Valued by winemakers seeking mid palate structure while at the same time respecting varietal expression. "Dynamic synergy" - the sensory attributes of BM45 with greater fermentation reliability in difficult conditions.

BM4X4 is a blend of two yeast strains: BM45 plus a complementary yeast known for its fermentation reliability. BM45 is known and appreciated around the world for its round mouthfeel and stable colour (see description for BM45). While BM45 has a very strong following among winemakers who appreciate its suitability for long maceration programs, there are others who desire the attributes of BM45 but with a more timely and secure fermentation. BM4X4 achieves this goal. During the yeast growth phase, BM4X4 has the unusual 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 colour stability with dependable fermentation kinetics under difficult fermentation conditions. BM4X4 is also well suited for full bodied white wines, bringing roundness to the mouthfeel and enhancing aroma.
