if you're not on fluid restrictions, ie at ESRD (and at 17% doesn't sound like it) then it's fine. Wine has less potassium than beer so from that perspective it's also OK, though if you're just having a social drink I really don't think it's an issue. My neph never really discussed alcohol as being an issue.
When on fluid restrictions then, as KS says, spirits are "better" from the point of view of a "bang" for less fluid - ie: a 30m shot of a clear spirit like vodka is much better than a beer, which is 10x the volume, and has potassium to boot!
In pure terms the clear spirits would be the "best' since they don't have potassium or phosphates(that I'm aware of).
A glass of wine is fine. Heck I had some French Champagne on the 14th to celebrate Bastille Day. Oooh La La!
Hey, life's for living I reckon - and in moderation there's no problem. Plus my fluids were actually down when I went to D (due to dehydration and it being a part diuretic) so it was all good
