Yes, this Rutherford-based agricultural operation sells wine. But what sets Round Pond apart from just about every other Napa Valley winery is its olive mill. Through tours and tastings, visitors get an intriguing behind-the-scenes look into the world of olive oil. Tours wind through the olive orchard while guides explain the process of harvesting. Tastings take place inside the mill; you smell the oil first and then taste it with different vegetables, breads, meats, and cheeses. With the exception of a few reserve samplings, most wine tastings at Round Pond occur on the second-story tasting lounge and covered terrace, a space with panoramic views of the estate and the palm-lined driveway. To combine both sides of the house, try the Il Pranzo tasting, which includes wine and food on the winery side and olive oil and food on the olive mill side. What’s more, for an unparalleled winery visit, book a spot at the weekly garden-to-table brunch, a four-hour experience that includes a tour, a harvesting session in the winery garden, a cooking class, and an farm-to-table meal served in the garden itself.
