75cl is 750ml.

cl is the abbreviation of centiliter, which is a unit of capacity that is commonly used in the brewing industry. The conversion relationship with ml (millilitre) is 1cl (centiliter) = 10ml (millilitre) = 0.01 L (litre). So 75cl=75*10=750ml.

Cl is a commonly used term in the brewing industry and bartenders, and ml is a widely used unit of liquid volume measurement in the world. Nowadays, most alcoholic products on the market are marked with ml (millilitre), while cl (centiliter) is rarely used. However, in Western countries, winemaking circles are still accustomed to using cl (centiliter) instead of ml (millilitre).

On the market, we see wine bottles with different shapes and heights, but they all have the same volume - 750ml. The capacity of the original imported red wine is marked as 75cl instead of 750ml. The capacity calculation unit of cl is also one of the signs of identifying imported red wine.

Historically, the volume of standard wine bottles was not uniform. It was not until the 1970s that the European Union set the size of standard wine bottles at 75cl in order to promote standardization. However, there are still some countries where the standard bottle is 50cl. For example, Hungary's Tokay sweet wine uses 50cl bottles to hold wine. In addition to standard bottles, there are also sprinkler bottles that are smaller or larger than standard bottles.

Summary

No matter whether the wine label uses cl or ml, the bottom of the imported wine bottle must be marked with the "cl" measurement unit. This is inseparable from the local traditional bottle-making techniques and habits, and the bottles of each region and each winery have their own characteristics.
