.” And I have decided to include those terms here as it will undoubtedly bring all sorts of new readers to Coffee & Conservation. But I digress.

The Review
Now to the $64,000 $500/pound question: how does it taste?

First, the beans were beautiful, of uniform size and shape, without pieces or defects, unlike the hodge-podge we saw in our sampling of kopi luwak. Doi Chaang’s roaster Shawn McDonald used a light hand with these beans and the fragrance was similar to the Doi Chaang peaberry, which we tried beforehand for comparison.

Our group — nearly all of whom suffered through the kopi luwak tasting — were unanimous: we really liked this coffee. It was sweet with a light chocolate or caramel flavor. Nearly every person commented on the civet coffee’s medium body, which was very rich, smooth, even creamy, a sensation that increased as the cup cooled. “Smooth chocolate” and “honey syrup” were also mentioned. The coffee was well-balanced, and just really pleasant.

Whereas the peaberry and the standard medium roast we reviewed previously did have the distinctive, though muted, Sumatran-like profile of earth and leather, the civet coffee did not. In fact, I would have been hard pressed to guess the
origin of this coffee, and I surely would not have thought it came from the same dark place as kopi luwak.

In the past, I have tried beans from a single farm that were processed in different ways (washed, semi-washed, natural). I found the degree of difference in flavor between washed and semi-washed from that experience to have been greater than the difference between the washed Doi Chaang peaberry and their civet-processed beans. Clearly, there was some difference in the civet coffee, but it was subtle, maybe more in line with the difference in flavors between microlots grown on the same farm.

Everyone who tried both Doi Chaang coffees liked the civet coffee better, hands down, and overwhelmingly agreed the civet coffee was better than the kopi luwak. Since that’s not saying much, note that the final rating of 3.75 motmots (several people gave it 4 motmots) is at the upper range of our usual coffee ratings. Is it worth $500 a pound? It was very good coffee, and I wouldn’t complain if I had paid $25 or so a pound for it. But personally, I don’t expect to ever have a coffee, beverage, or any food item that is worth that price based on flavor alone. But I will say without reservation: for those who feel compelled or interested in having an animal-processed coffee and are willing to pay for the rarity and novelty, this is it.

The Wild Civet coffee will be marketed starting in June at Urban Fare markets in Vancouver, BC, in Pusateri’s in Toronto, and on the Doi Chaang web site. I wasn’t fooling about the approximate price. The annual gathering of the Doi Chaang Wild Civet coffee is not expected to exceed 100 kilos, with only 40 being available this year. Since the only way to increase production without farming the civets is to increase natural habitat, Doi Chaang plans to step up reforestation efforts in the region of the farms. A final, nice, sustainable touch.

Update: Ken Davids at Coffee Review has just written about this coffee.

Caffeine-free coffee species one of top 10 new species in 2008

A species of naturally caffeine-free coffee from the Cameroon, Coffea charrieriana, has been named one of the top ten new species described in 2009 by the International Institute for Species Exploration (IISE) at Arizona State University.

The coffee was actually collected in 1983. Cuttings were cultivated in a research collection and remained unstudied by taxonomists until 1997. It wasn’t until last year that a description of it as a newly described species was published. The original cuttings from the plants were collected in wet, primary rainforest on a steep, rocky slope in the Bakossi Forest Reserve, Tombel Division, Southwest Province, Cameroon, at an elevation of 160 m. It is one of only a few species of caffeine-free Coffeas, and the first from Central Africa.

The top ten species from the previous year are announced by the IISE along with the release of the annual State of Species report, which discusses the status of our knowledge of earth’s species and summarizes the number of species newly described in the most recent year for which complete data are available. The 2009 report discusses the over 18,000 new species discovered in 2007. The report is produced in partnership with the International Commission on Zoological Nomenclature, the International Plant Names Index, Thomson Reuters (publisher of Zoological Record) and the International Journal of Systematic and Evolutionary Microbiology.

