Fermaid O

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.

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!

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.

I recently tried Youngs Yeast Nutrient and was sorely disappointed, and thought it ruined the quality of my batch. THIS nutrient SAVED it, it’s so effective at activating and assisting yeast without compromising flavour! Very easy to use but be cautious at how much you use as it’s easy to cause an accidental spillage. Worth every penny.

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 .

Very fine yeast

Great service

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

This is a great product.

Good product. Just wish it came in a larger more economical size

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!

the yeast love it! however make sure you seal it well and use it fast, it will get clumpy and sticky if moisture gets to it.

I am a novice mead maker. I have been using this product to help the yeast in my meads. As far as I can tell, it has not left any off flavors or odors. I just taste the fermented honey. So far, it is the only yeast nutrient I use. It seems to keep the yeast going for quite a while, as I have had all of my batches fermenting for extended periods with this product.
