The brewing of Bass beer has undergone some changes in recent years, with different versions of the beer being brewed by different companies. Currently, as far as our knowledge goes, there are three main breweries involved in brewing Bass: Samlesbury Brewery in Lancashire, Marston's Brewery in Burton-upon-Trent, and possibly Wolverhampton Brewery as well.
Samlesbury Brewery, located in Lancashire, is responsible for brewing the keg and bottled versions of Bass. This brewery has a long history and is known for its expertise in brewing a wide range of beers. They have been brewing Bass for some time now and are committed to maintaining the quality and consistency of the beer.
On the other hand, the cask version of Bass is brewed by Marston's Brewery, which is located in Burton-upon-Trent. Marston's is a well-known brewery with a strong reputation for producing traditional cask ales. They have the necessary expertise and equipment to brew the cask version of Bass to meet the high standards set by the brand.
There has been some talk in the industry about production possibly being moved or overspilled to Wolverhampton Brewery. However, the information regarding this is not entirely clear, and it is uncertain if Wolverhampton Brewery is currently involved in brewing Bass or if it was just a temporary arrangement.
It is important to note that Bass is owned by AB-InBev, a multinational brewing company headquartered in Leuven, Belgium. AB-InBev is one of the largest beer companies in the world and has a portfolio of well-known beer brands. They oversee the production and distribution of Bass, ensuring that the quality and consistency of the beer are maintained across all breweries involved.
The brewing of Bass beer involves multiple breweries. The keg and bottled versions are brewed at Samlesbury Brewery in Lancashire, while the cask version is brewed by Marston's Brewery in Burton-upon-Trent. The involvement of Wolverhampton Brewery, if any, is uncertain. AB-InBev, based in Belgium, owns the Bass brand and oversees its production and distribution. These arrangements ensure that Bass continues to be brewed by experienced breweries with a commitment to quality.
