The Santa Ynez Valley AVA is one of the major wine growing regions in Santa Barbara County, spreading from the eastern edge of Lompoc on the western end of the Valley, to the far side of Happy Canyon on the eastern end of the Valley.
The Santa Ynez Valley has many different micro-climates within its boundaries, starting with a cool ocean influence in Lompoc and getting progressively hotter as you move inland. This enables different varieties of grapes to flourish, and therefore a diverse lineup of wines.
There are four associated appellations within the Santa Ynez Valley: Sta. Rita Hills, Ballard Canyon, Los Olivos District, and Happy Canyon of Santa Barbara.
