RHST Dry Wine Yeast
Please select from the following option(s) to see pricing and availability.

R-HST was selected for its exceptional oenological properties in Riesling from trials conducted 1991 to 1996 in the Heiligenstein region of Austria. R-HST has a short lag phase and generation time, even at cold temperatures. These features allow it to dominate and persist over spoilage yeast such as Kloeckera apiculata, where other Saccharomyces cerevisiae might have difficulty. A relatively neutral strain, R-HST retains fresh varietal character while contributing body and mouthfeel. R-HST produces crisp, premium white wines intended for aging. R-HST is best used when the most transparency between a fruit and a finished wine is sought. This can be useful for showcasing quality fruit and terroir differences, as well making sure original fruit characters are retained in a final blend. Best results from 50 to 86 degrees F, with an alcohol tolerance to 15%.

Great for Riesling!
I decided to go for this yeast for my Riesling/Traminer blend, and must say it adds great flavor and structure to the wine!

That being said, though the ideal temperature is listed between 50 and 86 degrees, once the must gets over 70, it will start fermenting like crazy. I ended up putting my fermenter in a swamp cooler just to make sure it didn't over-ferment.
