Description

The Fermaid line of products are a range of nutrients that have been adopted from winemaking and put to use supporting beer fermentations as well.
   
Fermaid O is a newer formulation of the long trusted Fermaid K nutrient which replaces the inorganic DAP in Fermaid K with an organic source of nitrogen instead. The organic nitrogen in Fermaid O is better for your yeast, and that results in better beer!
 
Organic Nitrogen is easier for your yeast to digest, resulting in a smoother, more consistent fermentation. Fermaid O fermentations show fewer temperature spikes, which minimizes negative effects that can be caused by heat. Compared to DAP, Fermaid O results in more consistent and complete fermentation, and lower levels of negative sulfur compounds and other off-flavors.
 
Use at a rate of 1.5g / gal of wort. Dissolve in a small amount of wort or water and add to your fermenter at pitching.

To make fast, clean mead

I read that yeast handle this better than the inorganic sources of nitrogen.

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.

Just what the doc ordered
This product does very thing it says it does. I would risk fermenting without it!

great product but beware...
Great product but keep it away from your cats! Two years in a row our cats have pulled this out of a box and gone nuts with it ripping the bag open and spreading it all over the place. It seems to have a more powerful draw than catnip.
