Causes of Beer Stone Formation

The formation of beer stone is promoted by various factors:

  1. Proteins and hop resins : During the brewing process, proteins and hop resins can precipitate from the beer and deposit on surfaces, especially those that regularly come into contact with beer.

  2. Minerals in water : Hard water, which contains high concentrations of calcium and magnesium salts, can promote the formation of beer stone, as these minerals can combine with other substances in the beer and form deposits.

  3. Temperature and pH : The temperature and pH of the beer can also contribute to the formation of beer stone, especially if the beer is not properly chilled or has insufficient pH.

Beer stone deposits can not only be unsightly, but can also lead to various problems:

  • Impairment of taste: Beer stone deposits can impair the taste of the beer and lead to undesirable aromas.
  • Clogging and malfunctions: In breweries and restaurants, beer stone deposits can lead to clogging of pipes, valves and other equipment, which can lead to malfunctions and production downtime.
  • Hygiene concerns: Beer stone deposits can be a breeding ground for bacteria and yeast, which can affect the hygiene and cleanliness of breweries and restaurants.

These cleaners often contain strong acids or bases that can effectively dissolve the deposits. Read the directions carefully and use protective gloves and goggles to protect yourself from the harsh chemicals.

  2. Mechanical removal : For stubborn deposits, it may be necessary to use mechanical means such as brushes, scrapers or high-pressure cleaners to loosen and remove the beer stone. Be careful not to damage surfaces.

  3. Preventive measures : To prevent the formation of beer scale, it is important to regularly clean and disinfect breweries, pubs and beer lines. Use filter systems to remove contaminants from the water and monitor the temperature and pH of the beer to ensure optimal conditions for storage and dispensing.
