The groomsman bottle is, in design terms, the cousin of the bridesmaid bottle. Same number, same brand line, same crest, same wedding restraint. We are sometimes asked to add masculine ornament, a sword, a stag, a hammer, to differentiate the groomsman's bottle from the bridesmaid's. We discourage this. The wedding label is the household's label; both bridesmaid and groomsman gifts should carry the same mark.
One bottle, one note
Two bottles is the right count, one red and one white, matching the wedding's service. A hand-written note from the groom inside the case. We have seen customers attempt to make the groomsman gift larger than the bridesmaid gift, or vice versa; the asymmetry reads poorly later. Equal treatment of the wedding party is the right discipline.
Presentation
The same two-bottle wooden case as the bridesmaid gift. Same hand-tied twine. Same italic note. The visual treatment of bridesmaid and groomsman gifts should be indistinguishable. The wedding party as a whole has been part of the wedding; the gift recognizes the whole party.
The thank-you bottle
Some couples include a small third bottle, a half-bottle of dessert wine or a port, in a smaller compartment of the case, with a note specifically thanking the groomsman or bridesmaid for a single act during the planning. This is the right discipline if the customer wants to differentiate; the differentiation is in the small handwritten note, not in the label or the case design.
