How to Tell if Wine Is Corked

Updated August 2026

Corked is TCA taint talk — not a -month clock and not “the cork crumbled.” 2,4,6-trichloroanisole is a fault word, not a TTB type. A crumbled cork can still pour a clean wine; a sound cork can still be corked. -day Typical US table ~12% Black Box is bag-in-box — no cork. Sparkling closures are a different package. A 5-ounce 12% pour is one NIAAA drink.
