The church my mom took me to as a kid usually had the option to take a very small (single sip) cup of grape juice instead of the same size small cup of wine during the communion part of the service.
But sometimes on rare occasions I went to a service outside the church proper (for example, one was to my uncle’s house where my grandmother was dying of cancer) and usually for that kind of thing they only brought the wine, so I had to take some.

I was mostly joking about it putting me off religion (plenty of other factors there). But it really did taste extremely nasty, and every time I’ve tried alcohol since then reminds me of it, so it might really be part of why I don’t like alcohol.
