A new, advanced formulation of Go-Ferm

Go-Ferm Protect is a natural yeast nutrient that is added to the yeast hydration water before adding your selected yeast strain. Its complex formula provides your yeast with the proper sterols, unsaturated fatty acids and micronutrients needed to begin fermentation in optimal shape. The great thing about Go-Ferm Protect is that the proper nutrients and vitamins are introduced BEFORE the yeast is added to the must. This way 100% of the nutrients are available to your selected yeast strain and won't be stolen away by any indigenous yeast or bacteria that may be present in the must before your yeast can become established.

Go-Ferm Protect was created as a result of a multi-year study of problem fermentations by Lallemand and the National Agricultural Research Institute (INRA) in France. During this period, they looked at the adverse effects on the yeast from overripe fruit (>28 Brix), low nutrient levels, overclarification of the juice and poor fruit quality (Botrytis, rot, high bacteria count, insecticide and fungicide residue). Their research showed that musts deficient in sterols and unsaturated fatty acids made yeast more susceptible to ethanol toxicity (high alcohol), osmotic shock (high sugar), temperature and others stress factors. In response to this data they created the NATSTEP (NATural STErol Protection) process that incorporated sterols, unsaturated fatty acids, as well as vitamins and minerals into an advance yeast hydration nutrient: Go-Ferm Protect.

Go-Ferm Protect provides a combination of protective and nutritional benefits that ensure your yeast begins your fermentation in peak form! The best part is that if your fruit is in great shape then Go-Ferm Protect will simply help your yeast out that much more!

Go-Ferm Protect does not contain any DAP, as DAP is harmful to the yeast during the rehydration process. GO-Ferm is usually used in conjunction with our Fermaid K yeast nutrient; where Go-Ferm Protect is used at yeast hydration then Fermaid K is added at the first signs of fermentation and again after 1/3 sugar depletion.

Use at a rate of 1.25 g Go-Ferm Protect per 1 g of yeast.

A rough approximate of weight is 1 tsp = 3.2 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

DAP versus Go_Ferm?
Arnie Wetzstein on Sep 8, 2020
BEST ANSWER: DAP is a yeast nutrient, Go ferm is a yeast energizer.
Is this the same at Protect Evolution?
JOSHUA TAYLOR on Apr 6, 2020
BEST ANSWER: Go-Ferm Protect Evolution was previously known as Go-Ferm Protect, Fortiferm or Enoferm Protect. ... Go-Ferm Protect incorporates sterols and polyunsaturated fatty acids (for cell protection) together with vitamins and minerals to help ensure yeast survival and to help maintain fermentation activity to completion.

Updated my yeast nutrition regime.
Well packaged and fast shipping. I am about to use this product as part of my updated yeast starter and nutrition regime. I have no doubt this product will be as successful as all the other products I've purchased in the past.

Seems like this stuff works well.
Bought 2 yeasts that it was suggested nutrient additions be used. Used this mostly according to directions. Ferment proceeded with both yeasts beautifully. No stalling no off flavors. Time will tell about the quality of the wine but the yeasts fermented all the sugar really well so I am optimistic.

Love this stuff
Use all the time when hydrating yeast. I buy 5he 100 gram package and measure out into 10 grams to save. I have used this product for years, makes my yeast work well converting the sugars.

This stuff is awesome! It really kickstarts a yeast starter and cuts lag time down to next to nothing. Even since I started using this I have a very healthy, active fermentation going in about 12 hours or less.
