Description
The all-purpose brewpub strain of the 1990s and 2000s, clean enough for hoppy beer and full enough for stouts. It builds mouthfeel and pushes malt and caramel depth without leaving sweetness, and its low flocculation means slight haze unless you fine or cold-condition. It can start slowly on first generation, so give it extra oxygen.
