STA1 :


This specialty blend of Kveik yeast and Lactobacillus sp. has been designed to create a unique co-ferment of yeast and bacteria resulting in a mildly fruity and tart beer. Fermenting with both yeast and bacteria at the same time provides a faster and cleaner souring profile. This blend is ideal for beer styles like Berliner weisse, gose, or experimental beers.

Although this blend can be used at 80°F(27°C) or higher, if used between 90°-100°F (32°-38°C) fermentation can be completed within 72 hours.

It's recommended to keep wort hopping low and IBU's below 5-7 to ensure the bacteria is not inhibited.
