Yeast Nutrient Quantities

[WinterWarlock]

So the LD Carlson yeast nutrient (containing diamonium phosphate and urea) suggests using 1 tsp. per gallon of must. I noticed MoreBeer sells straight DAP and they are recommending 1/2 tsp per 5 gallons. That's a serious difference for what I'm assuming is a pretty similar product. Should I stick with the LD Carlson recommendations, despite the fact that I'm working with wort, not must? I'm currently making a starter and want to avoid overdoing the nutrients. Thanks, amigos!

High levels of DAP is toxic to yeast; I would avoid using it in a starter.

For beer, I think Wyeast nutrient or White Labs Servomyces are better choices because they supplement zinc. ... Plus Fermaid O as needed for difficult fermentations.

I use 1/2 - 1 tsp in 5 gal depending on the gravity of the wort. The first time I used it I used 5 tsp per the directions and my FG ended up lower than usual

All, are there specific types of beer where yeast nutrient is more or less desired?

In all the beer I've brewed I've never used yeast nutrients. I've learned to use them in mead though lol.

Thanks for the info! Seems every "video" of brewing involves a "couple tablets" of nutrient. I'm very new to the whole process and trying to learn as much as possible and not brew crappy beer. I don't need to be an expert, simply competent

Beers with added sugar in particular benefit from nutrient supplementation.

Adding a good yeast nutrient (i.e. not DAP) provides a safety net to avoid fermentation problems, regardless of the beer.
