Fermax Yeast Nutrient
« on: February 14, 2013, 12:28:39 PM »
I bought some Crosby & Baker Fermax Yeast Nutrient and on the bottle it recommends to use 1 tsp per gal, however I've been told to only use 1 tsp per 5 gal.  Which is correct?

Also, at what point in the boil is it best to add it?

Does the it say 1 tsp/gallon of must. That would be the wine dosage.

For beer maybe a 1/2 to 1 tsp towards the end of the boil.

I don't think it specifies must/wort, but it is sold for both.  I'd agree 1tsp/gallon is a lot. Unless they've added some filler, which I doubt, I'd go with 1tsp/5gal.  Wine must has fewer nutrients than wort, which is why you'd use less.

Yeah, it doesn't specify must/wort on the bottle.  I'll go with 1 tsp/5 gal.  Thanks!

Adding at the end of the boil.....like w/in the last 15 min, 10 min, or 5 min?

Any would be fine, use 5 if you wish.

It's for the yeast, so it doesn't really matter when you add it. I don't think boiling hurts it, so you could add it beginning, middle, end of boil, in the fermentor. Same effect. Just pick what is convenient for you. I like to throw nurtients, irish moss, etc in the bowl with my flavor hop addition if I'm using one. That way I can't forget it.
