What is the minimum age for vines to be classified as 'Survivor' under the Barossa Old Vine Charter?

The classification of 'Survivor' vines under the Barossa Old Vine Charter specifically denotes vines that have reached the significant age of hundred years or older. This classification aims to preserve and promote the historical heritage of viticulture in the Barossa region, recognizing that vines of this age contribute to the unique character and quality of the wines produced.

While other ages may denote different classes, such as 'Old Vine' for those aged 35-80 years and 'Centenarian' for those aged 100 years or more, the 'Survivor' category emphasizes a longer-standing and resilient presence within the vineyard landscape. Such ancient vines are often valued for their low yields and complex flavor profiles that can enrich the regional wine offerings.
