Blind Assessment:

Deeply sweet, intricately rich. Lavender, banana, brandy, dark chocolate, tamarind in aroma and cup. Round but surprisingly zesty acidity; buoyant, silky mouthfeel. Dark chocolate and lavender, in particular, dominate in the short finish and carry deeply into the rich, gently drying long.


Wahana Estate is located in the classic Lintong growing district of North Sumatra Province near Lake Toba. It is a central mill drawing coffee from a group of local small-holding producers. It produces coffees processed by at least three different methods: natural or dried-in-the-fruit, traditional Sumatra wet-hulled, and fully washed (all soft fruit residue is removed from the beans before drying). This sample is a dried-in-the-fruit natural. It tied for the second-highest rating in a cupping of Sumatra coffees for Coffee Review‘s July 2016 tasting report. Founded by a bassoonist in 2015, Crescendo Coffee is an online shop that offers consumers a variety of coffee beans freshly roasted with the Easyster, a Korean-made roaster. Crescendo donates a portion of its profits to developing clean drinking water in coffee-growing regions of Africa. For more information, visit www.crescendocoffee.co.kr.

The Bottom Line: A lushly sweet, natural-process Sumatra with a discreet hint of sweet ferment and a long, crisply drying finish.
