Aalenien Wine

Actually, I'm guessing about the rocks, but it's the only explanation that makes sense. Aalenien is the highly rated signature wine of Domaine de Saumarez, a boutique winery near Montpellier that grows and vinifies mostly syrah and grenache grapes. The proprietors must have consulted a geologic map and been struck by the name. "Aalenien" is the French spelling of Aalenian.

The Aalenian Age ranges from 175.6 to 171.6 million years ago and is the first of four ages in the Middle Jurassic, which run in alphabetical order for your mnemonic convenience: Aalenian, Bajocian, Bathonian and Callovian. The age takes its name from the south German town of Aalen, where rocks of that age crop out (or were exposed by mining) in enough detail to establish this formal time division in 1864. Today the age is formally defined by the rocks, and the fossil ammonites in them, at a locality near Fuentelsaz in central Spain. There the Aalenian rocks are primarily limestone, and such is likely the case in Languedoc as well. Limestone characteristically offers good drainage and a ready calcium supply for vine health.

If I ever find this wine, I'll put up tasting notes.
