a must have for mead! keeps the yeast beasties happy for the long run! doesn't add any noticeable flavor.

### ⭐⭐⭐⭐⭐ Works great!
*by J***. on July 5, 2026*

Works perfectly! The only downside is the container it comes in. I understand this keeps the cost down potentially but having it in a jar would make managing the container/Ingredients while making your batch as well as storage would be so much easier.
