Aaron produces wines from Paso Robles, the warm, mineral-rich corner of California's Central Coast known for bold red varieties. The winery focuses on Rhône and Spanish grapes—Petite Sirah, Syrah, Grenache, Mourvèdre, and Zinfandel—varieties that thrive in the region's diurnal temperature swings and gravelly soils. Sand & Stone, a blend of Petite Sirah, Syrah, and Grenache, anchors the portfolio, joined by Trespasser, a four-grape blend that adds Mourvèdre to the mix, and Citizen, a Petite Sirah and Syrah pairing. These wines have been assessed by Wine Enthusiast and Wine Advocate.
