Armagnac Baron De Lustrac was unique among the 12 armagnac houses I visited in the fall of 2014. Most houses grow grapes or make wine or distill wine or age brandy, but Baron De Lustrac, or more accurately the company Millésimes et Tradition, they mostly bottle up single-vineyard, single-grape, single-vintage armagnacs that have been stored on the property where they were distilled.
Sometimes they do help with the on-site aging, performing tasks for the cask producers like aerating the brandy as is done in armagnac. The process seems weird but in armagnac small producers are often very, very small and may only make a barrel each year.
Baron de Lustrac has made a few vintages that are vintage blends from different vineyards, but this seems like the exception to their usual single-single-single scheme.
The property that I visited is really a bottling facility. Here they blend, filter, bring down to proof, and bottle by hand in a two-room garage. All the bottling is on-demand, so when someone calls in an order that's when they go to work.
On site, there aren't a mass of barrels rolled in from the farms where it's made (armagnac barrels don't move around much), but they're transferred to plastic containers to bring to here. Some are very small containers, as a customer may have requested a single special bottle from their birth year, etc.
Their reduction to bottle proof strategy is a lot faster than at other producers: On the day I visited they reduced a 48% ABV 30 liter barrel down to 40%, which requires 53 liters of water. The water is added in stages by half each time: 25 liters, then 12, 6, etc. over the course of one day. (Other producers we visited would reduce little by little over years, often with 'petite des eaux' – water that ages alongside the brandy.)
Here they also add caramel color before bottling but say it is only an amount that brings the bottle back to the color of the barreled armagnac before they added water to it.
We were able to try tiny sips of some very old armagnacs including a 1979 Baco, a 1973 Folle Blanche, a 1965 Folle Blanche, and a 1936 Folle Blanche that had been in barrel until 2009. Our host described as "the youngest old man I ever met."
