Works for Mead
Works well for brewing. I only make mead and it works well step feeding with this. Does not produce off flavors like UREA does. It does have a terrible smell to it but again, it does the job

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

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.

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!

Worked perfectly to give your homebrew some help during fermentation.
