Flavour profile

This coffee comes from the Sardinal farm, located in West Valley in Costa Rica, has a completely distinct flavour because of the anaerobic fermentation process it undergoes.

Anaerobic fermentation of the coffee cherries results in a complex cup with flavour notes of cinnamon, dark cherry, cacao, rum-raisins, green apple, molasses.

All of our coffees are roasted to order and shipped whole bean to ensure maximum freshness.

The story – the farm

This coffee comes from the Sardinal farm, located in West Valley in Costa Rica. It was created by our dear friend Esteban (whose coffee took us to the stage at the World Brewers Cup in ‘15 & ‘16!). Esteban’s anaerobic fermentation process, used to create this coffee, is intriguing and complex. This year he experimented with a  H1 Centroamericano variety. He let the cherries ferment aerobic for 48 hours and afterwards added mucilage to the whole cherries, and let it ferment anearobic. This mixture was fermented for 17 hours in an airtight tank. He’s been tweaking his method by controlling the drying phase in a drying machine to get a clean, but very expressive cup!

Mathieu Theis made it to the finals of the WBC once more in 2019 with this amazing coffee . We’re super proud that we roasted for his championship run!

And also Agnieszka Rojeska is using this coffee during the World Coffee & Good spirit Championships in Berlin.

    This is literally the best coffee I’ve ever had, and I’m from Los Angeles. We at least THINK we know coffee. It’s omni roast but our preferred method so far has been aeropress. The cinnamon notes are unbelievable and it is so complex without much bitterness at all. We loved it so much in my house that we bought a full kilo and extra for our friend. Definitely give this a shot if you want a flavorful coffee that isn’t heavy or overpowering.
