I read a few wine blogs -- but none of them beat this board for best, fastest, soundest advice, in my opinion. You wine aficionados here are terrific. Thank you for all your past advice, and now: what wine book (the ONE best) would you recommend to someone who wants to have a ready reference for varietal characteristics, tasting tips, and general wine knowledge? I picked up a Hugh Johnson at a yard sale, but it's dated and limited. Help!
