works great
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.

Feeds the yeast with no off flavors.
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.

Bubbles
My yeast seems to like it. They haven't outright said it, but I assume through their bubbly attitude that is how they feel.

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!

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!

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.
