In 1953, New Zealander Morton W Coutts developed the technique of continuous fermentation. Morton patented his process which revolutionised the industry through reducing a typical four-month long brewing process to less than 24 hours. His process is still used by many of the world's major breweries today, including Guinness.

Today, the brewing industry is a huge global business, consisting mostly of conglomerates formed out of a multitude of smaller producers. While beer is generally an alcoholic beverage, some varieties exist, originating in the Western world, which undergo a process to remove most of the alcohol, producing what is called non-alcoholic beer.
