Har faktiskt ingen koll. Roederer hade basårgång 2015 vilket jag kunde kolla upp via en app. Hur gör man med Bollinger?
Om jag minns rätt, finns en kod på flaskhalsfolien?
Saxat från Wineberserkers:
How to decode the approximate disgorgement date from a bottle of Bollinger (any cuvee)
1. On each bottle there is a lot number that is normally found printed on the neck foil of the bottle
2. This code will have the following pattern: L###### where # represents a number
3. These numbers correlate to the following LYDDDBB (L412604) where:
• Y is the last digit in the year; 4 for 2004
• DDD is the day of the year; 126 for the 126th day of the year (early May)
• BB is the batch number for the day; 04 for the 4th batch of the day
• This bottle L412604 was disgorged between January and May of 2004
So why isn’t this the actual disgorgement date? Bollinger actually uses this code to trace the labeling date of the bottle, but it will get you within 3 months of the disgorgement date (meaning the bottles are labeled up to 3 months after disgorgement). To determine the base vintage of the Bollinger NV wines, you can normally take 4 years off of the disgorgement date to get the base vintage, but depending on when the cuvee changes you can sometimes be off by a year (email Bollinger your lot number to ensure correctness).
