"We exercise control over which microbes are cultivated for our food."
Indonesian civet coffee (also known as Kopi Luwak) is one of the most expensive types of coffee in the world, selling for more than $1300 per kilogram. The pricing is based on Kopi Luwak's unique fermentation process: a small furry, cat-like animal called the civet devours the coffee fruit and then expels the undigested seeds-the coffee beans-through the digestive system. Coffee beans previously fermented in their digestive tract. Over the past year, biologist Camille de Lebeck (Camille Delebecque) and flavor chemist Sophie Deher (Sophie Deterre) have spent a lot of time trying to replicate the civet's ability to change the flavor of coffee without involving civets and their droppings.
Dillerbeck and Dediher co-founded Afineur in New York in late 2014. What they did was a synthetic ecology experiment that used a highly controlled trial and error process to function beyond the microbes found in the civets' intestines. Unlike Kopi Luwak, "we have control over which microbes we cultivate for use in our food," Dillerbeck said.
Use bacterial chemistry instead of cat shit to make more delicious coffee.
Cat poop coffee beans fermented by the civets' gastrointestinal system sell for more than $1300 per kilogram, while those grown in the laboratory by Afineur sell for about $150 per kilogram.
Afineur selected two types of coffee beans from Colombia and Tanzania, and then selected the bacteria for fermentation from a microbial bank containing about 700 species of bacteria and fungi, which are usually absent in the world's few naturally fermented coffee beans. The company mixes hundreds of pounds of unroasted coffee beans with what Dellebeck calls an "ultra-small" mixture of microbes and places them in a metal fermentor for a day or two. In the meantime, these microbes will erode the surface of coffee beans and change their flavor. Subsequent baking removes any remaining microbes from the coffee beans.
The two co-founders say they have identified strains that perform specific functions. For example, some microbes "eat" chemicals that make roasted coffee beans taste bitter and astringent. Other bacteria degrade sugar, protein and even caffeine to achieve the effect of biological decaffeination. Afineur-baked Tanzanian coffee doesn't taste exactly the same as authentic Kopi Luwak, but Delebeck says it was intentional. Silky, fruity coffee roasted by Afineur has a low acid content, making it possible to make people's stomachs feel more comfortable. Producing coffee beans in this way rather than using civets also means that problems such as caging or forced feeding are not involved.
As the company's only two full-time employees, de Lebeck and de Dehe first met when they were in high school on the outskirts of Paris. De Dehe worked as a flavor chemist at confectionery maker Mars. Dillerbeck became a caffeine-obsessed medical researcher at Harvard. When Dillerbeck fell in love with various coffee experiments, de Deher became his preferred partner.
They started the company with $60, 000 in venture capital funding from IndieBio, a venture capital firm that focuses on start-ups. Afineur generated about $100000 in revenue in 2015, mainly by selling coffee beans at several retail stores and on the Kickstarter website, selling coffee beans for $29 per 5 ounces or $129 per 30 ounces, they said. The price is cheaper than Kopi Luwak, which is close to the monthly cost of going to Starbucks for a latte every day, but higher than the price of most Starbucks retail beans. Dan Dan Belliveau, former director of technical services at Starbucks, said Afineur's pricing makes its coffee a fairly niche market. "but if it sells well, it's a free market," Bellevue said. "they're doing really well. Belivo is currently the CEO of startup CF Global Holdings. CF Global Holdings is a manufacturer that uses coffee by-products to produce high fiber powder.
Dullebeck says he and Deh are working on ways to ferment grain. For now, they will launch a global ordering service for coffee beans (10 ounces of coffee beans worth $49 a month, or year-round coffee beans at a discount). In addition, they are in talks with whole Foods (Whole Foods) and high-end restaurants in the New York area to sell Afineur beans through their stores. Dullebeck says he is not worried about the limitations of the company's target audience: "consumers are looking for interesting tastes. The fermentation process unlocks new elements. "
