The people are always so friendly here. Wines are always great. The wine staff is very open to teach you about wine. They're not pretentious as a lot of the wineries are up in Napa. Quit refreshing. Located in picturesque St. Helena, Merryvale’s historic building was the first winery built in the Napa Valley after the repeal of Prohibition in 1933, and has become a favorite destination for visitors to the valley. Merryvale Vineyards inviting cellar is ideally located in the heart of Napa Valley within easy walking distance of shopping in downtown St. Helena, across from the casual eatery Gott's Roadside, and next door to world-famous Tra Vigne restaurant.
