Define when a bottle’s drinking window opens, peaks, and closes, and the tool shows whether today falls inside it — with a position marker on the window itself.

FAQ
Common questions
The answers collectors
most often ask.
It is still yours to enjoy. Old bottles past their window carry historical and emotional value even as the fruit fades — drink it for the story it tells.
Start from the producer’s guidance, professional reviews, and regional tradition. For most collectors, a conservative window is the safer bet.
Because "now" is what matters. The reference year is today, so the verdict always reflects the present state of your bottle — no math required from you.
