43 RESTART is the result of an innovative pre-acclimation process developed by Lallemand and approved by the Inter-Rhone Laboratory using Uvaferm 43. 43 RESTART’s resistance to the stressful conditions of stuck fermentations has been naturally increased. This process includes the addition of micronutrients, sterols andpolyunsaturated fatty acids to strengthen the yeast cell membranes. The yeast cells are more robust, acclimate more quickly and have a lower mortality rate after inoculation. 43 RESTART is sensory neutral and has been known to ferment up to 18% (v/v). It is a low SO2 and H2S producer with relatively low nitrogen demand. 43 RESTART is malolactic bacteria compatible. For best results use the 43 RESTART protocol including Reskue and Fermaid O. Restarts can be done in a few efficient steps.
