Raw materials
Energy savings | From today’s perspective, some of the individual stages in the beer production process are extremely energy intensive. Lots of breweries thus aim to save energy by integrating innovative technologies and concepts without having to suffer any loss of quality. Pulsed electric field technology provides a number of different approaches here.
Filtration
Despite being a well-established technology, beer recovery from surplus yeast is often overlooked by small and medium-sized breweries as something which is only feasible for the big beer factories, having outputs of many millions of hectoliters per year.

Focus on sustainability | NX Filtration is a global supplier of beer microfiltration membranes, which is fast gaining momentum as the preferred filtration process for beer thanks to its quality assurance, cost savings, and sustainable credentials. Founded by some of the original developers of beer membrane filtration technology, NX Filtration also offers unique nanofiltration membranes for treating water, recovering and reusing chemicals and water recycling. The strong focus on sustainability can also be seen at the Spanish La Zaragozana brewery, where NX Filtration technology has been successfully implemented.

Membrane technology | Alfa Laval, a world leader in heat transfer, centrifugal separation and fluid handling, has acquired Sandymount, a US-based beverage technology company with a unique and patented membrane technology to concentrate beer. The signing and closing date was December 31.
Filtration
Dealcoholization | In August of 2019, “Ghost Ship 0.5 %”, a pale ale with strong citrus notes brewed by the British brewery Adnams in Southwold, UK, sailed back to the island nation with the gold medal it earned at the World Beer Awards. The award rounded off a year of meticulous product development with the new GEA AromaPlus dealcoholization system.

Parker Hannifin | Brewers are being given the opportunity to trial innovative sterile filtration technology. Parker Bioscience Filtration , Bielefeld, Germany, has introduced free trial capsules for its Bevpor BR range of filters, enabling breweries to undertake taste and visual quality trials, and test the effectiveness of this filtration method.
Quality assurance
Clear enjoyment | Who would not enjoy a clear, cool beer? The authors hope that everyone can continue to simply enjoy it so they focused their research on an approach for monitoring and quality control in beer production based on optical scattering methods, with the aim of developing a simple and flexible measurement instrument for in-line monitoring. The instrument presented could be installed directly in product plants or vessels and used for checking CIP procedures.
Filtration
Fibres and perlites | The efforts to establish alternative filtering aids in precoating filtration have already extended over several decades. With its approach involving compressible filtering aids, Krones AG, Germany, has now successfully completed an upscaling project in the Schussenrieder Brewery.
Filtration
Malt quality | Against a background of increasing process automation and ever more stringent requirements for product quality, processing of raw materials with fluctuating properties depending on year and location is becoming more of an issue. With this in mind, the focus on process optimisation is, in particular, on bottleneck process steps such as lautering and beer filtration. Apart from improving process technology, raw materials, in particular malt quality, provide enormous potential for improvement.
Filtration
Waste-free | Filtering beer without any waste, and making processes efficient and environmentally friendly is no longer merely a brewing fantasy. Cross-flow filtration with ceramic membranes has what it takes to knock established competitive processes that use kieselguhr or polymer membrane off the throne. However, according to filtration experts Sonja von Lieres and Felix Ockert from GEA Group, Germany, other parts of the brewing process must also be rethought in general.
Filtration
Clear | Some years ago, bright beers with excellent haze stability were the norm primarily among the larger breweries. However, the consumer also expects the same today from mid-sized breweries. This article discusses why polyphenol stabilisation using polyvinylpolypyrrolidone (PVPP) is an effective solution for this purpose.
