Good whisky, like the English language correctly used, is memorable. Sitting at a long table last night with a dozen other whisky aficionados in the basement of the Vinissimo wine boutique near Kropotkinskaya, I was told by the tastemaster, Yuri, from the site http://www.whiskyon.ru/, that a good whisky is one which, after you have brushed your teeth at night and got into bed, you can still taste as you fall asleep. I felt like saying: I know the feeling.
I have read what whisky writers say about the types of taste they experience. I find it impossible to express taste in words. What I do find is that different tastes provoke different associations in the mind. I am sure that this is different for every drinker, and differs in the same drinker from day to day. Which is part of the endless fascination of malt whisky. Appreciating it is a more a question of psychology than liquid gastronomy, if I might put it like that.
