Wild Yeast Hunting

with Wolter Jonkman and Ad van Nuenen

24 nov 2019

One of the most important tastemakers in your beer happens to be a living organism: yeast. Most beer brewers buy their yeast from expensive suppliers, but what to do if you want to work with your own? In this workshop, you will learn how to catch wild yeast from nature, how to manage a pure yeast culture and how to grow your favourite yeast strain.

De meeste bierbrouwers kopen hun gist van dure leveranciers, maar wat te doen als u met uw eigen wilt werken? In deze workshop leer je hoe je wilde gist uit de natuur kunt vangen, hoe je een pure gistcultuur kunt beheren en hoe je je favoriete giststam kunt kweken.

Wolter Jonkman

For Wolter Jonkman, yeast has always been more than just the thing you use to transform wort into beer. As soon as Wolter started brewing, the living organism caught his special interest. Wolter is a board member and the co-founder of the Bierkaai, an Amsterdam-based brewing association. He also co-organised the Amsterdam BeerFair, and writes a blog about brewing on

Ad van Nuenen

Next to his laboratory work at the Amsterdam medical center, Ad van Nuenen has been a passionate craft beer hobbyist. Together with Wolter, Ad co-founded de Bierkaai, for which he is an active board member.
