Sometimes you can learn a lot about a wine from a back label. Let's take the Bisol Prosecco di Valdobbiadene Crede for instance. This single-vineyard gem is not only thirst-slaking, palate-cleansing, and party-starting, but the good folks at Bisol are kind enough to let you know the vintage of the bottle in your hand. Even better, you can tell when it was bottled by deciphering the lot number. No Rosetta stone necessary: L10082 means it was bottled on the 82nd day of 2010. With most Proseccos, and sparkling wines in general, there is no way to discern freshness based on what you see on the label. (And here is where I must say that we sell oceans of bubbles at Esquin; nothing that we love sits around for any extended period of time.)
This is a practice I would like to see more sparkling wine producers undertake, beyond their vintage-dated offerings. For non-vintage wines that do not go through a secondary fermentation in the bottle, why not stamp the date it was bottled on the back label? If it's good enough for Budweiser, it's good enough for all your quality sparkling wines that peak in their youth.
