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

Works great!
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.

Seems to work
I made my first little bottle of mead using this as one of the ingredients. I didn't die. I have enough to last a long time. I'll have to make more.

Mead loves this
Makes for a happy yeast. This paired with a mead thats using goferm to rehydrate is the way to go, when making mead. Fermentation will be done in under 4 days, so you'd stage nutrient additions every 6 hours instead of 24 hours it just means it is healthy, so long as there's no off smells.

Moonshiner must have ^_^
This stuff was perfect, found a video on YouTube for making 40% ABV alcohol from sugar this was the key ingredient and it worked just like the video showed. And I’ve still got tons of it left, when I run out I will definitely be ordering more, have plans to try making wine or other alcohols from other recipes, never knew I could make powerful alcohol in the comfort of my own home rather than in the middle of a swamp

Great for balanced fermentation.
Bought so I could move away from DAP during normal fermentation overall. The powder is quite fine, and those with a sensitive nose should watch out as it has quite a strong smell. Being fine it can sometimes "burp" when releasing the package. Price wise it is obviously more expensive here than in the USA due to import.

Good Value Nutrient
I love using a yeast nutrient for my fermentations, keeps everything healthy and I find much more robust! Fermaid-O is a classic and often recommended option, I have made 3 brews with this material and have no complaints!
