Moulds are usually black or brown in colour but can sometimes be red, they can get into the system when changing kegs & casks or even when beer is being dispensed.īacteria – Not the sort of bacteria found in your kitchen which can cause food poisoning or in cases of extreme contamination death. Mould – Comes from the air in your cellar and are all around us, they like to live in damp conditions exposed to the air, so will grow on cellar walls, couplers, cleaning sockets, the tops of kegs and casks, spouts and drains. Usually they look white or grey in colour and can have a sandy or stringy appearance. If wild yeasts are on the couplers then there is a chance they can get into the system during cask/keg changes and cause an infection. They are usually found on the outside parts of the beer line system such as the couplers, spouts, sparklers and drains. Yeasts – These can either occur from brewery yeasts left over from the brewing process or even wild yeast which are found floating around in the air of the cellar (Some beers such as Lambic styles use wild yeasts in the fermenting stage to give a sour taste). Because of modern purification and filtration systems beerstone is less of an issue than it traditionally was and mainly effects Cask beer lines as these are unfiltered live products. Beerstone is formed from a chemical reaction of Oxalic Acid (produced during the brewing process) and calcium from water hardness. Limescale – This comes from the fresh water you use to rinse lines and will mostly affect Cask Beers (because keg lines are not usually flushed after each keg is emptied), you will also see it on taps and in your kettle as a white solid layer.īeerstone – This is a generic term for Calcium Oxalate and looks a little like limescale but is a beige/brown colour. More information on what makes beer turn bad can be found in the article ‘That ‘Taint Right’ What are the main contaminants that can build up in my lines? If contaminants are allowed to establish themselves then they will ruin your beer. Beer is a food and while no one has been seriously harmed from drinking bad beer they can be made very ill which will impact your public image, reputation and ultimately your sales.Įach type of beer has it’s own colour, clarity, aroma and taste. Why should it matter if they get dirty?īecause someone’s going to drink it! Dirty beerlines can taint beer.

This is because over time deposits of limescale, beerstone, yeast, hops and proteins that have not been filtered out properly as well as bacteria can build up on the walls of the dispense lines. Everyone who owns and runs a pub, bar or restaurant with a draft dispense system should regularly clean their beerline system.
