Wine wishing well?

Has anyone attended or hosted a shower that had a wine wishing well? Basically instead of the traditional wishing well with kitchen gadgets and trinkets - guests are asked to bring a bottle of wine. How did this go over? I was invited to one a few years ago that had a cute poem insert about it & the bride was thrilled with it. Anyone have any ideas for wording this on an insert with the shower invite? I have a lot of friends getting married this year and we're trying to switch it up!
