Description
Hosam Elhalis, writing alone, argues that a neglected yeast genus could improve coffee in a 2026 review. Coffee fermentation shapes bean quality and flavor. Most starter cultures rely on one standard yeast. Wild yeasts beyond it offer richer chemistry and genetic range. Species of Pichia, a yeast genus proven in wine and beer, are barely tried in coffee.
The review collects what is known about Pichia species and their traits. Several species ferment strongly even under flooded, washed-coffee conditions. Distinct members bring gifts: heavy ester output for aroma, enzymes that break down pectin, and tolerance of harsh conditions. Together they can steady the microbial mix and deepen flavor. The author calls Pichia an underexploited resource for washed coffee. Knowledge from wine and beer, he argues, can be transferred to guide coffee trials.
