Jasper Yeast

Jasper Yeast jasperyeast LLC is a small independent producer of local, tried-and-true and hard to find yeast strains for breweries of all sizes.

We have never increased our prices, and are the most affordable liquid lab around. jasperyeast LLC was started by Jasper Akerboom in June 2014. Jasper Akerboom received MS in molecular sciences and PhD in microbiology at Wageningen University, the Netherlands. After isolating numerous strains from localities all over the USA, as well as from old barrels and century old wine, he decided to share th

ose strains with the local craftbrewing and homebrewing community. We currently are growing small batches of several strains, and offer consulting services to craftbreweries on QA/QC and cellaring.

Very excited to see what Maciej has to share, I have not seen the data yet.

🚀 Exciting week ahead! Next weekend I’ll be at the MBAA meeting at the Molson Coors site in Elkton 🍻, where I’ll be presenting our recent work together with Jasper Yeast (Jasper Akerboom Jasper Yeast) and Kaapse Brouwers (Etienne Vermaulen) Kaapse Kaap

Our focus: sugar management and how an innovative approach can give brewers more actionable insights and a deeper understanding of yeast behavior in their brews. As always, all to help create more flavorful beer 🍺✨.

I’m really looking forward to this opportunity to connect with the brewing community on the other side of the Atlantic 🌍🤝. It’s always inspiring to exchange knowledge and ideas that push our craft forward.
