Umami
I totally did not understand this, despite being completely into wine (and cooking). That is, until I read Jamie Goode's book The Science of Wine. I completely trust JG, and he describes it as the meaty or savory component of taste. That I can understand. So now, I go with it. Oh, and Heston Blumenthal also is someone who recognizes umami. So, I guess you can put me in the believer area now. cheers, Bonnie
