So How old is Old?
Also dose It matter where the vine is planted?
-->Old Vine Zin:
Hi Peter. It's generally accepted that 50+ year old vines are considered "old" and 80+ are "ancient." Never heard anything about a vine's location determining "old vine" status.
Actually from my experience there is no "generally accepted" definition! Back when I first put "Old Vine" on my bottle I was referring to the old field of vines that my family purchased in 1972. For a long time it was believed they were planted in 1906 but I have come to learn that they could have easily been already producing for 10 years before 1906 -interestingly, a winery, a few hundred feet away, was destroyed by the 1906 earthquake! So for my wine, "Old Vine," means over 100 years old. I have gone to ZAP tastings and tasted some very poor stuff labeled "Old Vine" when I asked one proprietor how old is old he told me about / almost 20 (so 16?)!
...But growing conditions are equally important for a great Zinfandel! at our site we have a shallow light sandy loam and are still dry farmed so growth & production is very limited, the fruit is very intense, and the vines need a lot of care to just to survive the dry season. Two miles away the elevation drops 30 feet, the soil becomes a bottomless black clay and the water table is always within reach of the vine roots so the vines are huge, vigorous, produce a heavy crop and there is a Zinfandel Vineyard about the same age as ours... Lets' just say the fruit & resulting wine are not of similar quality. I have considered discontinuing the term because it has been so abused!

Peter, I definitely agree with you regarding the overuse of the term "Old Vine" and even "Ancient Vine." I've seen that on many labels, only to read the back label (small print) to discover the wine is merely "inspired" by old vines, or "contains a percentage of old vine juice." Yeah, like .001%, I assume.
In Australia, they have the Barossa Old Vine Charter. It breaks down the designations this way:
Old Vine: equal or greater than 35 years of age
Survivor Vine: equal or greater than 70 years of age
Centurion Vine: equal or greater than 100 years of age
Ancestor Vine: equal or greater than 125 years of age
Here in the USA, Joel Peterson recommends vines be classified this way:
Young: 0 to 10 years
Middle: 10 to 50 years
Old: 50 to 80 years
Ancient: over 80 years
I would like an official designation in order to protect the term "old vine" from being too watered-down (pun intended). You guys have certainly gone the extra mile in the past by splashing "Planted in 1906" across the top-left corner of your front-label.
My simple take on the issue is to set "old" at 50 years and "ancient" at 80. Then adopt the same requirements used to define a varietal in the USA: 75% of the juice must be from that grape. As a result, I could pick up a bottle of "Old Vine Zin" and I would know (trust, hope, fingers-crossed) that 75% of the juice was from Zinfandel vines 50 years or older.
But that's just my take -- I'm in North Carolina and you've got Zin vine splinters in your hands. What do you think, Peter?
