White Wine
For flavour-rich, cool climate Riesling and aromatic whites.
R-HST was selected for its exceptional oenological properties in Riesling from trials conducted from 1991 to 1996 in the Heiligenstein region of Austria. With appropriate nutrition R-HST, enhances fresh varietal character producing crisp, citrus, lime, fl oral (rose) and mineral notes, and contributes body and mouthfeel for an overall complexity and elegance. R-HST improves the fruity varietal characters of Riesling. Experience under Australian conditions suggest that best results are obtained with this yeast when the fruit is harvested below 12° baumè.Fermentation Speed
