White Labs · Super High Gravity Ale WLP099
- 18.0 – 21.0°C
Super High Gravity Ale (WLP099) from White Labs is a distinctive ale yeast designed to effectively ferment in environments with high sugar concentration. It comes in a liquid form, enabling easier measurement and pitching into the brew. The yeast is characterized by an impressive attenuation of 85.0%, which refers to the percentage of sugar that the yeast will ferment out. The yeast also has a medium flocculation rate, meaning it forms moderate clumps and sediments after fermentation.
Its high alcohol tolerance makes it perfect for brewing strong ales, barley wines, and other high gravity beers. It operates ideally at fermentation temperatures of 64.4-69.8 °F (18.0-21.0 °C), ensuring an efficient fermentation process and production of desirable flavors. When used in brewing, WLP099 yields beer styles such as English Barleywine, Russian Imperial Stout, and Old Ale, with a flavor profile that supports rich, robust, and complex beers. It's the go-to yeast for those seeking to produce bold beers with high alcohol content and a complexity of flavors.
