The Cantillon building is a collection of history, not only because of the Brussels Gueuze Museum housed inside, but also due to the amazing collection of apple orchard yeasts that have grown and developed it it’s walls for 100 years.  By combining these historical yeasts with the yeasts of Brussels, the terroir at Cantillon leads to one of the most unique, special combination of yeasts and bacteria found anywhere in the world for spontaneous fermentation.

SpontanAir has successfully harvested this special air bouquet and preserved it in it’s traditional form for your spontaneous fermentation projects.

Cantillon yeasts are some of the most sought after in the world as they are known to grow into whales. Don’t be surprised if their is a spider in your jar; that’s natural and helps preserve the air.
