Yeast Nutrient in a starter??
 
Has anyone used the White Labs WLN1000 Yeast Nutrient? It says to add 1/2 tsp per 5 gallons, but if I add it to a starter, do I add a full 1/2 tsp based on the overall beer volume, or do I scale back based on the starter size?

I've not used the White Labs stuff, but I assume the Wyeast product is similar. I'm not terribly precise about it, but you want to scale it to yeast growth, not to total volume. In other words, I'd put less than I would in 5 gallons, but not twenty times less. Put a quarter teaspoon. I can't imagine that it would hurt the yeast if there were more than it needed in there (within a reasonable degree).

Ive been adding about 1/3 tsp of yeast extract from wyeast per 2L , I use oxygen injection via a stone and disposble tank. I get excelent results even with the mason jars of washed yeast that I have stored in my fridge.

i only use yeast starter to fresh yeast, not to a starter, per instructions on my bottle

let me try that again.... i only add yeast starter into a wort where i just pitched yeast. i pitch yeast, dump in yeast starter, and let it go

I always toss in a pinch of nutrient (Wyeast) when boiling the starter wort. This is the amount I use for a for a 2 liter starter. a couple of pinches for a gallon starter. I always get excellent results.

I usually use about a gram or a half gram to my starters.

I scale the amount of yeast nutrient to the starter size. For a 1 liter starter I use 0.2 grams. The actual calculated amount is 0.12 grams but I can't get that accurate so I just round up to 0.2 grams.

If you add nutrient to your starter, do you add more nutrient to your wort at pitching time? I haven't been doing this. I figure the yeast get their nutrients from the starter, then get a big dose of oxygen at pitching time, and they've got everything they need to start fermenting, but maybe I'm wrong.
