I manage part time at a wine bar here in Houston, Uptown Park's The Tasting Room. We generally sell 12-15 wines by the glass. We break the choices down into red, white, sparkling, dessert, and a usually a couple of Sommelier Picks.
When describing a wine you generally want to talk about 3 things:
- Body - light, medium, full
- Sweetness (or lack of) - sweet, off-sweet, off-dry, dry
- Flavor - usually fruits but can include many other flavors too like herbs and spices too
