How Is Armagnac Made? From Vine to Bottle

Armagnac is made by distilling a light, unsulfited wine over the winter, usually in a copper column still called the alambic armagnacais, then aging the clear spirit in oak casks for at least one year. Distillation must be finished by March 31 after the harvest, and the aging clock is counted from April 1. Once the spirit is bottled, it stops aging.

Every OADE release is a single cask, so each step below shows up in what we bottle. Most of the rules come from the appellation's 2025 specification, the cahier des charges (its official rulebook), and a 2007 order on age accounting.

Armagnac production at a glance

What Armagnac is made from: grapes and vineyard rules

Armagnac is made from wine, and the wine comes from ten authorized grape varieties, led today by Ugni Blanc, Folle Blanche, Baco, and Colombard. Baco is a hybrid bred after phylloxera, and the BNIA, Armagnac's trade body, describes it as particularly suited to the sandy soils of Bas-Armagnac. The full list is in our guide to what Armagnac is.

The rulebook reaches into the vineyard itself. Vines must be planted at least 2,200 per hectare (about 890 per acre), with rows no more than 3.5 meters (about 11.5 feet) apart, and pruned every year. Yield is capped at 120 hectoliters of wine per hectare. The specification's reasoning is practical: higher yields favor the light, acidic wine distillers want, but past a point they cost aromatic ripeness.

Only identified parcels qualify, and the grapes must be harvested, vinified, and distilled within the appellation's listed communes. Our guide to the Armagnac regions explains how those communes divide into Bas-Armagnac, Ténarèze, and Haut-Armagnac.

Harvest and wine-making: a wine built for the still

A table-wine grower may wait for full ripeness. An Armagnac grower picks early. The BNIA says the grapes are deliberately harvested before full maturity to keep acidity up and alcohol low. A 2020 French Ministry of Culture heritage inventory places the harvest in September and October, about two weeks earlier than it used to be because of climate change.

The wine rules are short and strict. Enrichment (adding sugar to raise alcohol) and sulfiting are banned for the grapes, the must, and the wine. Until distillation, each tank must show 7.5% to 12% natural alcohol and no more than 20 milligrams per liter of total sulfur dioxide, a ceiling that allows for the trace that occurs naturally.

The specification gives the reasons. Acidity keeps the wine sound through the winter, and low alcohol concentrates its aromas in the spirit. The sulfite ban limits acetaldehyde in the eau-de-vie (French for distilled spirit, literally "water of life").

The wine goes to the still without its coarse lees, the heavy sediment, but it keeps its fine lees, the light yeast left in suspension. According to the Ministry of Culture inventory, producers credit those fine lees with the spirit's roundness.

How the Armagnac still works

Most Armagnac comes from the alambic armagnacais, a copper column still that runs continuously. According to the specification's 2012 figures, 95% of that year's 185,000 hectoliters of distillation wine went through this type of still. Inside it, wine and vapor travel in opposite directions:

1. Cold wine flows into the bottom of a tank that surrounds the condensing coil, and it cools the alcohol vapor inside that coil.
2. Cooling the coil warms the wine, so it reaches the column preheated. This part of the still is the wine heater, or chauffe-vin.
3. The warm wine trickles down the column from plate to plate toward a boiler heated by direct flame.
4. Vapor from the boiling wine rises the other way, bubbling through the wine on each plate and picking up alcohol and aroma as it climbs.
5. The vapor condenses in the coil into clear spirit, while the spent wine drains out through an overflow.

The rules keep the still small. The boiler, column, plates, and coil must all be copper. The column may hold no more than 15 plates, only two of which can be concentration plates. No still may produce more than 40 hectoliters of pure alcohol a day.

Armagnac distillation: strength, deadline, and repasse

Armagnac comes off the still at a relatively low strength. The legal range is 52% to 72.4% ABV, and the BNIA puts the traditional range at about 52% to 60%. The specification links that low strength to a high level of aromatic compounds, and the BNIA says the still doesn't purify the spirit excessively. The Ministry of Culture inventory reports 15 to 20 liters of Armagnac from 100 liters of wine, a ratio we come back to in why Armagnac is rare.

Distillation must be finished by March 31 of the year after the harvest. The BNIA notes that for several years an annual decree has set an earlier date.

