Does yeast nutrient contain gluten?

Hey guys,

I've searched on Google, but I can't find a definitive answer; does yeast nutrient contain gluten? We keep a gluten-free house, as my wife and son are HIGHLY allergic, and I'd hate to make a wine she couldn't drink.

Thanks!

Boil some GF dry yeast and use that.

Thanks for the quick response, David. I'm still a bit of a noob. Can I use any GF dry yeast from the store (we have a Wegman's nearby that has a full GF baking section) or do I need to use brewing yeast? What do I do after I boil it? I've never made it from scratch before.

My last batch of wine (apple wine) got on fine without yeast nutrient, but this batch (local blackberries) started off slow and went downhill from there.

Thanks!

Yeast nutrient is di-ammonium phosphate. As far as I know, nothing else is added to it.

Thanks, Doc. David, can you tell me (or can you point me to a thread that does) what to do with the boiled yeast? I understand of course that that would kill the yeast, thereby providing hulls and such for the yeast in the wine to feed on. How long do I wait, etc?

Thanks!

Dead yeast are the best source of nutrients for yeast. Brewing dry yeasts are grown in GF media, unlike most liquid yeasts, so by boiling some dry yeast (5-10 minutes) you provide everything your selected yeast needs for growth.

(I wasn't around last weekend.)

Awesome, thanks for the hand holding. Do I have to wait any special time after boiling, or just until it cools down?

YEAST NUTRIENT IS TOTALLY INORGANIC!!!!!!!!!!!!

Why are you concerned about it?
