Fermstart Yeast Rehydration Nutrient by Cellar Science

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 gravities exceed 15° Plato or 1.060 starting gravity, it is recommended to rehydrate your yeast. To ensure a perfect ferment that reaches its full flavour potential, rehydrate your yeast with FermStart.

How Much?

FermStart is a super concentrated formula, which is very convenient when you are rehydrating large amounts of yeast. Use 1 gram of Fermstart for every 4 grams of yeast. We offer some suggested ranges for the amount of water to use below.

Examples:

12g yeast - Add 3g FermStart to roughly 50ml of water

500g yeast - Add 125g FermStart to roughly 1500 ml 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. This is obtained by centrifuge and allows FermStart to be extremely concentrated and not contain filler.

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. Faster yeast cell multiplication means a faster start allowing your yeast to out-compete wild yeast. Wild yeast have unknown flavours and fermentation behaviour so it is important to give the yeast you selected the best chance to dominate the fermentation.

Sterols help the cell membrane regain and maintain elasticity helping to ensure a perfect start and continued performance throughout the fermentation. The strong cell membrane helps ensure that the yeast can survive and complete alcoholic fermentation under tough conditions.

Glutathione is a very special natural antioxidant and detoxifier made up of three amino acids cysteine, glutamate, and glycine. It is extremely important for maintaining intracellular health by preventing damage to cellular components during the very oxidative process of rehydration.
