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.
