Your guide to Yeast innoculation

  • What is yeast inoculation in coffee?

    Yeast inoculation is a fermentation technique where producers introduce specific yeast strains to guide flavour development more precisely. Unlike traditional fermentation, which relies on naturally occurring yeasts and bacteria, this controlled approach allows producers to shape the coffee’s profile with greater accuracy. By selecting particular yeasts, they can influence the compounds formed during fermentation, resulting in more predictable and intentional flavour outcomes.

  • What is the benefit of yeast inoculation?

    This method allows producers to unlock flavour potential that elevates a coffee from ordinary to exceptional, increasing its value. It also improves consistency—because the fermentation process is controlled, producers can reliably achieve specific flavour profiles, reducing the unpredictability of naturally occurring microbes.

  • How does yeast inoculation change the flavour profile of coffee?

    Yeast-inoculated coffees often develop a bold and complex character, with enhanced acidity—typically bright citric and malic acidity, which brings apple-like notes. Depending on the yeast strain used, the process can also accentuate floral aromas and tropical fruit flavours, creating coffees with a distinctive and vibrant taste.
