What is armagnac?

Cognac comes from Cognac.

Armagnac comes from the South West of France.

Main difference is double distillation in Cognac, single in Armagnac.

Cognac is from almost 100% Ugni Blanc (trebbiano).

both are brandies, from different regions.

No. Cognac is one brandy-producing AOC; Armagnac is another. Both produce aged grape brandies from similar varietals. All cognac is produced using pot stills and double-distillation; some armagnac is made the same way, but much of it undergoes a single distillation in a column still. Both areas produce excellent brandies, mediocre brandies, and undrinkable brandies.

For simple questions of fact like this, a Google (or other search engine of your choice) search is often preferable to a Usenet post. A more substantive or subjective query (such as "What's a good value armagnac under $80?") provides better fodder for group discussion.

In general, due to single distillation, Armagnac is generally more "fiery" in its flavor. Many Armagnacs carry a single year vintage, unlike Cognacs. Yes I know that one can find single vintage cognacs, but to a lesser extent than with Armagnac.

If you can find an Armagnac made from folle blanche, snap it up. It has a wonderful violet appearance.
