A wine is legible long before it's tasted. The bottle reports on its storage; the glass reports on its age. Learning to read both is the skill that separates the collector who opens bottles at their peak from the one who guesses — and it's the same literacy that protects you at auction and at the table.
On the bottle: how it lived
Fill level (ullage) is the headline. As a cork slowly breathes, the level drops; an unusually low fill for the wine's age signals a hard life or a tired cork. Check the capsule and cork for seepage — sticky residue down the neck means wine pushed past the cork, usually from heat. A pristine label is cosmetic, but a stained or bulging one can hint at temperature abuse. None of these are death sentences in isolation; together they sketch a storage history.
In the glass: color and rim
Tilt the glass against white light and look at the rim. Young reds are vivid purple-ruby to the edge; with age the rim lightens toward garnet, then brick, then amber — the most reliable visual age gauge there is. Whites travel the opposite road, deepening from pale lemon toward gold and amber. A red gone brown at the core or a white gone deep amber before its time is telling you the window is closing — or closed.
On the nose: primary to tertiary
Aromas march from primary (fresh fruit, floral) through secondary (oak, yeast) to tertiary (leather, forest floor, dried fruit, mushroom, petrol in Riesling). A wine showing generous tertiary character is mature; one still locked in primary fruit has time to give. Reading this arc tells you whether to decant for air or merely for sediment (see our decanting guide) — and, more importantly, whether tonight is the night or whether this bottle wants another five years.
