Brewers frequently struggle with the best way to ensure microbial free equipment. All trademarks are the property of Birko except where otherwise indicated. However, a problem can occur with iodophor if the amount used is not accurately measured. A traditional procedure for cleaning and sanitizing utilizes the following steps: 1. Sodium chlorite is also a toxin and an irritant. In his book, The Complete Joy of Homebrewing, Charlie Papazian recommends using 2 ounces of bleach per 5 gallons of water to clean and sanitize fermenters and bottles. For bleach with a higher concentration, contact your chemical supplier. Rinse with cold water. Once a system for cleaning and sanitizing is established that actually works and a quality beer is produced, it is tough for change to occur. If the sanitizing solution begins as a sodium chlorite solution, 8.3% by weight, and the known reaction efficiency is 97%, then the yield will be 6% chlorine dioxide. Chlorine dioxide (ClO2), like iodophor, is very effective at destroying spore forming organisms at low active parts per million (ppm) levels and does not flavor beer when used properly. The recommended concentration for disinfection has been 600-800 ppm of chlorine bleach and 50 to 200 parts per million (ppm) for sanitizing. Protecting the food chain for over three generations. Since ClO2 test kits are designed to check low (. Learn more about our peracetic acid sanitzer: Birk-Ox ➔. Inhalation of chlorine dioxide gas causes coughing, a sore throat, severe headaches, lung oedema and bronchio spasma.

For a 1.75% titratable iodine concentrate, no more than 1 (one) fluid ounce per 5 gallons of water should be used to achieve 25 ppm active. For vessels that will be refilled with beer within a few hours, chlorine dioxide works best to give a quick kill without flavoring the beer. Conversely, chlorine dioxide is ideal for sanitizing after the cleaner has been rinsed. The formula listed below is based on this concentration. By continuing you agree to the use of cookies.

Once the gas is gone, it is gone; and unless additional sodium chlorite is added to the solution there will be no oxygenation to kill the bacteria. While the majority of brewers do not over use iodophor, occasionally it is noticeable in finished beer. Chlorine dioxide relies on oxygen chemistry (oxidation) to kill organisms. Think of it like carbon dioxide, (CO2). Remember: Sodium Chlorite is not Sodium Hypochlorite! Therefore, post-rinse sanitizing equipment and bottles is not recommended with hypochlorite bleach. One sanitizer was an acidified solution of dilute sodium chlorite at pH 2.7; the other sanitizer was dilute chlorine dioxide (about 15 ppm) in tap water. These solutions are basic in pH (8.0-8.5 @ 1%) and the end user must normally “activate” the solutions to generate the chlorine dioxide gas. In other words, you will still get an effective kill at an active level of 50-100 ppm ClO2 while maintaining a minimal or non-existent flavor profile. A 50-100 ppm chlorine dioxide solution should have little or no odor and that is why flavoring is not a problem. Basically, however, it comes down to three questions: These are the questions that need to be answered by the brewer before jumping in with both feet.
