How to Read a Grape
Every noble variety has four dimensions:
- Structural signature — body, tannin, acid, alcohol tendency. Genetic and climate-independent.
- Aromatic range — what it smells like in cool vs. warm climates, young vs. aged.
- Winemaking sensitivity — how much it changes with oak, lees, oxidation, or extraction.
- Terroir expression — the regions that push it toward its best self.

Three Key Distinctions
Aromatic vs. neutral grapes. Riesling, Gewürztraminer, Sauvignon Blanc announce themselves. Chardonnay whispers — its flavor comes from terroir and winemaking. When assessing an unknown white: aromatic = follow the scent; neutral = read texture and weight.
Tannin sources in reds. Nebbiolo and Cabernet are both high-tannin but different in origin — Nebbiolo from cool-extracted skin contact, Cabernet from thick skins in warm ripe fruit. Same scale number, different mouthfeel.
Acid as the aging engine. Riesling ages because of acid. Pinot ages because of acid plus light-tannin secondary complexity. Grenache doesn't age well solo — neither acid nor tannin in sufficient quantity.
