Lalvin BM 4x4 is a new yeast blend developed by Lallemand which combines the incredible benefits and flavors of the BM 45 strain, with additional strains for improved reliability and consistent fermentation in potentially difficult environments.
The BM 4x4 yeast blend creates an improved mouthfeel and color stability. In white wines, BM 4x4 releases a high level of esters which helps promote fruit aromas.
BM 4x4 has high nutritional requirements. Consider using Fermaid K or other yeast nutrients depending on what your recipe requires.
Ideal fermentation temperatures for Lalvin BM 4x4 is between 60.8 and 82.4 degrees Fahrenheit.
Lalvin BM 4x4 should be stored dry between 39 and 53 degrees Fahrenheit when not in use.
Sold per each. 5 gram pack sufficient for 5 gallons of must.
BM 4X4® is a blend of BM45™ and another yeast known for its fermentation reliability. BM45™ is known and appreciated around the world for its round mouthfeel and stable color (see above description for BM45). However, BM45™ is a slow fermenter and can require substantial nutrients to complete fermentation successfully and without the production of sulfides. While BM45™ has a very strong following among winemakers who enjoy its slow fermentation and its suitability for long maceration programs, there are others who desire the attributes of BM45™ but with a more timely and secure fermentation. BM 4X4® achieves this goal. During the yeast growth phase, BM 4X4® 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 color stability, with dependable fermentation kinetics under difficult fermentation conditions. In whites, BM 4X4® releases a high level of esters responsible for fruit aromas and also brings roundness to the mouthfeel.
