Rockpile Jack's Cabin Vineyard Zinfandel is a hugely powerful and concentrated red wine from Sonoma, located on the West Coast of the United States. The grapes are sourced from the high elevation Jack's Cabin Vineyard, located in the Rockpile appellation, which is known for its high elevation and rocky soils, resulting in concentrated and complex flavors. The winemaking process involves careful selection of the grapes, hand sorting, and aging for around 14 months in oak barrels prior to bottling.
