Filtration is key to improving the quality and taste of beer in any setting. Whether individuals are making homebrew, pub breweries are making stock quantities, or large-scale beverage distributors are mass producing a line of beer products, the filtration is very similar. In today’s post, we are going to review some of the steps of filtration in the beer brewing process.

At Filter Sciences, we manufacture high-quality bag filter housing units that can be used in nearly every industry that relies on filtration to remove particulate. Our filter bag housings can be used in very high and very low temperatures without leaking or breaking the seal. If you are in the beer or brewery business, visit us online to see what we can do to improve the taste and quality of your beverages!

1. Filtration After the Mashing Processes

Mashing is the process of steeping mill grain in hot water to activate the malt enzymes and convert starches into fermentable sugars. In this stage, the mash is separated into the liquid wort and residual grain product. The wort is then filtered through a mesh bag filter system to catch waste grain as the wort is transferred into a brew kettle. It is in this filtration process that a quality bag filter housing system is important and can withstand high heats and monofilament filter bags ensure optimal particle removal.

2. Filtration For Clarifying and Finishing

At the end of the process, when the beer is ready to consume, it will be clarified and filtered one to two more times. Haze removal improves the clarity of the brew by reducing particles — which, if high-quality ingredients and effective filtration practices were used prior to this point, may be a non-issue. The brew is filtered to further improve clarity by removing sediments, yeast particles, and any grain or hops that made it through the previous steps. In the final step, a final filtration can be conducted as the beer is placed in containers for consumption. Some breweries skip the final filtration process, which is completely acceptable if the previous filtration efforts were effective.

At Filter Sciences, we are proud to manufacture high-quality bag filter housing units that are ideal for use in the brewing, distilling, and beverage industry. For all of your brewhouse filtration needs, visit us online or contact us for your custom quote.
