(TheGlobeandMail) - This doesn’t come easy, but I’ll say it anyway: For much of the population, professional wine recommendations are irrelevant. Yes, there will be ungracious attacks from online readers who sense they knew as much already, but at least now the wisecrack brigade can cite science in its defence. Many nuances in wine – say, the vanilla richness of an oak-aged chardonnay or the astringent grip of a Barolo packed with the bitter tannins found in grape skins – are simply lost on many tongues.
