Good cheese
Works a charm alone, smells like powdered cheese

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.

Worked a treat for a stuck ferment.
I had a stuck ferment that was most likely due to a lack of nutrients. I thought I'd try and rescue it using this. It worked, and within a few hours of adding a couple of spoons to my ferment, it was bubbling away quite happily again. It continued to do so for the next week and fermented my elderflower champagne down to 0.990! Perhaps that's not how it should have been used but it worked so full marks from me!

Good to help fermentation
This is a good Guilty product that's easy to use in home brewing. Including this in a brew helps start a speedy fermentation. Overall great value for money ive used it all my brews since I discovered it.

Gives an extra boost to wines
I make wine using natural method. I have found some benefit with a little extra help and this product does just that. It stores well .

It's organic yeast nutrient.
Does what it should, helps with faster, cleaner home brews in wine, mead and ales )don't do larger) expensive here compared to the USA. Only criticism is the resealable opening the tear line is very close the the seal making it difficult to open and after a while difficult to close as it attracts moisture and clumps.

Cider yeast.nutrient
Probably a good product but you need to be a trained chemist to understand the instructions. Didn't use it in the end but couldn't send it back

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 Iโve 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

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!
