Looking to add the Sidecar, the Vieux Carre, and a few others to my rotation, and so it's time to make a cognac purchase. I don't quite know how. Any recommendations in the $30-40 range? Poking around the internet I've found that those who review this stuff can't imagine mixing it with anything, except for coke, which is unfortunate, as I'm interested know what works well in actual cocktails. Not much of a sipper.
