How Old Does the Zinfandel Vine Have To Be?
The accepted standard is 50 years or older. This number is agreed upon by notable organizations like The Winegrowers of Dry Creek Valley and The Historic Vineyard Society. The Historic Vineyard Society holds old vine Zinfandel to an even higher standard, requiring that the grapes are also sourced from a currently producing California wine vineyard, and at least ⅓ of the existing producing vines can be traced back to their original planting date.
This standard is not mandatory or enforced, so you will sometimes find wines that are made from younger vines using the term “old vine Zinfandel”.
What makes Old Vine Zinfandel Unique?
Most people in the wine world believe that old vines make better wine than new vines. As a Zinfandel vine ages, it cultivates deep roots and produces less grape bunches. This creates a more intense flavor profile (think crushed cherry, blackberry, raspberry preserves, and blood orange). These old Zinfandel vines also have thinner leaves - which lets the grapes absorb more sunlight.
The end result is a wine that has soft, concentrated fruit and tannin with a good amount of acidity (some call that a “well-balanced” wine). An old vine will produce a very different wine than it would have been able to produce in its younger years. We like to think of it as the vine perfecting its craft as it gets experience, just like a winemaker!
