Input: Beer
Most beers are cleared of yeast by filtering when packaged in bottles and cans. However, bottle conditioned beers retain some yeasteither by being unfiltered, or by being filtered and then reseeded with fresh yeast. It is usually recommended that the beer be poured slowly, leaving any yeast sediment at the bottom of the bottle. However, some drinkers prefer to pour in the yeast; this practice is customary with wheat beers. Typically, when serving a hefeweizen wheat beer, 90% of the contents are poured, and the remainder is swirled to suspend the sediment before pouring it into the glass. Alternatively, the bottle may be inverted prior to opening. Glass bottles are always used for bottle conditioned beers.

Article: Combined with this influx of classical ideas was the invention of printing which facilitated dissemination of the printed word and democratized learning. These two things would later lead to the Protestant Reformation. Toward the end of the period, an era of discovery began (Age of Discovery). The rise of the Ottoman Empire, culminating in the Fall of Constantinople in 1453, eroded the last remnants of the Byzantine Empire and cut off trading possibilities with the east. Europeans were forced to seek new trading routes, leading to the expedition of Columbus to the Americas in 1492, and Vasco da Gama's circumnavigation of India and Africa in 1498. Their discoveries strengthened the economy and power of European nations.
