Description
A Czech microbrewery isolate for smooth, lightly malty pilsners that still let hop aroma through. It is slow to start but finishes reliably, so Jasper suggests pitching warm on the first generation and lagering at least three weeks. Drops a very dense cake, which matters if you plan to repitch.
