Yeast Nutrient

[Morebeer4me]

Yeast nutrient I use (wyeast) is 2.2g per 20 odd litres. Add 10 mins before flameout.

Hi Manticle,
Is it ok to add old kit yeast at 10min for biab no chill , cubed
Cheers

I've done it a few times with old packs of Coopers yeasts, don't know if it made much difference.
I always use yeast nutrient where there are non-malt components in the recipe such as rice, maize, sugar or maltose syrup as they are "empty calories" as far as the yeast is concerned.

For all malt brews I generally use YN (the brown stuff from Sponsor) but sometimes forget

Does anyone know what is the recomended dosage for adding nutrient to a starter?

I tend to add a 'smidge'. I would estimate this to be a few grams worth. I use DME in my starters or wort prior to hopping (Plenty of nutrient in there as it is).

Which nutrient wolfman?

I use wyeast nutrient - dosage for that is 2.2g per 5.5 US gallons (19-20 L) so depending on the size of your starter, you could work backwards from that.

I make my starters from wort that has already been dosed with nutrient (taken from the kettle post boil) but if I ever add to anything other than my wort, it's a smidge as per Raven (although I'm not sure if he uses US smidges or UK imperial smidges).

The yeast book says 1/8th of a teaspoon for 2L

I have just used some Wyeast nutrient in a starter and I have noticed a strange stale smell. Anyone smelt a difference in their starter when using Wyeast nutirent?

No need to reply. I have just tasted it and its rank!
Tossed it out and now making another. Must be some sort of infection. I did notice some black spots on the bottom, not sure if its from the dregs of my last runnings or something growing

Some/many yeast nutrients include DAP (Diammonium phosphate) which can smell pretty horrid (ammonia) when added to small volumes (especially if its heated) - but you'd have noticed that when it was first added, not after it had fermented out.
