Review by Thomas Williams on 10/20/2020

I’m hooked on this yeast. I tried this yeast amount others that I ordered and quickly ordered more even though I still have many other unused yeast types. My goal was very high attenuation with very limited residual sugar in a high gravity ale. My high temperature brewing environment produced batches fermented down to dry wine levels but the esters of banana and fruit gave it a sweet impression without residual sugar and no dry taste or body.

According to reports, this is the same yeast formerly sold as M27. It is actually a Saison yeast, not what most brewers expect as a "Belgian Ale" yeast. M27 is (was) notorious for extreme attenuation, typically getting down below 1.010 even in high-gravity beers and sometimes going all the way to 1.000. Definitely peppery and spicy flavor profile - not fruity. Makes a decent Leffe clone if you mash high (158F). If you mash at 154 or lower, and don't have much crystal malt in the bill, this yeast will give you a very dry beer with lots of yeast character and a hot alcohol component - plan to age it for a while before drinking.
