Splash wine colors all over the room, forming the visual palette. You may wish to choose at the outset whether you prefer a cool, light palate inspired by white wines or an intense, opulent palate inspired by red wines. Paint the walls a golden-pear yellow, like a fruit wine, and accent with light-colored wood and shades of white. Or, if you like decorative intensity, paint the walls burgundy and use dark wood and accents of aubergine.
Pick furnishings that evoke wine or the wine-making process. For example, spread out a plush deep-purple rug that welcomes bare feet, paying sensory homage to the barefoot grape-stomping of old-fashioned wine making. Construct or purchase a light fixture woven with dried grapevines. Put out chairs made of wood reclaimed from an antique French barn. Don't forget a wine rack and a few bottles. Place a music station in the room so you can play your favorite relaxing music while you hold wine tastings or entertain guests.
Hang art on the walls of the front room that depicts wine or is somehow related to wine. You don't have to adorn the room with a bunch of still-life paintings of grapes and wine glasses. Frame reproduction posters of fin-de-siecle Parisian cafe advertisements or hang a single Old-Master-style painting of a vineyard in Bordeaux, France. Landscape photos of famed wine-producing regions from Chile to New Zealand to Napa, California could also enhance the ambience.
Sprinkle wine bottle accents throughout the room in subtle ways. Cut the necks from wine bottles and etch them with patterns or words -- such as words forming a line from a poem -- and line them up on a windowsill. Use wine bottles as vases, each holding a single long-stemmed rose. Wine bottles can also be used as incense holders. Use tumbled wine-bottle glass to make a mosaic for the top of a cafe table.
