This corresponds to a standard capacity of a bottle of wine.
The choice of the 750ml capacity for wine bottles has a long and interesting history. This tradition dates back to the 18th century in France, when rules and conventions were established regarding the packaging of wine in bottles.
There are several reasons why this capability has become the standard:
Adequate capacity: A 750ml bottle is sufficient to serve several portions of wine (generally 4-6 glasses) without the wine risking rapid deterioration once opened.
Tradition: The 750ml capacity has become a traditional format, one that producers and consumers have become accustomed to over time.
Standardization: The 750 ml format has allowed greater standardization of the production, packaging and distribution of wine, simplifying trade both nationally and internationally.
Distribution: The 750ml bottles are quite handy and stack easily in crates during transport and storage.
Regulations and laws: Over the years, many regulations and laws in the wine sector have been adapted to the 750ml format.
However, it's important to note that there are other wine bottle formats as well, each with specific names. For example, 375ml bottles are called "half bottles" and 1.5 liter bottles are called "magnums". There are also larger and smaller formats, but the 750ml format remains the most common and popular.
