It’s no surprice to the champagne lovers that large formats mature slowly & offers a grand experience. The main change in sizes and shapes for wine bottles began taking place in the early to mid 1700’s.
The different wine bottle shapes and sizes started taking shape once it was discovered that cork could act as a sealing agent, which allowed the wines to age or at least not spoil.
The next step in the evolution of wine bottle shapes and sizes came about when it was discovered that larger bottles not only looked better, they could also change the taste of a wine. This ability to change took place because the larger sized wine bottles allowed the wine to age and develop over longer periods of time than the standard glass bottles of the day.
