Jack London Vineyard Sonoma Mountain Zinfandel 2018

This vineyard is long recognized for its prized red wines and its Zinfandel is no exception. Since our first vintage in 1987, the Jack London Zinfandel has produced flavorful wines with excellent fruit and well-rounded tannins. Located on Sonoma Mountain with a southeasterly exposure, the climatic conditions and long, cool growing season of this viticultural area create complexity and balance in the fruit. The influence of the vineyard’s red volcanic soil and the fruity characteristics of the grapes combine to produce an outstanding, very distinctive Zinfandel.

Winemakers Notes

The 2018 vintage was mild and dry allowing extended hang-time without worry of rain or desiccation. The Zinfandel was picked October 16th and fermented on the skins for 15 days. The finished wine was then aged in French and American oak barrels, 40% new oak, for 18 months.