My mug is on In My Mug

One of the best things to happen at the the Specialty Coffee Association of America expo in Atlanta this year was meeting coffee people I had only corresponded with up to that time. Surely one of the highlights was getting to meet and talk to Steve Leighton of Has Bean Coffee in the U.K. I’ve been a secret fan of Steve’s for a long time. In addition to sourcing great coffees, he has excellent descriptions on his web site, travels frequently to origin and blogs about his experiences and other coffee news, and through his strong online presence really conveys his passion for coffee. Every roaster should aspire to communicate to consumers about coffee the way Steve does.

One of Steve’s gigs is In My Mug, a weekly video in which he describes a particular coffee he offers. Somewhere along the line people started sending him mugs to use in the videos. When I got home from Atlanta the first thing I did was send Steve a mug. Since Coffee & Conservation doesn’t have a mug, I sent him the simple but stylish Rouge River Bird Observatory mug from my real job.

This week Steve used the mug to review his Guatemala San Rafael Pacun, a 2008 Cup of Excellence winner. I should say that the second thing I did, once I packed the mug and sent it overseas, was place an order from Steve. Shipping is a bit pricey from the U.K. to the U.S., but I got my coffee just five days after ordering/roasting. Although I didn’t order the Guatemala, the coffees I got were excellent — especially the Bolivia Machacamarca, which Irish barista champion Colin Harmon served us in a cappuccino while he was practicing for the WBC finals.

Thanks, Steve, for the C&C shout out, and for your fantastic coffee!

When birders drink Folgers, part 2

(Part 1 here)

Last Saturday was International Migratory Bird Day. This annual event coincides with the peak of spring migration and is intended to increase awareness of birds and their conservation throughout the Western Hemisphere. Lots of organizations, parks, and refuges have birding events. I was reading about one of these celebrations (I later heard 15,000 people showed up) and the author made this comment on a picture of a throng of birders lined up on the trail: “There is tens of thousands of dollars of camera hardware in this photo, and the total value of optics and camera equipment on the trail would be utterly staggering if it could be tallied.”

I immediately wondered how many of these affluent people spent a few extra bucks to make sure that the coffee they drank supported the birds they were photographing, watching, and enjoying so much.

Probably not that many; I’ve written before about how resistant birders can be to changing their coffee-buying habits. The top reasons I’ve heard over and over are that shade-grown/sustainably-grown coffee is too expensive, or too inconvenient (certified shade coffee, in large part due to lack of demand, can be hard to find). The latter is really related to the former. I can’t imagine anything more easy than ordering coffee online to be delivered to my door, and there is plenty of sustainable coffee available this way. But this adds shipping to the cost, so it again comes down to price.

For the most part, this is a flimsy excuse coming from most active birders. Here are some facts:

  • A 1991 profile [1] of American Birding Association members showed that 46% of members responding to the survey had incomes over $50,000.
  • The same study showed that ABA members spent $3,374 annually on birding, with 74% of that total going toward travel to see birds, and 17% on equipment.
  • Around the same time, a survey of active birders [2] in the general public showed 16% had incomes greater than $50,000 (at a time when the average U.S. income was $20,000).
  • That study provided an annual expenditure per birder of $1,852, of which 71% was travel related.
  • A more recent survey by the U.S. Fish and Wildlife Service [3] found that 27% of people who lived in households earning greater than $75,000 identified themselves as bird watchers.

I’ve already pointed out that great, sustainably-grown coffee doesn’t actually cost that much on a per cup basis. How about on an annual basis, to put the expense in line with the figures above?

While your mileage may vary, a pound of coffee generally yields about 40 to 45 eight-ounce cups of coffee. If you drink two cups a day, you go through 18 to 20 pounds of coffee a year. If you buy cheap, unsustainable supermarket coffee you probably pay between $5 and $7 a pound. I’m asking you to buy tasty, sustainably-grown coffee from a smaller specialty roaster, at around $10 to $13 a pound, or somewhere around $100 to $150 more a year.

Another report [4] described birders as “… the major, perhaps only, user-group of neotropical migratory birds.” Many of the active birders I know wouldn’t blink an eye at gassing up the car and taking off to see a rare bird hundreds of miles away, and many I know do this several times a year. But they are unwilling to spend the money to make sure those birds are around in years to come. Maybe the goal is to make all birds rare. If so, by drinking cheap coffee, they are doing a good job.

