Happy Canyon is Santa Barbara's warmest AVA. Sheltered from marine winds by a turn of the coastal mountain range on the eastern fringe of Santa Rita Hills, its inland climate is markedly warmer with less diurnal variation in temperature. Happy Canyon is also geologically diverse. Its central elevations are typified by serpentine, a magnesium silicate and iron oxide composite, and chert, a crystalline quartz. Degraded by erosion, they are interspersed in clay loam topsoils. Tommy Town Vineyards lies in a zone where these stony loams cover a clay stratum that curtails vigor and hydration. The magnesium silicate content limits yield while enhancing terroir expression and varietal elegance. All these factors make Happy Canyon an optimum mesoclimate forBordeaux varieties.
Between 2006 and 2007, Tommy Town's vineyards were planted to the first plots, totaling just over twelve acres, of the full spectrum of red Bordeaux varieties. They were augmented in 2010 by an acre of vines on a property in Santa Ynez soon to include a visitor center. In 2011, eight additional acres ofCabernet Sauvignonwere planted on a southern extension of the Tommy Town estate, as well as nine acres of Sauvignon Blanc and Merlot just west of Tommy Town.
