Question:
Energizer provides essential minerals, nutrients and vitamins for yeast growth and metabolism. It’s used to help start slow or stuck ferments but can be added as insurance for a good ferment. It can produce salty off-flavours if used in large quantities. It commonly contains diamonium phosphate, nutritional yeast, and magnesium. Nutrient increases yeast activity. It’s also known as diamonium phosphate and is usually used to ensure a good ferment through an addition at the beginning of the ferment but like energizer it can be used for slow or stuck ferments. It can give an ammonia-like smell in large quantities. Usually energizer is the better choice since it contains extra goodies. — Dean Carriere Surrey, B.C.

Greetings all! What does yeast energizer do exactly? Since my homebrew shop sells both yeast energizer and yeast nutrients, I assume they are not the same thing. My understanding is that "nutrients" are usually some form of ammonia salts, which provide nitrogen that the yeast need to grow. "Energizer" is some sort of preparation made from dead yeast cells (yeast guts?).
Dead yeast, centrifuged out. Too bad energizer is so expensive. I suspect you could accomplish the same thing by using a 1/2 tsp bread yeast, boil it to death, then add some nutrient, then dump that into a stuck ferment. – Hide quoted text — Show quoted text – Under what conditions is it most appropriate to use a yeast energizer? If I had to guess, I’d say that the energizer is probably more "balanced", since by definition it contains all the stuff that yeast cells actually need to reproduce (because it’s made from yeast). But this is really just speculation on my part. (I’m not a microbiologist!) If I want to give my yeasties every opportunity to behave like ravenous maniacs, shouldn’t I always use a yeast energizer? Are there any negative consequences associated with the unnecessary use of a yeast energizer (such as off flavors or something)? Supposedly, all-malt worts should already contain pretty much everything your yeast needs to grow. If you’re brewing with a lot of non-malt adjuncts, or making wine or mead, adding nutrients/energizer may be advisable.
As an aside, I found another use for energizer. I had trouble getting my 1ml and 30ml starters to grow as fast as some I bought. I added energizer to my starters and got the results I wanted. I can start from a slant on Monday and by Saturday brewing have enough yeast to pitch 10 gallons of wort. | Tim Robinson | Lonely Web page.
