A beer bottle is a bottle made to contain beer, usually made of
glass and come in various sizes, shapes and colours. Dark amber
or brown glass greatly reduces UV light from spoiling the beer.
However, lighter colored bottles are often used for marketing
reasons. Bottling lines  Bottling lines are production lines
that fill beer into bottles on a large scale. This typically
involves drawing beer from a holding tank and filling it into
bottles in a filling machine (filler), which are then capped,
labeled and packed into cases or cartons. Many smaller breweries
send their bulk beer to large facilities for contract
bottling—though some will bottle by hand. The first step in
bottling beer is depalletising, where the empty bottles are
removed from the original pallet packaging delivered from the
manufacturer, so that individual bottles may be handled. The
bottles may then be rinsed with filtered water or air, and may
have carbon dioxide injected into them in attempt to reduce the
level of oxygen within the bottle.
