Planning to brew today and have purchased LD Carlson Yeast Nutrient (Diammonium Phospate). Instructions on bottle say 1 tsp per gallon, I've got a six gallon batch, so it comes out to 1 ouce (6 tsp). And I believe the proper thing is to add this at 15 minutes with the irish moss (1 tsp).

I'm not set up to make yeast starters yet, so thinking maybe this is a helper.

Makes sense?

(I google these things, but there are varities of answers and this is the only board I care to register for AND seems to me the folks here are quite knowlegeable!) :D Thanks

Link to recipe, which I've worked hard to simplify:

This is only my opinion and I have nothing scientific to back it up just experiance. Yeast nutriants are great for starters because of the ratio of yeast to wort but in a full batch I have seen no positive effect. In your case I wouldnt even bother using it. There are plenty of sugars in your wort for the yeast to feed from.

:idea: You can make yeast starters without a stir plate or an erlenmeyer flask. You have to use a bit more volume, and wait a bit longer, but thats what planning and decanting are for.
 
I use Wyeast nutrient in starters and in full batches. It calls for only one half tsp for a 5 gallon batch. I add it at 15 minutes left in the boil. The vial was around $5, and it goes a long way. I am not familiar with the LD Carlson product.

Between nutrients, pitching like a pro with yeast starters, and my fermentation chamber, my beer is tasting better than ever.
 
Brew day complete, opted to just go as-is without nutrient.
Next time I think I need to figure a way to make a starter.
 
I also opted to save the expense of bottled water and brewed with my tap water (well), so we'll see about that. It tastes fine out of the tap, but I have no idea the chemistry of it.
 
RDWHAHB. I've never used anything other than tap water, have never used yeast nutrients and brew a pretty good beer. Like some posters, I don't see the benefit. I suppose if you were making a beer with a very high percentage of refined sugars you'd need it. I use straight light DME for my starters (and don't fret if I forget to make one), seldom add anything to my water and the results are satisfactory. Use these numbers for comparison, actual mileage may vary.
