One of the biggest changes in wine storage and enjoyment was the invention of glass in the days of the Roman Empire. Glass is non-reactive and can store wine for decades without altering its flavor. Suddenly wine bottles and glasses were used everywhere to preserve and drink wine. Cork was found to be the best material to stuff in the bottle's opening, to keep out the air but be easily removable later on when it was time to drink the wine.
Here are several photos of an old hand-made wine bottle I own. The green glass helps to prevent the wine from spoiling due to sunlight exposure. There is a 'punt' or indention in the bottom of the bottle.
