When should you open it?

Search for a wine by producer or vintage. The calculator looks up the wine in our database, where every bottle has a drinking window calculated by the Cellared Ageability Index, our 10-factor model. Click any result to see the full drinking window, current phase, tasting notes, and cellaring guidance.

Yes. No signup, no credit card, no rate limits. The calculator uses the same drinking window data that powers the Cellared app. We make money on subscriptions inside the app, not by gating this tool.

Cellared publishes a curated set of cellar-worthy wines each week. The catalog grows steadily. If your wine is not yet in the public guide, you can still track it inside the Cellared app, where the same model runs against the full database.

The Cellared Ageability Index is built on professional vintage reports, producer house style data, and varietal aging curves. The window is a range with a shape (open, peak start, peak end, close), not a single number. We cannot account for your specific storage conditions or individual bottle variation. See the methodology page for the full breakdown.

Yes. Inside the Cellared iOS app, every bottle you log gets a drinking window automatically. Import your cellar from a CSV or CellarTracker export, and the windows are ready in three minutes. Free to start, unlimited bottles.
