The dynamic synergy of Lalvin BM 4x4 has been considered to transmit all the advantages of BM45. The BM 45 was isolated as part of a research program in Montalcino, in the heart of the Tuscany region (Italy), and selected in collaboration with the consortium of Brunello di Montalcino wines and the Universita Degli Studi di Siena.

Lalvin BM4x4 is a blend of Lalvin yeasts that will bring out the best in both red and white wines. Unique to BM4x4, during the growth phase, this yeast blend has the capacity of releasing a significant quantity of polyphenol-reactive polysaccharides into the fermenting must. The quantity and the quality of the polysaccharides released during fermentation facilitate the production of red wines with great mouthfeel and improved color stability, with dependable fermentation kinetics under difficult fermentation conditions. In whites, BM 4x4 releases a high level of esters responsible for fruit aromas. It also brings roundness to the mouthfeel and facilitates malolactic fermentation. Temperature range of fermentation: 16-28C Moderate fermentation speed Alcohol tolerance: 16% High nutritional requirements.
