Anaerobic Robusta Coffee: A Buyer’s Guide to Anaerobic Fermentation
Anaerobic robusta coffee is robusta fermented in sealed, oxygen-limited vessels before drying, so that yeasts and lactic acid bacteria, rather than oxygen-breathing microbes, shape the cup. Done well, it adds tropical fruit, wine-like acidity and a creamy body to robusta's chocolate base. Done badly, it produces boozy, vinegary or medicinal lots that no score can rescue.
