Lalvin Yeast, BM45, 30g

Lalvin BM45 was isolated in the early 1990s in collaboration with the Consorzio del Vino Brunello de Montalcino and the University of Siena. BM45 is a relatively slow starter and is well suited for long maceration programs. It has high nitrogen requirements and can produce sulfides if nutrient starved. When used in whites, BM45 benefits greatly from rehydration with proper nutrition. During fermentation, BM45 produces high levels of polyphenol-reactive polysaccharides, resulting in wines with great mouthfeel and improved color stability. BM45 is used on red varieties to contribute jam, spice and earthy elements. It is also used to minimize vegetal characteristics. Some winemakers use BM45 on Chardonnay as a blending component to increase mouthfeel.
