Why a wine bottle is 0.75l? Why? Why and where is it handed down?

The origin of the bottle, precisely made of glass, can be traced back to 1500 d. C., while the first evidence of the art of glass is a glass pearl dating back to 35 sec A.C. The most remote findings of one of the first ancestors of today’s bottle was an hollow glass vessels, even if it is impossible to determine their age precisely. They came from the pharaohs’ tombs and were small forms of “balsamari”, jars and goblets. These very delicate containers were for the exclusive use of the pharaoh during his journey into the “realm of shadows”. They were built with the technique “on friable core”: laborious and complex process that consisted of winding filaments of glass fused around a bag filled with wet sand or clay. The major production was due to the “balsamari” for, in fact, ointments and cosmetics.

These glass production system lasted until the first century A.C. until a very important fact occurred in Tire and Sidone: a true revolution in glass processing. A glassmaker had the brilliant idea of ​​using a tube made of glass and introducing its end into a crucible. The resulting molten glass was blown by the glassmaker: the glass bubble that was formed was then molded into a specific shape., This is how “blown glass” technique was born and it is still used today in the same way. This technique allowed the glass, previously used only for luxury items, to become raw material suitable for the production of consumer goods: bottles, jugs, flasks and vases of every shape and color for countless uses.

A glass amphora full of congealed wine from the 2nd century DC at the Speyer Museum in Germany. The wine, sweetened with honey, could not be evaporated thanks to the layer of oil placed on the neck of the bottle as an insulator. In contact with the air, in fact, the oil has hardened as much to become actual resin, avoiding the evaporation of the wine. Until the 5th century the major production of bottles,in fact, was destinated to oils, medicines, perfumes, and, above all, to wine.

Why bottles have precisely that type of shape?

Why do we use 75 cl bottles?

Concerning why wine bottles have this shape, there are various theories. According to one of them, it all depends on the pulmonary strength of the ancient glass blowers. When in 1700 the importance of conserving wine in glass began to be understood, it also started the production of containers suitable for this purpose, particularly bottles. The blowers, however, could not blow bottles larger than 65-75cl, so we opted for 75 cl bottles.

According to another theory, however, this particular unit of measurement is used because a bottle of this size contains exactly 6 125 ml glasses used in taverns. Hosts, this way, could easily calculate how many bottles would be served to their patrons.

Many people argue that this unit of magnitude comes from British, who measured volume in imperial gallons. Each case of wine could contain only 2 gallons. For this reason, they decided to enter 12 bottles in each box … 0.75 for each bottle.

Over time the production techniques have evolved and improved both in quality and speed of production and not least in possible variation of the bottle.

Over the years it has been studied how to improve and it is understood that the contact with oxygen makes the wine evolve and mature. Therefore the dimensions of the bottle are very important: a Magnum bottle has twice the capacity of the standard bottle and a smaller quantity of oxygen in contact with a greater quantity of wine. Result? A further step forward in the knowledge of wine and in the processing of glass and consequently in wine. In fact, the wine stored in Magnum reaches maturity more slowly, evolves in a more stable and protected, it resists better the temperature changes, but above all enhances its sensorial characteristics. The great wine lovers prefer them, because they expect to find greater freshness, great finesse and a greater complexity of aromas compared to the classic bottle.
