Our Story


Our wines are sourced only from certified American Viticulture Areas in Texas & California.  In Texas, we source from the Texas High Plains AVA and the Texas Hill Country AVA. Our California wines are sourced from the Lodi AVA, Sierra Foothills AVA, Alexander Valley AVA, Monterey County AVA, and the very much sought after Mokelumne River AVA.


We picked these specific areas due to their very unique soils, climates, topography, and geographic locations.  Our farmers are passionate about their grapes and vineyards and their techniques in viticulture have been passed down from multiple generations.  Grapes of this rarity and quality are what you will find in every bottle of internationally recognized award-winning Sloan & Williams Winery wines.
