[OSM-talk-be] Proper tagging of wine or champagne bars

[Yves bxl-forever]

Hello folks,

This case has been puzzling me for a while.
A few establishments in Brussels specialize in serving only one type of drinks: champagne, wine, beer…

amenity=bar seems appropriate but does anyone know what tags one could use to inform about the kind of beverages being served?
There are a few taginfo entries with cuisine=wine or cuisine=wine_bar but I wouldn’t advise this.
As a last resort, the description key can contain the information, but perhaps there are more useful ways to convey it.
Any suggestion or hint?
