PBW (Powdered Brewer Wash) is an alkaline solution that has recently gained popularity, especially in home brewing. It is a strong yet gentle cleaner used to clean brewing equipment without leaving any residue. Yet, how much PBW should I use per gallon, and what do I do after cleaning?
How Much PBW Should I Use per Gallon?
1 to 3 ounces of PBW per gallon is enough to clean the brewing equipment effectively without damaging the surface of the brewing material. Don’t worry about measuring the ounces; you probably have the equipment. The best tool is the tablespoon. 2 tablespoons are equivalent to 1 ounce.
However, it is essential to take caution when using the cleaner. Always read the instructions carefully before using them. In the process of mixing the PBW with water, you will notice the formation of foam. This is normal; however, you should not use too much as this could create a thick foam that will clog your sprayer.
How Does PBW Work?
PBW is an alkaline solution that works well when mixed with warm water to clean brewing equipment such as fermenters, brewing kettles, and bright tanks. The cleaner works by chemically breaking down dirt particles stuck on the surface of brewing materials. This makes it easy to clean the equipment without much scrubbing.
After cleaning, it is advisable to rinse the equipment thoroughly using non-rinse sanitizer. You can also use cold water since it has a minimal reaction with the cleaner. Rinsing ensures that no residues of PBW are left behind in your brewing equipment, as this could alter the flavor of your beer.
When using PBW, it is essential to be extra cautious. The cleaner is strong enough to corrode metal surfaces when used for extended periods or in high concentrations. Read the labels carefully and follow their instructions to get the best results.
What Happens When You Over-Dilute PBW?
Over-diluting your PBW will automatically reduce its effectiveness, resulting in equipment that needs to be thoroughly cleaned. Remember that the PBW helps to loosen dirt and grim in the brewing kettle, not water.
Therefore, to ensure effectiveness, an optimal dilution is recommended. This will help you achieve the best cleaning result and maintain your intended beer flavor. No brewer wants to ruin a good batch of beer due to the wrong dilution process, and over-diluting PBW is one of the major causes.
