Yeast innoculation

Yeast innoculation

Yeast-inoculated green coffee beans are transforming fermentation, giving producers greater control over flavour development. By introducing specific yeast strains, they can shape acidity, enhance floral aromas, and bring out tropical fruit notes with precision. This controlled fermentation method ensures consistency while unlocking new and exciting taste profiles, making yeast-inoculated coffees some of the most distinctive on the market.

Your guide to Yeast innoculation

  • What is yeast inoculation in coffee?

    Yeast inoculation is a controlled fermentation process where specific yeast strains are introduced to influence flavour development. Unlike traditional methods that rely on naturally occurring microbes, this technique allows producers to fine-tune acidity, sweetness, and aroma. By selecting particular yeasts, they can create yeast-inoculated green coffee beans with more predictable and repeatable flavour outcomes.

  • What is the benefit of yeast inoculation?

    Yeast-inoculated coffee offers greater consistency and enhanced flavour complexity. Producers can steer the fermentation process to highlight specific characteristics, from vibrant fruit notes to delicate florals. This precision not only improves cup quality but also increases the coffee’s value, as buyers seek out unique and well-defined profiles.

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

    The impact on flavour depends on the yeast strain used, but common results include bright citric and malic acidity - bringing apple and citrus-like notes - along with intensified floral aromas and tropical fruit flavours. Yeast-inoculated green coffee stands out for its clarity, vibrancy, and structured complexity, offering roasters an exciting new dimension to explore.
