I originally thought you were talking about home brewing custom content for TTRPGs, but alcohol is cool too.

I use the same brand of pomegranate juice to make grenadine syrup, and I always have so much juice leftover that I don’t know what to do with (except drink of course). I think you have inspired me. Any tips for a potential first time fermenter?

Unfortunately this is the difference between illegal and unethical, and I don’t gather that HP cares much about ethics. Hopefully right-to-repair laws will cover these cases in the future too.
