How long must a vine be to qualify as 'Old Vine' under the Barossa Old Vine Charter?

Under the Barossa Old Vine Charter, a vine must be at least 35 years old to be classified as 'Old Vine.' This designation is significant because it highlights the unique characteristics and qualities that older vines can contribute to wine production. Vines that have reached this age are generally considered to have deeper root systems, which can draw more complex flavors from the soil and contribute to the overall quality of the wine. This age requirement is also essential in preserving the heritage of the region, as many old vines in Barossa Valley are linked to the history and traditions of Australian winemaking.

Older vines, particularly those that are 35 years and above, often yield fewer grapes, which can lead to more concentrated flavors in the resulting wine. Thus, the 35-year threshold under the Charter serves both to protect the legacy of viticulture in Barossa and to ensure that consumers are aware of the potential quality associated with wines sourced from older vineyards.
