The Lalvin RC 212 Dried Active Yeast is an exceptional yeast strain, specifically formulated to enhance the characteristics of both young and aged red wines. This product comes in a convenient packaging of five 5g sachets, designed for ease of use and optimal performance. Each sachet has the capability to treat between 4.5L and 23L of must, making it suitable for both small batches and larger wine production activities. With a total weight of 30 grams, this product provides a well-rounded solution for winemakers seeking to elevate the quality and flavor profile of their red wine creations.
One of the standout features of the Lalvin RC 212 is its high alcohol tolerance, capable of withstanding alcohol levels up to 16% ABV. This attribute is particularly beneficial for crafting bold, robust red wines that are characteristic of the Burgundy region. The yeast operates effectively within a fermentation temperature range of 20°C to 30°C, allowing for flexibility in various winemaking environments. The strain is derived from a traditional heavier-style Burgundian Pinot Noir, signifying its reliability and robustness in producing wines that exhibit rich color and structure.
The Lalvin RC 212 yeast functions with a moderate fermentation rate, initiating vigorous activity within a relatively short lag phase. Users may observe rapid fermentation, typically within one day, with active bubbling—an indication of healthy yeast activity. The low production of volatile acidity and sulfur dioxide ensures that the wine maintains its intended flavors without undesirable off-notes. Furthermore, the yeast exhibits a low cell wall absorption of polyphenols, allowing for the expression of the fruit's natural character without excessive pressure from the yeast.
Designed for the modern winemaker, Lalvin's yeast sachets are straightforward to integrate into the winemaking process. The packaging not only preserves the yeast effectively but also simplifies the measurement and addition to the must. With the requirement for high levels of assimilable nitrogen, users can enhance fermentation outcomes by pairing this yeast with appropriate nutrient additions, ensuring that the yeast thrives throughout fermentation and leads to the desired flavor complexity.
