This coffee is from what would have been the 2020 Daterra Farms Masterpieces auction. The auction format was forgoed in 2020 due to the pandemic so the value on these coffees is unbelievable.
The prices these coffees would get at auction would likely be several multiples of what they are available for this year. For example, the Laurina Double Fermented is the same coffee that gave us Frevo last year and Ruda the year before. Frevo set the record for most expensive coffee ever from Brazil at the time.
Fermentation processes lead to new and unique flavours in coffee and this Catucai is no exception. It works well as espresso or with full immersion brewing methods.
Process: the cherries fermented inside a tank equipped with a valve system that prevents any gas from entering the tank. As the cherries ferment, they release CO2 and, because carbon dioxide is denser than oxygen, it pushes the lighter gas out through the valve. After a few hours, the tank environment becomes completely anaerobic, allowing the perfect conditions for microorganisms to perform enzymatic reactions inside of the beans.
