No guy should have to deal with a sub-par bar, so make sure your groomsmen can drink in style with bar accessories for their home bar area. Even if he's fully stocked up with top shelf liquor and enough mixers to keep you in cocktails until the honeymoon's over, most guys don't think about bar accessories like coasters, decent martini glasses, beer can caddies and other pieces that might make the future wife actually join you in your get-togethers one of these days. You can even get a groomsman something as simple as a personalized sign to mark the area as his relaxation zone.
Bar accessories don't have to be fancy, but if your groomsman hitting the bottle means a good 1991 Riesling, then give him impressive bar accessories like wine presentation cases, special cork screws, and top of the line accessories. No matter what your groomsmen drink, you can find great bar accessories to give them as gifts. Bottoms up!
