(WSJ) - A small group of women walked through Merlot grape vines on a breezy morning last week headed to a sprawling lawn for one of Wölffer Estate Vineyard’s newest offerings—yoga.

Wölffer, based in Sagaponack, N.Y., has been best known for the annual run on its rosé at Hamptons wine stores during beach season. The winery started offering a few on-site yoga and boot camp classes last summer, and they were so popular that it increased the number of fitness sessions to six per week this year. “Sundays on the Terrace” with pastries and Bellinis coincides with the ‘Morning Flow’ class.

“A lot of people go to yoga … and come back and pick up their wine for the weekend,” says winery co-owner Joey Wolffer. She calls the program a “no-brainer” because the winery’s expansive property can accommodate workout-seeking visitors.

A number of U.S. wineries have begun offering fitness classes including yoga, Pilates and boot camp-like training, usually followed by wine tastings. Wineries hope to tap into a fitness crowd and attract wine lovers who want more than the traditional tasting and a cheese plate.

Exercise and alcoholic beverages aren’t typically thought of as going hand in hand. But wine has a reputation as a relatively healthy beverage choice and people often feel they deserve a treat after exercising. An offering of yoga with refreshing wine and small bites makes a workout “not something you have to do, but something you get to do,” says Cate Ritter, a nutritionist based in Pebble Beach, Calif. Drink some water after yoga and before wine, she suggests.
