Our selected wine yeasts

Wine yeasts, mastered from nature to bottle

Without yeast, there is no wine. But with the right yeast – and the right partner – there is a clearer path to quality, consistency, and site expression. We select Saccharomyces and non‑Saccharomyces wine yeast strains from nature, translating biodiversity into reliable, high‑value solutions for modern winemaking.

Why Lallemand wine yeasts?

End-to-end mastery you can trust

From selection to production, we control the critical steps that make performance consistent and quality reliable, so you can focus on wine, not uncertainty.

Since the early 1970s, Lallemand Oenology has been a pioneer and a global leader in selecting and producing natural wine yeasts, building deep expertise, collaborations and know‑how alongside winemakers worldwide.

Innovations that serves the cellar

Our approach combines nature‑inspired selection with leading‑edge science, advanced techniques, and innovative production processes—turning research into practical solutions you can use in the winery.

Close to winemakers, close to real challenges

We work side‑by‑side with winemakers around the world to anticipate and address today’s challenges: evolving grape composition, tighter margins, sustainability constraints, fast‑changing consumer preferences, respecting site expression and rising expectations for sensory precision.
