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.
