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 quanitity 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: 60° to 82° F. Moderate fermentation speed. Alcohol tolerance: 16%

BM 4X4..How as stated in the Description? It brings roundness to the mouthfeel and facilitates malolactic fermentation. Particularly the malolactic fermentation. I was thinking of using 71-B to reduce Malic Acid but pitched BM 4X4 in 6-gal Cabernet
BM 4X4 is an aggressive fermenting yeast, and will give a drier profile to your Cabernet than 71-B.
