Bottling lines are production lines that fill a product, generally a beverage, into bottles on a large scale.

Packaging of bottled beer typically involves drawing the product 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. Virtually all beer bottles are glass.
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. The bottle then enters a "filler" which fills the bottle with beer and may also inject a small amount of inert gas (usually carbon dioxide or nitrogen) on top of the beer to disperse the oxygen, as oxygen can ruin the quality of the product via oxidation. Finally, the bottles go through a "capper", which applies a bottle cap, sealing the bottle. A few beers are bottled with a cork and cage.
Next the bottle enters a labelling machine ("labeller") where a label is applied. To ensure traceability of the product, a lot number, generally the date and time of bottling, may also be printed on the bottle. The product is then packed into boxes and warehoused, ready for sale.[1]
The process for bottling wine is largely similar to that for bottling beer, except wine bottles differ in volumes and shapes. Traditionally, a cork is used to provide closure to wine bottles. After filling, a bottle travels to a corking machine (corker) where a cork is compressed and pushed into the neck of the bottle. Whilst this is happening, the corker vacuums the air out of the bottle to form a negative pressure headspace. This removes any oxygen from the headspace, which is useful as latent oxygen can ruin the quality of the product via oxidation. A negative pressure headspace will also counteract pressure caused by the thermal expansion of the wine, preventing the cork from being forced from the bottle. Champagnes and sparkling wines may further be sealed with a muselet, which ensures the cork will not explode off in transit. Many alternative wine closures are emerging in the market, such as screw caps.
Some bottling lines incorporate a fill height detector which reject under or over-filled bottles, and also a metal detector.
After filling and corking, a plastic or tin capsule is applied to the neck of the bottle in a capsular. Next the bottle enters a labeller where a wine label is applied. The product is then packed into boxes and warehoused, ready for sale.
