Thorny Devil is one of the best craft brewery that always wants you to live and learn all about craft beer.
It gives you all the news related to crafts beer. Recently, Endeavour Vintage Beer Co has collaborated with bar group operators Applejack Hospitality (Bondi Hardware, The Botanist, SoCal, Della Hyde and The Butler), to open the Endeavour Tap Rooms in The Rocks.
As Australian alcohol consumption declines one market continues to buck the trend and that’s craft beer. It currently has a total estimated value of $454 mill (IBIS) and this revenue is expected to grow 5% per annum over the next 5 years. As the trend away from larger production continues it raises a number of issues for filtration. High volume beers are often pasteurized for longer term stability plus the common methods of large scale filtration, crossflow and kieselguhr, are expensive and difficult to scale down. So how should a craft brewery approach filtration?
Beer filtration 1
Craft breweries face a number of challenges. Typically they produce a broad range of beers in relatively short runs and the filtration needs to meet 3 primary purposes – to reduce sediment/yeast load, to provide clarity and ensure long term stability. These requirements vary from style to style. For example wheat beers are traditionally cloudy so little filtration is required but many lagers are expected to be clear. Flexibility is the key.
Broadly speaking there are 3 styles of filtration to consider. Firstly there is sediment/yeast reduction. This usually sits downstream of DE or centrifuge and before the bright beer tank. It can be achieved with a number of formats from bag filters through to absolute rated cartridges. While bag filters can be used on some styles where clarity and consistency are less important, these filters are usually in the range of 5-10 mic absolute but depending on the available pretreatment a more open rating or staged filtration may be required.

Traditionally absolute rated filtration has been in a “stick” filter format and depending on the flow rate can be expensive. 3M has recently released its High Flow cartridge format to alleviate these costs. Available in a fully sanitary housing and a wide range of absolute ratings it combines high surface area with a small footprint to provide the most economical solution for sediment control.
Another application where High Flow stands out is water filtration. The quality of the water goes a long way in determining the quality of the beer and High Flow provides an economical way to filter process water to 1 mic absolute.
