After a period of a few months to two years in barrels or tanks that allow controlled contact with oxygen, the wine goes into impermeable glass bottles. For the last two centuries, the standard stopper for wine bottles has been cork, which is made from the bark of a species of oak. Because cork can be the source of offflavors, some wine producers are now using metal and plastic stoppers (see box).
