## Description

North Mountain Supply Fermaid O - 8 oz Plastic Jar. This is an organic nitrogen source that helps to nourish yeast, improve aromas, and allows for good control over fermentation. Reliably lowers peak fermentation temperatures and improves fermentation kinetics (especially at the end of fermentation), resulting in fewer sulfur off odors like H2S.

Review: Works as should and fresh - Great stuff and great container
Review: Works great. - Works great. Forgot to get more nutrient before starting another batch and got this expedited. Bubbles slowed way down and I was darn near a stall. Then the package arrived, I dosed and those yeast are going crazy now, but with no cap because I put bentonite in up front. Looks like I have a good one going.

### ⭐ Is this a joke???
*by A***R on June 18, 2025*

Idk how to feel honestly. Hopefully it’s still good product. It looks like it’s been opened and used before according to everything I’ve seen…. Honestly not a fan about that. Edit* Will be adding photos every time I receive a damaged product.
