OXYGEN IN THE BOTTLE NECK

Oxidation or other exposure to air beer is one of the defects met at beer to be stored for a relatively long time. Beer various types break down at different speeds and emit unpleasant odors. Oxidation causes changes in taste, flavor and color also. It should be noted that the most critical points in the production process is packaging beer because beer goes in a container full of air. The less oxygen is absorbed especially during the process of filling and maintaining more stable beer would be the smell. Reducing contact with oxygen during the transfer and packaging of beer leads to reduction of oxidation but actually oxidation is inevitable. In the early stages of oxidation beer gets a bad smell and a further oxidation as it has flavor of honey and finally flavor as wine and dried fruit as mature too many.
