Can you filter carbonated beer

To do this I usually disassemble the filter and soak the tubing, the filter housing, and the filter in a sanitizer. Step-by-step filtration: The flow rate of beer across the filter can be controlled simply by adjusting the carbon dioxide pressure at the regulator, connected through the CO 2 IN line of a standard Cornelius keg.

This valve lets me control the flow rate independently of the regulator, and if the beer is carbonated it allows most of the carbonation level to be maintained. It also reduces fobbing in the receiving keg. Once the filter is connected to the keg containing unfiltered beer, the filter cartridge can be filled with beer.

The filter cartridge can be bled off if desired; this can be useful if you want to purge any air that may be in the filter.

The receiving keg is then connected through the BEER OUT line, and the bleed valve is opened to allow the beer to flow through the system. It is always a good idea to fill the receiving keg through the BEER OUT line so that the keg fills from the long liquid tube — from the bottom of the keg up — to minimize agitation and possible aeration of the beer. Before filling, always purge the air from the receiving keg by filling it with carbon dioxide.

Once the receiving keg is sanitized and purged with carbon dioxide, pressurize it to 10 psi. Filtering requires that the filter elements fit tightly and maintain a good seal. A tight seal means that the flow across the filter cartridge will be even and laminar and also ensures that no oxygen is introduced into the beer in transit. You can monitor the effectiveness of the filter by disconnecting the BEER OUT line of the receiving keg and filling a glass of beer by hand.

I usually sample at the start of the filtering and again if the flow rate seems too slow. A slow flow rate could indicate that the bleed valve on the receiving keg is closed too much or that the filter is overloaded with yeast.

If the filter gets stuck, it must be backflushed to purge the yeast. I keep mine in a sealable plastic bag in the refrigerator with some weak B-Brite. Although crystal clear homebrew is not required for a tasty pint, it is sometimes beneficial to remove the yeast to clean up the appearance and taste of a beer.

Clear beer is the conquest of both haze compounds and yeast, each of which should be dealt with separately. Haze can be reduced significantly through brewhouse procedures. Cloudiness resulting from yeast could be due to the strain of yeast, the health of the yeast, and the amount of yeast pitched. Although home brewers have a variety of filter types from which to choose, the cartridge filter offers a cost-effective and efficient solution to producing brilliant beer.

Another change is that usually the source tank is on the first story of the building, along with the filter, while the receiving tank is on the second story. In this instance, both tanks are on the second floor while the filter is on the first floor. What differences can I expect from that?

As long as you watch the pressure very careful, there should be no problem. Hope this helps, Fred. Comment Post Cancel. I don't get it. Why would you vent the natural carbonation, filter still, and then carbonate afterward?

There certainly are advantages to preserving the natural carbonation and filtering under pressure. Both the fermenter and the bright tanks should be at the same CO2 pressure during the entire process.

Ensure this is the case by running a balance line between the tops of the two tanks. Being on a lower level, the filter will run at a higher pressure--so many feet of beer higher.

You could fill the hoses and filter with ideally deoxygenated water, add CO2 to make the pressure in the hose at the tank the same as in the tank. Replies 3 Views 1K. Jan 8, SimonHucko.

Make sure to connect the flush water source to the in side of the filter assembly.

After testing, you have a setup that can be used to filter beer and, with an appropriate shut-off valve and activated charcoal cartridge, one that can normally function as an under-sink or icemaker filter too.

The goal is to transfer unfiltered beer from one keg, through the filter, and into the final dispense keg without aeration or contamination. This is the kind of beer-handling challenge that makes home kegging systems such a joy.

Sanitize a second Cornelius canister, and purge and seal it as well. Finally, sanitize the filter assembly and the two transfer hoses used to connect the filter to the two Cornelius kegs. This can be done easily by filling the housing with sanitizer, installing the filter cartridge, and assembling the filter and hoses.

After an appropriate soak time drain the filter assembly out through the hoses, then connect all equipment. The airlock tube can be your picnic faucet tubing with the faucet held open with a rubber band. Put this tube into the airlock first, then attach the quick-disconnect to the dispense keg. After all equipment is connected, begin applying pressure slowly to the system while monitoring for leaks.

Minor leaks are just an inconvenience; you can tighten things up as the transfer proceeds. Hold the filter housing upside down. As the source keg empties gas will flow into the assembly, forcing the remaining beer through the filter.

When the transfer is complete, remove the quick-disconnect at the airlock side of the system first, then the quick-disconnect at the inlet to the dispense tank. Finally, remove the gas-in disconnect at the source keg and attach it to the gas-in side of the dispense tank. Pressurize the dispense tank as you normally would and start chilling. Procedures are basically the same for non-cartridge filters. You can also add adapter fittings to this filter as suggested for the cartridge units.

Filter manufacturers make all sorts of claims about filter lifetimes and the amount of beer that can be filtered with a single cartridge. A used filter allowed to dry out completely can become useless quickly depending on your water supply and other factors such as mold growth. One way to extend the useful lifetime of a filter is to backflush it after use. A backflush of warm water and completely dissolved TSP, followed by a complete cold-water rinse, can help tremendously.

In time you may find you have to use extremely high pressure to get any reasonable beer flow. If you already own a kegging setup or are planning to get one, filtration is a convenient process that will only make your equipment investment more versatile and slightly more expensive. One thing is certain: Because of the variety of equipment offered by hardware stores, mail-order companies, and homebrew supply shops, setting up a filtration system is easier than ever.

If you have a batch of beer that just won't clear, all is not lost. Use one of these fining agents.
