Description
A yeast-plus-enzyme blend for very high-gravity beers: barleywine, imperial stout and barrel-aged strong ales that a normal strain would quit on. The sheet quotes apparent attenuation past 100 percent because the enzymes keep feeding it dextrins; we cap the stored band at 100. Treat package stability as a real concern.
