Del Frisco’s Philadelphia has introduced an exciting new luxury wine program dedicated to rare, reserve wines so that customers can sample some of the finest vintages available.

The brainchild of the restaurant’s sommelier, Jeffrey Mayfield, the program depends on the use of a “Coravin,” which is a wine preservation tool that lets servers and sommeliers pour a glass of wine without actually opening a rare bottle. Using a needle that goes directly through the cork, the Coravin pumps wine into the glass and then lets the cork naturally reseal. Thanks to the Coravin, wine poured in this way can last up to two years.

According to Mayfield, the goal of the program is to “offer our wine-loving customers a way to enjoy a rare, reserve glass of wine without having to buy the entire bottle” — rather than order an entire bottle of $495 Opus One 2010, wine enthusiasts can try a glass for just a portion of the bottle’s cost.

The price range, naturally, is quite wide for this type of program, ranging from $35 for a glass of Louis Latour 2008 Chardonnay to $125 for the aforementioned Opus One, but Mayfield explained to Drink Philly that the prices are carefully determined to represent what one glass would cost when the bottle is divided into 6 ounce pours.

The exact wines on the reserve by-the-glass menu will change and develop as Mayfield continues the program, but he does plan to keep 8 to 15 wines on the list at all times.

Head to Del Frisco’s now to try some of the world’s finest wines without committing to an entire bottle — even though the wines are so good that you just might want to.
