Selective waste collection began in Rome, as evidenced by Mount Testaccio, an artificial hill 50 metres high with a base of 22,000 square metres built from the remains of 25 million amphorae in which olive oil was transported from Hispania to the city.

The production of amphorae was simple, the handles helped in their handling and they were easy to transport on ships - the holds were covered with sand and the lower conical part was partially buried in it. So, in Greece and Rome they became the standard containers for transporting the most precious liquids: wine and olive oil. So why and when did the Romans abandon clay amphorae in favour of oak barrels?
If amphorae were the appropriate container for naval transport, for land transport, their shape did not make them easy to transport in wagons. It was in the middle of the 1st century BC when the Roman Republic subdued Gaul, and the invaders learned how the Gauls stored and transported beer... in oak barrels. The Roman legions were the first to adopt oak barrels to transport the wine that accompanied them on their many conquering expeditions, abandoning the cumbersome amphorae.

Although nowadays the use of French or American oak for wine ageing is the norm due to the characteristics and particularities of the wood, at that time the choice of oak was not related to winemaking methods and crianza but to the abundance of these trees in Europe and because their wood can be bent relatively easily to make barrels.
Following the example of the army, the merchants of Rome quickly adopted wooden barrels instead of amphorae: they were stronger than clay, weighed less and could be moved with less effort by rolling them. Moreover, unlike clay, wooden barrels allow oxidation and add flavours, smells and nuances. In this way, they found that wines shipped over long distances in oak barrels improved when they arrived at their destination.
So, if oak barrels began to be used for the ease of transport and the quantity of wood, today they have to do with the smell and taste they bring to the wine.
Not to mention that due to the high risk of shipwreck, the barrels float and a large part of the wrecked ship's cargo could be recovered.
