Old Vines
Vieilles vignes — why vine age matters and why the term has no legal definition
Why Age Matters
Grapevines grow more slowly and produce fewer grapes as they age. This reduction in yield concentrates flavor compounds in the remaining fruit. Old vines also develop deeper root systems that access water and nutrients from lower soil layers — making them more drought-resistant and more expressive of deep terroir.
What Counts as Old
There is no universal legal definition. Common benchmarks: - 20–30 years: Some producers use this as their threshold - 50+ years: Widely accepted as genuinely old - 80+ years: Rare, particularly in Europe after phylloxera devastation - 100+ years (pre-phylloxera): Extremely rare; found in some pockets of Australia, Chile, and parts of Spain
The Phylloxera Context
Most European vines were destroyed by the phylloxera louse in the late 19th century and replanted on American rootstock. Truly old European vines — pre-phylloxera — are exceedingly rare. "Old vines" in Champagne, Burgundy, or the Rhône typically means the oldest vines on a particular estate, not pre-phylloxera survivors.
Skepticism
Because "old vines" is unregulated, it is sometimes used opportunistically. The term is more meaningful when combined with specific vine age data and evidence of reduced yield.
