Description

If you’re rehydrating beer yeast, it’s quick and easy to ensure a perfect ferment by adding FermStart by CellarScience.  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 flavor 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 flavors and fermentation behavior 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.

Firm Start
I have used this in the past and with the proper amount of potassium metabisulfite and firm aid additions the fermentation will go to dry. This year I picked 367 lbs. of cab and zin from my vines and tomorrow I will crush and destem. I will adjust ph and acid as needed and do a cold soak for 4 days with warming and yeast addition to start fermentation.

FermStart yeast nutriaent
We were extremely pleased. Fermentation was working within 12 hours.We plan on using the nutrient with all of our future rehydrations.
