Do yeast nutrients expire?

Post by mrbean »

Long story short I have a stuck sugar wash and I suspect it was caused by the nutrients I used. I have a bottle of Fermax that I've used in the past with good success. I've had this particular bottle for some time (a year or more perhaps). When I opened it up most recently it had a very strong ammonia odor along with a slight rotten smell. IIRC, when the bottle was new is smelled like fish food (the little flakes you would feed to a goldfish).
The bottle doesn't have an expiration date printed on it and the manufacturer has no information on their website. Did this stuff ruin my wash? SG is now around 1.025 and has only dropped 10 points in the last 5 days.

Edit: Also, is it worth trying to re-start this wash or should I just cut my loses and distill it? Or, I might just drink it as is. It's pretty darn tasty.
