The winery says:
Taking it back to when Zin was easy drinking and no thinking! Dry farmed, head trained, gnarly zinfandel vines farmed by the Tollini family that were planted in the 1970's in the heart of Mendocino are no bull! Easy tannins and bright natural acidity carry the layers of juicy fruit and zesty spice. Whether having a dinner party, barbecuing, relaxing after work, or on a weekend getaway, there's never a wrong time to make it old school.
This wine is confirmed as vegan by the winery.
