WHC Labs High Voltage (Lutra) Dry Brewing Yeast 500G

WHC Labs High Voltage is a clean, heat tolerant dry brewing yeast for brewers who want malt and hops to lead the flavor. It produces relatively few fruity esters even at warmer fermentation temperatures. WHC Lab recommends the cooler end of its range for lager style beers and warmer temperatures for ales. That makes it useful for pseudo-lagers, Kölsch beers, pale ales, IPAs, brown ales, and stouts. High Voltage is an ale yeast (Saccharomyces cerevisiae), so a lager style beer made with it is not fermented with traditional lager yeast.

Warm fermentation can shorten tank time and reduce cooling needs, while High Voltage’s high flocculation helps the beer clear after fermentation. Its very high nitrogen demand makes adequate wort nutrition especially important, particularly for high gravity batches. WHC Lab says rehydration and wort oxygenation are generally unnecessary unless brewing a very high gravity beer.
