Description

This is the first time we have seen this unusual coffee, and it all started in Glasgow. It was at the Glasgow Coffee Festival that we met Diana, who had just started importing coffee into the UK from her hometown of Columbia. Diana was originally born in San Roque, near Medellin, and has three brothers who make coffee. There are a lot of great places in this area. The potential of many small producers.

The cherries come from three farms: El Descanso,El Tractor and Villa Sierra. After picking, the ripe fruit is transported to a wet mill called Renacer (which means "new growth" or "revival" in Spanish). Here, the situation is different: the factory has started the "alcohol-lactic acid" process, giving the coffee a unique flavor.

First, leave the whole cherry for 100 hours, during which time the factory will use the temperature to try to promote the growth and fermentation of the yeast. After that, the cherry was desized and started cool fermentation at about 17 °C in order to promote the growth of lactic acid bacteria. It lasted another 70 hours.

For any coffee, yeast growth and lactic acid bacteria are normal (and important) parts of the process. The difference is the control they use to encourage them at different stages, and how to develop a unique flavor.

Such experiments are not entirely unique: this is the first time we have seen lactic acid fermentation from a Sumava plant in Costa Rica. These two batches have a unique quality and will not let you sit on the fence. I hope you will be as excited as I am and try something new.

This unusual lactic acid process produces a unique flavor. Here, I think of liqueur. There is sweet apple juice, light limes and attractive taste, slightly spicy. The body is big and sticky, and it does play a big role in keeping all tastes balanced.
