Understanding What A Brewery Sanitizer Does

By Marcie Goodman


The brewing fraternity always subscribe to the notion that good brewing is seventy per cent cleaning. This implies that a beer batch is only as good as the cleaning agent. Therefore, after cleaning the brewing equipments the next important activity is sanitization. This is achieved by use of an agent called a brewery sanitizer. Most are chemical in nature and they do ensure that no foreign organism exists in the wort.

Sanitization is the most important preparation procedure in the beer making process. It needs to be highly valued as it has a great bearing on the success of the production batch. This is because it is the last step that can completely ensure that only the intended beer ingredients are in the fermentor. Wort is a magnet for a host of other microorganism that can compromise the beer flavor. Usually the main culprit is bacteria because it competes with yeast when in contact with the wort.

The mostly accessible decontaminator is Isopropyl.This chemical is an inorganic alcohol that is used in several sterilization procedures. It kills bacteria by paralyzing their basic body functions like energy production and cell detoxification. It is mixed with water in a two thirds proportion and in it the brewing items are soaked for a few minutes. One should exercise due care as alcohol can cause explosions even when mixed with water.

The next sanitizer is Iodophor, and it contains iodine that provides its sanitization properties. One teaspoon of iodophor is dissolved in nineteen liters of water in order to make the sterilizing solution. The solution has a rusty color that is used as an indicator of its viability. A change in color to more clear forms hints that iodine concentrations have subsidized. Failure to follow manufactures instructions will lead to a poor end product of beer.

Chlorine bleach is also a good decontaminator. It has been in use for a long time because it costs less than the rest. The normal laundry bleach will suffice as a sanitizer in brewing. It is also dissolved in water where a few milliliters are mixed with nineteen liters of water. However, chlorine is highly corrosive with other elements and therefore it should not be used as a post rinse agent.

A high temperature in the form of moist heat is the best sanitizer in term of killing all microorganisms present. Moist heat is generated inside pressure cookers with no outlet to decompress its inside chambers. Since moist is easily dispersible like a gas, it reaches out to every part that bacteria could be hidden.

The most effective chemical disinfectant is hydrogen peroxide. It exterminates bacteria in ten minutes by changing their cell composition. In the case where chlorine bleach is used, it is used to rinse the surfaces in order to get rid of the destructive properties of chlorine.

People who have been involved in the brewing process know that selecting the best brewery sanitizer is good for business. They appreciate the fact that it can effectively influence the outcome of a good batch. Having knowing this they can easily concentrate on other brewing procedures that can make their beer taste better.
