Calibrate your perception

A self-teacher needs calibration. That means checking whether the thing you think you taste matches a stable reference. Without calibration, every wine becomes "smooth," "bold," or "nice," and those words do not teach much. Start with sweetness. Taste a clearly dry white beside an off-dry Riesling or Moscato d'Asti. Notice that fruitiness is not the same as sugar. A dry wine can smell fruity and still finish dry. Sweetness leaves a sense of sugar on the finish. Calibrate acid with contrast. Taste a crisp Sauvignon Blanc or Riesling beside a rounder, lower-acid white. Acid makes your mouth water and gives the wine a line. If the wine feels flat after acidic food, the dish may have more acid than the wine. Calibrate tannin with red wine. Compare Pinot Noir or Gamay against Cabernet Sauvignon or Nebbiolo. Tannin dries. It is grip, not bitterness alone. Ask where you feel it: gums, tongue, cheeks, or the whole mouth. Calibrate body by weight. A light white, a richer Chardonnay, a light red, and a full red will teach more than a definition. Body is how much space the wine takes up. Calibrate oak carefully. Oak can show as toast, vanilla, spice, smoke, cedar, or just roundness. Do not call every rich wine oaky. Some richness comes from ripeness, lees, lower acid, or texture. Use references, not guesses. From lesson three you'll remember the regional anchors. Put those anchors to work by tasting known examples and asking whether the standard description actually shows up in your glass. Agreement is useful. Disagreement is useful too, if you can explain it.