The specification also allows repasse, batch double distillation in a pot still of the kind used for Cognac. The first heating yields a low-strength brouillis. The selected heart of the second run, the bonnes chauffes, must measure 65% to 72.4% ABV. Any distillery using repasse must also run at least one Armagnacais still that season. The BNIA says double distillation has been authorized since 1972 and is often used for spirit sold young. For where the column still came from, see Armagnac history.

Traveling stills and estate stills

Traveling distillers are an Armagnac tradition. The specification, using 2012 data, says most grower-producers relied on them, with stills moving from property to property through autumn and winter. The BNIA also describes wine distilled on the estate and at professional distilleries and cooperatives. Our guide to who makes Armagnac counts the stills and explains who owns them.

Armagnac aging: oak casks and the cellar

The new eau-de-vie is clear, and the BNIA describes it as fiery but already fruity and often floral. It goes into casks of sessile oak, pedunculate oak, or a cross of the two. The BNIA describes the standard cask, the pièce, as a 400-liter barrel (about 106 US gallons), mostly from Gascon or Limousin forests. The Ministry of Culture inventory says coopers mainly make 420-liter pièces (about 111 gallons).

The BNIA says the spirit stays in new barrels only until the wood has given what it should, then moves to older casks to avoid excess wood. Aging happens in a chai, the aging cellar, which the specification requires to be closed, sound, and ventilated in a way that can be adjusted to the weather outside.

Inside the cask, the specification says, water, alcohol, and other volatile compounds evaporate at different rates, wood compounds dissolve into the spirit, and it slowly oxidizes. Cask size and age, plus the cellar's temperature, humidity, and ventilation, steer those changes. Scotch drinkers know the evaporation as the angels' share, and the BNIA says it lowers strength by about half a degree a year.

When the cellar master judges very old spirit to be at its peak, sometimes after as long as 50 years, the BNIA says it moves into glass demijohns called bonbonnes. The glass stops any further extraction from the wood.

How Armagnac's age is counted

Armagnac tracks age through official age accounts, or comptes d'âge, set by a 2007 order that counts age for spirit held in wood:

• Compte 00 runs from the day of distillation until the following March 31.
• On April 1 after the harvest year, spirit in wood moves to compte 0.
• On each later April 1, spirit in wood moves up one account, so compte 1 means more than one year of aging.
• A blend of different accounts takes the account of its youngest spirit.

Take one harvest. Grapes picked in autumn 2024 and distilled that winter enter compte 0 on April 1, 2025, and they reach the one-year minimum on April 1, 2026.

Label terms such as VSOP and XO build on these accounts and always describe the youngest spirit in the bottle; a vintage names one harvest and may not be blended with other years. The minimums for each term are in our guide to what Armagnac is.

Reduction and finishing

The spirit leaves the still at 52% ABV or more and must be at least 40% when sold. Evaporation closes part of that gap, and water can close the rest. The specification says the cellar master adds water when needed, gradually through aging and finishing. The BNIA describes the traditional tool, petites eaux: distilled water blended with Armagnac, aged separately and used only for reducing.

Not every cask gets water. The BNIA says vintages often go unreduced, especially from humid cellars, and are sold at their natural strength, generally 40% to 48%. Bourbon fans will recognize the idea from barrel-proof bottlings. In Armagnac, neither the specification nor the 2007 order defines "cask strength" or "single cask," so on a label those words are the bottler's own description.

Beyond water, the specification permits only caramel for color, sweetening with defined products, and an infusion of oak chips in hot water, all within a combined limit. A permitted addition isn't a required one, so the useful question is what was done to the bottle in front of you.

Blend, vintage, or single cask

The specification says Armagnacs on the market are often blends of different ages or grape varieties, and some carry a vintage, with the cellar master choosing by tasting. A vintage keeps to one harvest year but can still combine several casks from it. A single cask, what a bourbon label would call single barrel, is one barrel bottled on its own, so each release carries one cask's history.

Bottling: where aging stops

Armagnac is bottled as needed, and from then on it no longer ages. When a label shows both a vintage and a bottling date, the gap between them roughly measures the spirit's time in cask, unless some of those years were spent in glass.

What reaches our bottles

Reduction and finishing are the last chance to adjust an Armagnac before it's bottled. We choose every cask directly from the source, and each OADE bottling is that one barrel at cask strength with no additives, just as it is tasted in the cellar. You can browse our current single-cask releases.
