Bogle Vineyards Old Vine Zinfandel 2015. Zinfandel grapes were first planted by European immigrants in the early 1900's and are still producing today. The fruit produces distinctive wines of extraordinary flavor and intensity. In selecting grapes from these old vines, we have handcrafted this wine that displays intense blackberry, black cherry, and raspberry flavors, wrapped in a smooth blanket of vanilla and oak. This wine contains 14.5% of alcohol by volume.
