Contains various isolates from lambic-producers, B. bruxellensis, B. anomala, B. lambicus, and B. naardenensis. For those who want the most from Brett yeast, whether a 100% Brett fermentation is desired or adding to secondary aging projects.
RC 212 Lalvin Bourgovin 68-86   Low The RC 212 is a low-foaming moderate-speed fermenter with an optimum fermentation temperature ranging from 20° to 30°C (68° to 86°F). A very low producer of hydrogen sulfide (H2S) and sulfur dioxide (SO2), the RC 212 shows good alcohol tolerance to 16%. 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.
ICV D-47 Lalvin ICV D-47 59-68   Medium The ICV D-47 is a low-foaming quick fermenter that settles well, forming a compact lees at the end of fermentation. This strain tolerates fermentation temperatures ranging from 15° to 20°C (59° to 68°F) and enhances mouthfeel due to complex carbohydrates. Malolactic fermentation proceeds well in wine made with ICV D-47. 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.
71B-1122 Lalvin 71B-1122 (Narbonne) 59-86   Medium Has the ability to metabolize high amounts (20% to 40%) of malic acid. In addition to producing rounder, smoother, more aromatic wines that tend to mature quickly, it does not extract a great deal of phenols from the must so the maturation time is further decreased. The 71B is used primarily by professional winemakers for young wines such as vin nouveau and has been found to be very suitable for blush and residual sugar whites. For grapes in regions naturally high in acid, the partial metabolism of malic acid helps soften the wine. The 71B also has the ability to produce significant esters and higher alcohols, making it an excellent choice for fermenting concentrates.
K1V-1116 Lalvin ICV K1V-1116 (Montpellier) 50-95   Low 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 sulfur dioxide (SO2) or sugar. Wines fermented with the K1V-1116 have very low volatile acidity, hydrogen sulfide (H2S) and foam production. 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 sulfur dioxide (SO2) or sugar. Wines fermented with the K1V-1116 have very low volatile acidity, hydrogen sulfide (H2S) and foam production.
EC-1118 Lalvin EC-1118 (Champagne) 50-86   Low The fermentation characteristics of the EC-1118 — extremely low production of foam, volatile acid and hydrogen sulfide (H2S) — make this strain an excellent choice. This strain ferments well over a very wide temperature range, from 10° to 30°C (50° to 86°F) and demonstrates high osmotic and alcohol tolerance. Good flocculation with compact lees and a relatively neutral flavor and aroma contribution are also properties of the EC-1118. 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.
