Neutral character, with low fusel-alcohol production. Ferments dry.
**This strain has been genetically typed in our lab using polymerase chain reaction (PCR). Through this genetic testing, we have determined WLP740 Merlot Red Wine Yeast to contain the STA1 gene (glucoamylase), a potential indicator ofÂ Saccharomyces cerevisiae var. diastaticus. Brewers yeast are natural hybrids, which make it possible for certain strains to display elements of the STA1 gene. These strains have the ability to utilize some dextrins (unfermentable sugars), resulting in higher levels of attenuation than what is considered typical.