Research: Coffee as an invasive plant in India

Brewing trouble: coffee invasion in relation to edges and forest structure in tropical rainforest fragments of the Western Ghats, India. A. A. Joshi, D. Mudappa, and T. R. Shankar Raman. 2009. Biological Invasions 11:2387-2400.

While invasive plant species receive a lot of attention, the focus is often on weed species that compete with crops — not the potential invasiveness of the crops themselves. Coffee is native to Africa, but of course is widely planted in tropical regions worldwide. Both varieties of coffee, Coffea arabica and C. canephora (commonly called robusta) are grown in India.  In the Western Ghats of India, a biodiversity hotspot, coffee is often planted adjacent to fragmented forest reserves. This study looked at the spread of coffee into forest fragments at four sites that adjoined coffee farms, but varied in degree of disturbance.

Both coffee species were found in all the forest fragments, with whatever species that was cultivated in the adjacent farms being the most abundant. Stem density generally decreased as the distance from the the plantation edge increased for the coffee species planted in the adjacent farms. Stem density of arabica increased with disturbance level of the fragment. Robusta did not show such a pattern, and stem density was many times higher than arabica in fragments adjoining robusta farms, including the least disturbed, protected forest fragment. Further, there was a negative relationship between robusta invasion and native shrub density.

The main consumers and dispersers of coffee in India are the Asian Elephant, Lion-tailed Macaque (Macaca silenus), Sloth Bear (Melursus ursinus), and Brown Palm Civet (Paradoxurus jerdoni). Yet in this study the pattern of dispersal in one fragment, which was separated from the farm by a stream, and the sharp decline of coffee densities beyond 100 meters hints that small mammals might be important agents for dispersal in these systems. Larger mammals have bigger ranges, and the stream would not have acted as a barrier for them.

The authors concluded robusta may have a greater impact as an invasive species than arabica in this region. Whether this has to do with robusta being more adaptable, or just more fecund (robusta coffee plants can produce four times more fruits than arabica plants) needs further study.

I’ve not seen any similar research on the spread of coffee into forest fragments in Latin America. This may be because of a more limited number of potential animal dispersers, and, at least in many parts of Central America, less cultivation of robusta coffee.

You can find a summary of the paper at the Nature Conservation Foundation web site.

Coffee, climate change, and Rainforest Alliance

At the Specialty Coffee Association of America expo, we attended a lecture on climate change and coffee. Several speakers discussed this topic, but I’ll focus on the climate module that Rainforest Alliance is adding to its certification. This was announced at last year’s SCAA meeting (my post here), and RA’s Jeff Hayward provided more details on the program.

Coffee, especially shade coffee, is a global crop that has a relatively lower impact on greenhouse gas emissions and a more positive impact on carbon sequestration than many other crops.There is potential for shade coffee farms to contribute to the mitigation of climate change and generate income for farmers at the same time; I have a previous post that outlines the basics.

Rainforest Alliance has developed around 100 different criteria used to certify farms. A small number are considered required critical standards. Beyond that, certification is awarded once a particular percentage of the remaining criteria are met. RA is evaluating which criteria represent practices that improve carbon storage and mitigate climate change. If those particular criteria are among those that are met by a farm, they would be eligible to receive a ”Rainforest Alliance Plus” or "Climate Friendly" certification. RA is currently testing some assumptions and developing these criteria in Guatemala.

This will help buyers choose coffee that is climate friendly, but depending on what consumers are willing to pay won’t necessarily generate additional income for producers. A second part of RA’s climate program is to work to develop a mechanism for producers to receive payments for carbon credits within existing carbon markets. Since these must be beyond ”business as usual,” existing shade coffee farms might not be able to greatly increase their amount of carbon sequestration. But this holds promise for farms that are growing sun coffee or shade monoculture as they can gain credits for planting shade trees or for reforestation — the more the better. It could also help discourage the conversion of coffee to pasture or less eco-friendly crops. RA is working on pilot carbon credit projects now in Mexico and Nicaragua.
