There's an 1800's random papal decree
that you can add alcohol to the Eucharist for the purpose of stopping it from spoiling as long as it's less than 18% .. so I suppose sherry would fit that. I've never been in a Cafflick church that didn't use diluted wine though. But then I've got quite limited experience.

I've only been in two catholic churches.
Still managed to catch AIDS off that priest though.

Our church never used pre-diluted wine
although during the mass the alter server would take up two small jugs, one of wine and one of water. All of the wine went in and a teeny weeny amount of water. I never understood the reason for that.
