Does Languedoc wine age well?

When we bought our house 2 years ago, we inherited a collection of about 100 dusty bottles in various shapes and sizes. Most are label-less and contain a liquid of an indeterminate mid brown colour, together with a fair quantity of muddy deposit. There are a few labels remaining which provide clues as to the contents.`1954 Maccabeu``1964 Carthagene`Èau de Vie`.

Over the last few days I've been opening a few bottles each day in an effort to free up some space. And, yes, not surprisingly the wines are pretty disgusting and completely past it. With a burnt, madeira like smell too which comes from the estufa conditions in our attic - 40°C in summer and 2°C in winter.

But it got me thinking about how well Languedoc wines age. Obviously not the ones in my attic but in the 1950s there were hardly any serious wines coming out of the Languedoc. It wasn't until the late 70s, early 80s that more producers, old and newly established, started bottling wines that had the stuffing to age. I've tasted some excellent 1998s recently which still taste youthful and have at least 5 years more life in them. And the 1982 Mas de Daumas Gassac is, by all accounts, still very sprightly. I'd be interested to hear of any good, old bottles that readers have come across.
