East Java Ijen Highlands - Anaerobic Natural

We Taste -

Mt. Ijen towers over the world's biggest, most acidic lake. Kawah Ijen lake effervesces a bright turquoise color from volcano-infused sulphuric and hydrochloric acid and minerals. The vented nutrients do more than turn the breathtaking lake acidic; they infuse the local soils with minerals that improve soil fertility, water retention, and aeration, improving coffee harvest yields and cherry quality in East Java, one of the oldest coffee growing regions outside of Ethiopia, Yemen, and India.

Smallholding farmers, often Pandalungan Madurese in heritage, live across the Ijen Highlands, growing fruit, vegetables, and tobacco as well as coffee varieties Typica, Lini S288, S795, Cobra (Colombia Brazil), USDA, and Andungsari. Farmers exchange their fresh harvest with cherry collectors who assess quality. Once purchased and transported to the Bottolingo wet mill, all cherry deliveries are checked for sugar content using a BRIX refractometer. This informs producer Kevenka Coffee in determining the best processing method. For this microlot, Kevenka founders Kenny and Kevin Soewondo anaerobically ferment the whole coffee cherry in airtight tanks for seven days. This modern style imparts a remarkably tropical, boozy fermentation, catalyzed by light-medium roasting to taste like ______, ______, and _______.

At a week off-roast, expect a velvety-syrupy body paired with a complex acidity, accented by citric and acetic elements. As the roast enters its second and third week, look for the brightness to mellow a bit, bringing forth flavors like cardamom and cacao.

Roast: Light-Medium - Sweetest, most flavorful brews in the 10 - 30 day range.
Process: Anaerobic Natural - Whole coffee cherries are sorted and washed, then sealed in tanks without air and anaerobically fermented for seven days. Drying takes 7-10 days before the cherries are packed up and shipped to Driyorejo Dry Mill, where they are hulled and sorted four times, finally being QC'ed and packed for export.
