Old vines: why they matter so much in natural wine
"Vieilles vignes" — two words often seen on wine labels, sometimes incorrectly. In conventional winemaking, it is sometimes a marketing claim without real substance. In natural wine, it is an agronomical and oenological reality that profoundly changes the wine in the glass. An old vine is a vine that has had time to understand its terroir — and that states it clearly in the wine it produces.
How does a vine age?
A vine is planted from a graft (a rooted cutting). In the first few years, it produces plenty of grapes but of mediocre quality — the vine is in its growth phase and has not yet had time to root deeply. Most winemakers do not use grapes from the first 3 to 5 years for their quality wine.
Starting at 15-20 years old, the vine begins to find its rhythm. Yields drop naturally. Between 40 and 60 years old, we start to speak of "old vines" in most French regions. Beyond 80 or 100 years, we speak of "centenarian" vines — a rare treasure, increasingly threatened by diseases and economic removal.
In France, there is no legal definition of a "minimum age" for using the "old vines" label. A producer can technically put it on a label for 20-year-old vines. This is one of the gray areas of wine law. In natural wine, the term is generally used with more rigor — and often for vines 50 to 100 years old.
What changes with age: the roots
The primary phenomenon is that of the roots. A young vine has superficial roots — it draws its nutrients from the top layers of the soil. An old vine has roots that can reach 5, 10, or even 20 meters into the soil and subsoil. These deep roots reach geological layers inaccessible to young vines — minerals, water reserves, and a diversity of micro-elements that are subsequently found in the grape and the wine.
This is what is called the "minerality" of a wine: that impression of cold stone, flint, iodine, or chalk perceived in certain old wines. It is not solely due to the deep roots — the terroir also counts for a lot, as we explain in our article on terroir in natural wine — but old vines amplify it considerably.
Naturally low yields
An old vine produces fewer grapes than a young vine. This is not a defect — it is precisely what gives it its value. With 15 to 25 hectoliters per hectare (compared to 50 to 80 for a conventional vine in full production), each grape concentrates more sugar, acidity, tannins, and aromas. The result in the glass: a denser, more complex wine with a length on the palate that wines from young vines do not achieve.
For the natural winemaker, these low yields are a blessing. They do not need restrictive pruning to artificially limit production — the vine does the work itself. And fewer, better-sorted grapes mean fewer risks during fermentation and a wine that is easier to vinify without additives.
A natural resistance to disease
Over the decades, old vines have developed a resistance to diseases and pests that young plants lack. Their plant immune system is more robust — they endure difficult years (frost, mildew, oidium) better without needing intensive chemical treatments.
This is a major advantage in organic and natural viticulture: more resistant plants require fewer interventions, which is consistent with the natural winemaker's philosophy. An old Carignan or Grenache vine in the Languedoc — a warm and dry region — can survive difficult years with a serenity that nothing can reproduce artificially. Our BIB wines from the Languedoc often offer vintages from these historic old vines.
Grape varieties that benefit most from aging
All grape varieties age, but some benefit spectacularly from great age:
- Carignan: a long-despised variety, it reveals itself to be extraordinary on old vines. Its naturally rough tannins refine with age, and its concentration of black fruits, spices, and licorice becomes impressive. It is the star variety of the centenarian vines of the Languedoc and Catalonia. To learn more: our article on Grenache, Carignan, and Cinsault from the Languedoc.
- Grenache: on old vines, it gains in complexity and minerality, losing the sometimes "jammy" side of young vines in favor of finer and spicier profiles.
- Chenin Blanc: old Chenin vines in the Loire are among the most precious in France. They produce whites with exceptional tension and longevity. Our article on Chenin Blanc in BIB discusses this in detail.
- Gamay: rarer in very old vines, but 50-60 year old Gamays on the granite soils of Beaujolais produce wines of a complexity and depth surprising for this variety.
The threat to old vines
Old vines are under threat. During the decades of intensive viticulture (1960s-1990s), thousands of hectares of old vines were pulled up — low yields were not profitable in a mass-production logic. Removal was even subsidized by the State to modernize farms.
Today, several associations campaign for the preservation of old vines: the Registre des Vieilles Vignes, the Association des Vieilles Vignes, and regional labels. Many natural winemakers participate in this effort — convinced that these centenarian vines are an irreplaceable heritage. When you choose a natural wine from old vines, you participate in their preservation. This is one of the dimensions of the natural commitment we share at LET IT BiB.

Frequently asked questions about old vines
At what age is a vine "old"?
There is no legal definition in France. In practice, serious winemakers use the "old vines" label starting at 40-50 years old. Some regions or associations have internal rules (Alsace Grand Cru, for example, recommends a minimum of 30 years). In natural wine, transparency is generally the rule — if the winemaker indicates an age on the label or technical sheet, it is generally reliable.
Is a wine from old vines always better than a wine from young vines?
Not necessarily "better," but different in a way that is often perceived as superior. A wine from old vines is more complex, more concentrated, and has more depth. But a well-vinified wine from young vines can be delicious — lighter, fruitier, and more accessible when young. Both have their place. For a daily wine to drink over 4-6 weeks in a BIB, a well-made wine from young or middle-aged vines is often more suitable than a great wine from old vines.
Is the BIB format suitable for wines from old vines?
Yes, for wines designed for consumption over a few weeks. The great aging vintages from old vines (a centenarian Carignan from Faugères, for example) often remain in bottles for 5 to 15 years of aging. But many old-vine wines are produced in an accessible style — fruity, ready to drink — and lend themselves very well to the BIB format. The airtight bag preserves their complexity glass after glass.
