Species: Saccharomyces cerevisiae var. diastaticus
STA1 gene: Yes
From England, this yeast can ferment up to 25% alcohol. Produces dry beer. Ideal for beers aging forextended periods of time. Produces more esters with increasing gravity. Malt dominates at lower gravities.
Brewing Properties of Super High Gravity Ale Yeast
The functional properties of brewing yeasts have a direct impact on the performance, quality and economics of the resulting beer.
The alcohol tolerance determines the ABV at which yeast cells go dormant and stop fermenting.
Attenuation refers to the percentage of sugars converted to alcohol and carbon dioxide, as measured by specific gravity.
Flocculation refers to the tendency of yeast to form clumps called "flocs" that drop in order to make the beer clear.
The optimal temperature is the range in which the yeast performs best without putting off any off-flavors. Pitching the yeast into wort usually happens at the low end of the temperature range.
