Product details

Lalvin R2™ was isolated in the Sauternes region of Bordeaux by Brian Croser of South Australia. It has excellent cold temperature properties and will ferment as low as 5°C. Without good nutrition and protection against osmotic shock, it can tend to produce VA. For this reason, proper nutrition and protection during rehydration and during fermentation is recommended. R2™ helps produce intense, direct fruit-style whites by liberating fruit and floral aroma precursors. It is recommended for aromatic white varieties, such as Sauvignon blanc, Riesling and Gewürztraminer. It is classified as a Saccharomyces cerevisiae bayanus.
