Works wonders

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.

Effective but expensive
Seems effective it’s just a very small quantity for the price.

Amazing!
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.

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.

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.

Pure natural
I only started using Fermaid O. Could not get over how well it works. My last batch fermented 3 days quicker the normal and the airlock was steady all the way through. I’ll be using it from now on. Don’t like chemicals so for me it a great asset to brewing !
