I just wish to add that with Cognac it's far more difficult to find good stuff than with whisky. Not only do many of the producers tart up their brandy with colouring but they add sugar syrup to sweeten the taste so most people won't be offended by their product, hence my earlier argument that despite colouring and chill-filtering whisky looks like the slightly more honest product.
However, there are good producers making good uncoloured non-additive products like the terrific producer Leopold Gourmel. This stuff is so much better than the ordinary "Remy Martin" luxus brands. There is a danger however to "put off" people who expect the ordinary sweet stuff........
Christian, I am very curious to try some good cognac. Can you tell me, off the top of your head, which common brands are tarted up, and which are not?
