I had a strange epiphany after using this yeast strain for the first time; I love horses or sweaty blankets, or some combonation of the two.  How and why has my life not lead me to a stable, I ask myself.  All of those times, as a child, I thought the "horse girl(or guy)" at school was odd, and now I found myself to be the "horse blanket" guy.  Is this a mid-life crisis or a simple yeast strain fling.  Is this like that summer I couldn't stop fermenting the French Saison strain in the back of the shop? No. This is more than that. I was so infatuated I found myself running up to strangers exclaiming, "You'll love it, it's just like horse sweat!" or regularly explaining on dates "I ordered us a beer that tastes like they wrung out a jockey's crotch garment after a horse race!". Next thing I knew, I was in the Flanders region of Belgium, swooning the local milk maidens and charming the drinking authorities into letting me behind the scenes. Sorry, I got lost there, but long story short is: brew a batch of some barnyardy George Orwell stuff and get on the horn with a marriage proposal to that "horse girl (or guy)" you may have been less than kind to in the past, because your life is about to get real FUNKY!!! 

This strain of wild yeast was isolated from brewery cultures in the Brussels region of Belgium. It produces the classic “sweaty horse blanket” character of indigenous beers such as gueuze, lambics and sour browns and may form a pellicle in bottles or casks. The strain is generally used in conjunction with S. cerevisiae, as well as other wild yeast and lactic bacteria. At least 3-6 months aging is generally required for flavor to fully develop.

For best results we always recommend ordering an ice pack with your liquid yeast.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.
