Saison lovers, have we got a saison yeast for you! Saisonstein's Monster is an original genetic hybrid of a French and a Belgian saison yeast, developed by and exclusive to Omega Yeast Labs! Versatile, aromatic and attenuative, it is an excellent choice for high gravity worts, fermenting more reliably and thoroughly than either the French or Belgian strains on their own! It produces beers with a silky mouthfeel that are spicy, complex, tart, dry and crisp. It has a bit of bubblegum character from its Belgian parentage, and tends to be more fruity with less phenolics that a typical French saison strain.

Omega Yeast Labs brings you fresh, healthy and unique yeast! Their yeast packs contain the optimal number of viable yeast cells to ferment 5 gallons of wort up to 1.060 O.G. With a collection of strains that include standard yeast, unique strains created in-house, and rare strains of yeast and bacteria, Omega Yeast Labs is a wonderful source for yeast for all your fermentation projects!


We include complimentary ice packs with ALL liquid yeast orders (if required), but cannot guarantee that the ice packs will stay cold during transit, and thus the yeast can potentially be exposed to hot temperatures. We highly recommend ordering dry yeast during the hot summer months or if you are ordering from a warmer climate. Many times during the winter an ice pack is not needed so we make the determination based on current temperatures and the destination!

It is a monster
This yeast ran through the Hi-Razz Saison like nothing. 1 week after pitching the yeast starter, it was done. Definitely buying it again.
