Does anyone make their own yeast nutrient. BYO Magazine had a interesting article about the nutrients required and I was wondering if anyone already makes one?
An excellent source of yeast nutrient is ... yeast. Many LHBSs will give away or sell cheaply out-of-code, old dry yeast packets. Add a packet or two to the boil when you add the Irish Moss.
Yeast are horrible little cannibals...

They also package the stuff (brewers yeast) as a supplement at your whole foods or local GNC. I have even seen it packaged at Homeland Grocers in their Vitamins section and Ethnic Aisle.
Isnt nutrient just dead yeast??

IIRC some yeast nutrients are made by separating the inside of the cell from the cell wall. And obviously the inner-cellular stuff is the nutrient part... all the cell wall is cellulose and lignin.
just don't add too much yeast. We used to use Yeast extract to grow both yeast and bacteria in a lab I used to work in and it smells quite raunchy!
No, there is a good podcast on the BN with Chris White from What labs. I remember him saying that old dead yeast was not that great of a nutrient.
AKA Marmite or Vegimite.
Please correct me if I am wrong, but I was under the impression that Brewer's Yeast was a great source of B vitamins.
Marmite is made from (greater quantity first):
look at the amount of servings how big is this thing? cheers

I really dont know if it is or isnt. Lets assume it is. The next question is how much brewers yeast. Then lets say you get it amount right. What else comes along with brewers yeast? More of something you dont need?
I really dont know.
I think this article was really on to something with the use daily supplements. You make a very close approximate of what the yeast are missing, zinc and B.
