Filtration can play a big role in various aspects of the beer making process. From removing particles and compounds for a clear look and taste, to helping ensure different styles of beer taste the same from one batch to the next, filtration plays a big role in the brewing process. Whether you own a brewery, are a home brewer, or are simply someone who lives to drink beer, here’s some insight as to how Strainrite’s filtration systems create great end results for beers of all kind.
From filtering incoming water to your batch of beer, to filtration at the final steps of beer packaging, Strainrite filters can be used in the following stages of beer filtration:
Filtering Incoming Water
Since beer is about 90 percent water, filtering the water at the initial stages of brewing can play a big part in the final product. The first point filters can be used in this process is when water is filtered to remove particles and sediment. We recommend a four-step filtration process inducing:
- EVP (Enhanced Vertical Pleat) to remove particles from incoming water
- The MAXX Trap for trap filtration
- The Madd MAXX to reduce the maximum amount of particles from entering your water
The Mashing Process
During the mashing process, milled grain is steeped in hot water, which activates malt enzymes and converts grain starches into fermentable sugars. Then, the mash is then separated into clear liquid wort and residual grain in a lautering tun. Finally, the wort will be transferred into a brew kettle, where the Strainrite NMO Monofilament Mesh Filter Bag is an optimal option to catch waste grain.
Filtration During Hopping
Hopping is a crucial part of the brewing process. Hops can affect the flavor of beer, make it more bitter, and affect the aroma of your brew. Filtration systems that can help in this process include:
- Strainrite NMO Monofilament Mesh Filter Bags catch boiling and finishing hops that are introduced during the brewing process.
- Strainrite’s Nylon Monofilament FCB (Flavor Concentrate Bag) reduce labor and material handling costs associated with dry hopping processes.
Cooling beer or “cold crashing” causes yeast and other particles to sink, which means beer can be moved into the bottling process without haze in the final product. We recommend the EVP (Enhanced Vertical Pleat) or the Madd-MAXX series’ MAXX-Flow MF for transfer before this process. After cold crashing, Clarity Cartridge line’s Fiber Maxx pleated filter cartridges, which effectively remove proteins and tannins that cause haze. For microglass fibers in a large diameter cartridge, Strainrite recommends the Madd-MAXX series’ MAXX-Flow GF and Madd-MAXX-GF.
Strainrite’s Fiber Maxx, MAXX-Flow GF and Madd-MAXX-GF also serve as an excellent final filter prior to kegging, bottling or canning, or as a pre-filter to final sterilizing filters. Brewers may opt for a final sterilizing filter just before final packaging Strainrite recommends the Clarity line’s Bev-Maxx and Bev-Rite cartridges. This polyethersulfone, pleated filter cartridges are specifically engineered to provide an absolute barrier against beverage spoiling microorganisms.
