You want a single-vineyard, single-vintage Cognac from the
Cognac region of France. There are other good brandies in
the world, i.e. California brandy from Germain Robard, but
you probably want the reference point of a good Cognac.
Here is a link to one retailer.

If you have a wine retailer you trust, ask them.
