Lalvin BM4X4 (1 package 5g BM 4x4) Dried Wine Yeast
Included is 5 grams of BM4X4 yeast in a vacuum package for 5 to 6 gallons of wine.  Lalvin brand BM4X4 is known for its dynamic synergy of BM45 (enhanced mouth feel, complexity, and color stability in premium red wines) with a faster (around 10 days instead of 20 days in the lab) and more secure ferment for both red and white wines.  When brewed correctly, a tasting panel preferred BM4X4 4 to 1 over a control yeast.  Not good for restarting stuck wines. When it arrives, the yeast may be stored at 40F up to one year to keep the yeast activity at 95% or above, but it is always best to use as soon as possible.  This 5g of yeast is enough to make a 5+ gallon batch of wine with a 15% alcohol tolerance.  For best results, dissolve 5g yeast in  cup 95F - 104F water for 20 minutes before adding to grape concentrate within 20 F temperature of the hydrated yeast.  People 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. It also brings roundness to the mouthfeel and facilitates malolactic fermentation.
