The EC-1118 strain is recommended for all types of wines, including sparkling, and late harvest wines and cider. It may also be used to restart stuck fermentations. This is the most popular and universal strain.
The RC 212 is recommended for red varieties where full extraction is desired. Lighter red varieties also benefit from the improved extraction while color stability is maintained throughout fermentation and aging. Aromas of ripe berry and fruit are emphasized while respecting pepper and spicy notes.
The D47 is recommended for making wines from white varieties such as Chardonnay and rosé wines. An excellent choice for producing mead, however be sure to supplement with yeast nutrients, especially usable nitrogen.
The K1V-1116 strain is a rapid starter with a constant and complete fermentation between 10° and 35°C (50° and 95°F), capable of surviving a number of difficult conditions, such as low nutrient musts and high levels of sulphur dioxide (SO2) or sugar. Wines fermented with the K1V-1116 have very low volatile acidity, hydrogen sulphide (H2S) and foam production.
The K1V-1116 strain tends to express the freshness of white grape varieties such as Sauvignon Blanc, Chenin Blanc and Seyval. The natural fresh fruit aromas are retained longer than with other standard yeast strains. Fruit wines and wines made from concentrates poor in nutrient balance benefit from the capacity of K1V-1116 to adapt to difficult fermentation conditions. Restarts stuck fermentations. Highly recommended for dry whites, aged reds, and late harvest wines.
