Good Nutrient
I'm new to the homebrewing game, so purchasing this was the first time I ever used yeast nutrients and so far, it's worth the money. My yeast loves this stuff and when I step feed them, they instantly start getting active eating it up. Easy to use, just measure what you need and dump it in. As far as quality I am not too sure since this is my first and only brand trying nutrient, but the couple of brews that have finished never had any off smells or taste so I'm guessing quality is good. I will be trying other brands to see if I like any others but for right now, this what I will be recommending for beginners like me!!

Seems like a Good product to me
Some people are showing that their seals are broken. I have had no issues. As you can see the seal is vaccumed down.
