Selected from Riesling trials conducted from 1991 to 1996 in the Heiligenstein region of Austria.
Tolerates fermentation temperatures as low as 10°C(50°F) and alcohol levels up to 15% (v/v). In very cold fermentations, allow the temperature to increase toward the end for a clean finish.
Lalvin R-HST® has a short lag phase and generation time, even at cold temperatures. This allows it to dominate and persist over spoilage yeast such as Kloeckera apiculata, where other S. cerevisiae might have difficulty.
Retains fresh varietal character while contributing structure and mouthfeel. It can produce crisp, premium white wines suitable for aging.
