I just found a bottle of it in the back of my freezer and it must be at least 3 years old. It smells normal and a taste on my finger tasted normal. It does have ice built up within the bottle...perhaps the water separating from the alcohol?
There is no expiration date but it is 50 proof...safe to drink?
Many types of alcoholic drinks do have expiry dates. It depends upon the type of the drink. Spirits generally do not due to their higher alcohol content but all beers and many wines are only safely drinkable for a fixed period of time.
Checking back in.....I was wrong, it's 100 proof (so prob def safe). But, it was SO STRONG. Couldn't even do a shot. Usually I can do double shots of anything, but not from of this "aged" bottle! lol The little sip I had was enough to clear out my sinuses. I threw it out, but maybe I could've saved it to use as paint thinner.
Sounds like a challenge to me. In the name of scientific experimentation, I suggest that you try it and report the effects of ingesting old shnapps. I'm guessing they will be almost identical to the effects of ingesting new shnapps.
