A glass of wine with your DIA wait?

A wine-tasting business wants to open a location at Denver International Airport, as DIA aims to improve its concessions program.

Vino Volo, a San Francisco-based company with wine-tasting shops in other U.S. airports, said it has been in discussions with DIA, though nothing is definite. Concessions are typically competitively bid.

"We think they have a good concept," said Lisa Torres, who manages concessions at DIA.

Vino Volo opened its first airport shop at Washington's Dulles International in September 2005 and has shops at Seattle-Tacoma, Sacramento, Baltimore/Washington and New York's John F. Kennedy airports.

The company plans to open ``several dozen'' more airport stores in the next five years. The 1,000- to 2,000- square-foot stores sell wines from around the world in tastes and tasting flights, by the glass and by the bottle.
