FermStart is a concentrated micronutrient blend that helps yeast during the critical phase in which they transition from dried and dormant back into healthy and active.
FermStart is added to your rehydration water so that your yeast absorbs the nutrients as they absorb the water. When the Brix level is above 14 in must, or the gravities exceed 15° Plato or 1.060 starting gravity in wort, it is recommended to rehydrate your yeast. To ensure a perfect ferment that reaches its full flavor potential, rehydrate your yeast with FermStart from CellarScience™.
FermStart is a super concentrated formula, which is very convenient when you are rehydrating large amounts of yeast.
Beer Yeast Examples:
12g yeast - Add 2g FermStart to roughly 50ml of water
The Science of How it Works
FermStart is rich in readily assimilable amino acids, sterols, vitamins, and natural glutathione. Readily assimilable means that the size of the molecules present in FermStart are extremely small and easily absorbed by the yeast cell. The availability of readily assimilable amino acids allows the yeast cell to skip the step in which amino acids would be synthesized within the cell. This saved energy is instead directed into multiplication, which leads to faster fermentation starts and allows the selected yeast to out-compete wild yeast that may impart off-flavors. Sterols help the cell membrane regain and maintain elasticity helping to ensure a perfect start and continued performance throughout the fermentation. Glutathione is extremely important for maintaining intracellular health by preventing damage to cellular components during the very oxidative process of rehydration.
For a full yeast nutritional plan, use FermStart when rehydrating yeast, FermFed at the onset of fermentation, and near the end of fermentation.
