LALVIN BM45™

(Saccharomyces cerevisiae cerevisiae)

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, complementing wines with great mouthfeel and improved color stability. BM45™ is used on red varieties to complement jam, spice and earthy wine styles. It is also used to minimize vegetal characteristics. Some winemakers use BM45™ on Chardonnay as a blending component to increase mouthfeel. Not malolactic bacteria compatible.
