When its time to brew some malt forward beers, Sovereign is ready. This is a very traditional, non-flocculent English ale strain that makes a great choice for your barley wines, ESBs and pales. Sovereign stays in suspension and dries out higher gravity brews quickly. White Labs Equivalent: WLP013 Wyeast Equivalent: WY1028 Flocculation: Medium-Low Optimum Fermentation Temp: 60-70 F For best results we always recommend ordering an ice pack with your liquid yeast.
