I'm just wondering what your favourite and least favourite cognacs are, and what you would be willing to pay for a glass of exceptionally good cognac such as Remy Martin Louis XIII.
My favourite is probably Remy XO. I missed the opportunity to try Extra at the reasonable price of £8 a glass (the bottle ran out and there's no chance they'll replace it with such crap profit margins) and I'm worried I do the same for Louis XIII which, while £42 a glass sounds awful, I doubt you could find cheaper.
