Thorn Hill Vineyards tasting room in Lancaster is a must if your trip includes any wine! While the Thorns live in Lancaster, their grapes are grown in three areas of California – Lake, Sonoma and Napa. Whether you like white or red, or something in-between, these wines are our absolute favorites and the standard to which we judge all other reds!! We are charter members for the last 11 years. They offer lots of events that are open to the public.
