Most wines are sold in glass bottles and are sealed using corks. Recently, a growing number of wine producers have been using alternative closures such as screwcaps or synthetic plastic "corks". Some wines are packaged in heavy plastic bags within cardboard boxes, like breakfast cereal, and are called box wines or cask wine. One advantage of box wine is that it can stay fresh for up to a month after opening, while bottled wine will start to oxidize immediately. The wine in a box wine is typically accessed via a tap on the side of the box. In addition to being less expensive, alternative closures prevent cork taint, although they have been blamed for other problems such as excessive reduction.
