Alta Colina, as the name suggests, is an estate located high in the hills. Alta Colina’s 31 acres of organically-farmed vineyards are at 1,800 feet above sea level in the Adelaida District of Paso Robles. The estate was founded in 2003, when Bob Tillman founded the 130-acre property and decided to turn his winemaking hobby into a commercial venture. Having spent 35 years working as an engineer by day and making wine at night, Tillman and his family acquired the property and planted vineyards. They started selling wine in 2009 and built an estate winery in 2014. Tillman runs the estate with his daughter Maggie and makes the wine with help from his cellar master Paul Lopez. All wines are estate grown and produced. Alta Colina focuses on red and white Rhone style wines. The wines have won ratings in the mid-90s and reviewer Jeb Dunnuck describes Alta Colina as a “terrific estate.”
