Description

Fermaid O is a newer formulation of the same Fermaid K that winemakers everywhere have learned to trust their ferments to. The main difference in composition between the two, is that the Fermaid O has replaced the inorganic DAP with an organic source. In terms of how this benefits the winemaker, there are several points!

Features:

  • Organic Nitrogen is easier for your yeast to digest, resulting in a smoother, more consistent fermentation.
  • Fewer fermentation spikes means better yeast health, and the ability to ferment to its full capacity.
  • Compared to DAP, Fermaid O will result in lower heat output from the yeast, and lower levels of negative sulfur compounds.


This is a nutrient which will boost the quality of wine, regardless of process. Lower heat production, less negative flavor compounds, better overall fermentation kinetics and flavors!

To Use:
Use at a rate of 1.5g / gal of must/juice.

some ofmy bold reds in foothills of El Dorado county are nitrogen starved 1/2 way through primary fermintaion. These helps those lacking red bold wines to complete dryness

I’m using Formaid O to insure a complete fermentation of sugar. It seems to be making a difference.

First time experience
I just used Fermaid O in a batch of Black Raspberry (which I grow) wine. I had a good but not foamy fermentation. Fermented down to SG 0.992. So, based on this one experience, I can recommend it, as it does it's job. Bigger tests for it as the harvest season approaches... Cheers!

Working as expected so far
I'm using the Fermaid O as my sole nutrient in the mead. Way to early to judge how it will come out, but it seems to be fermenting as expected.

Major Improved Mead Fermentation
This product has been the biggest improvement in my mead fermentations so far. I first used this with DAP but have recently moved to an all Fermaid O fermentation and my meads have never been this clean tasting so early. I cannot recommend this product enough.
