About the Winery
Grounded Wine Co. is the label of Josh Phelps, a Napa native raised in a winemaking family. He learned wine through college, selling wine, working harvests and making wine with his father, Chris Phelps, and he started Grounded to build on that family legacy while connecting his own generation to wine country.
Grounded makes wine from sustainable vineyards across California and Washington, working with trusted farmers and childhood friends. The range includes Grounded by Josh Phelps, a Sauvignon Blanc under the same name, Space Age Rosé, Landform, Steady State and Public Radio. In 2022 Wine Spectator called Grounded a relatively new name among reliable sources for quality Napa Cabernet.
Grounded sells online, through retailers listed on its Find Wines page and through its mailing list. Its website lists an Oak Avenue address in St. Helena, but its visit page is not active and there is no tasting room. Since Grounded does not host, the day below takes you to three sought-after estates nearby that do.
Tasting Fees
Grounded Wine Co. does not offer tastings.
Tasting fees as of September 2026. Wineries set and collect their own fees, and they change from time to time.
