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, 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.
