Visible residue, like fingerprints or lipstick, is not the only form dirt and grime can take on glassware. Fat or grease-based residues like milk or dish soap can all leave a clear film on glass. This film causes the speedy release of carbonation, causing your beer to go flat, and changing the taste. Odors absorbed from stale air, smoke, or drying towels, may also give beer an off-taste. Find out if your glass is really beer clean by looking for carbonation bubbles on the inside of the glass. On a beer clean glass there will be no irregularities or impurities for bubbles to form on. If you see bubbles clinging to the sides of a glass, it’s a sure fire sign that the glass has some residual impurities from soap, food, or something else.
You can also beer clean “test” your glassware. The three most common techniques are the sheeting test, the salt test, and the lacing test. The sheeting test involves dipping a glass in water. If the glass is clean, the water will evenly coat it. If there is an invisible film, the water will break up into droplets on the inside surface. For the salt test, sprinkle salt on the inside of a wet glass – it will not adhere to the parts that still contain a greasy film. The lacing test happens after a glass has been filled with beer (so we recommend not wasting your finest pours with this particular test). As a beer is consumed, the foam should adhere to the inside of the glass in uniform, parallel rings forming a lace pattern. If there is film, there may be a random pattern from the foam or no pattern at all.
An easy way to keep your glasses beer clean without any special processes is to make sure that your beer glassware is used for just that- no milk, soda, or juice.
Beer clean glasses are cleaned in a very specific way with certain techniques and special cleansers. According to the DBQM, there are two acceptable, effective ways to clean your glassware for guaranteed beer clean results: manually washing in a three-tub sink or using a dedicated automatic glass washer from https://www.shopupster.co.uk. For manual cleaning, it is important to clean sinks and work area prior to cleaning the glassware. First, clean the glass in hot water with a detergent that is not fat or oil-based. Make sure not to empty any water from the glass into the cleaning water so cleaning solutions are not diluted.
Second, scrub the entire glass (interior, exterior surfaces, and the bottom of glass) with a cleaning brush to remove film and residue. Using motorized cleaning brushes will allow for a more thorough washing. Then, make sure to rinse in cold water. Finally, sanitize the glass in the third sink filled with hot water and an appropriate sanitizer. If using a glass washing machine, it’s imperative that you dedicate this machine to bar and beer glassware only. Wash glasses with equipment from https://www.shopupster.co.uk at a hot temperature (between 130º and 140º) and use the correct detergent, sanitizing, and/or rinsing agents.
Check concentrations daily and regularly service the machine to keep its performance where. Storing your beer glassware after you’ve got it clean is nearly as important as the cleaning itself. Air drying is best as drying towels can leave behind odors or lint. If you do use towels, make sure to use lint-free towels and let them thoroughly dry between uses to prevent mildew growth. Store your beer clean glassware in a stainless-steel wire basket for maximum air circulation. Glassware should be stored in an area free of odors, smoke, grease, or dust. If storing glasses for frosting, make sure the freezer is clean and odor-free.Learn More
