Brighter, clearer beer could be on the way thanks to a superfine filter that owes its existence to the failure of a decade-old recording technology.<br />
<br />
In the early 1990s, Philips developed the Digital Compact Cassette tape format. DCC used record/playback heads that could write or read magnetic data through holes just 70 micrometres wide. While DCC failed against the might of the CD, a Dutch start-up called Fluxxion in Eindhoven has now adopted the hole-blasting technology to make a new class of fluid filters.<br />

The ultra-fine filter is a boon to brewers who need to remove cloudy yeast residues. To test the silicon filter, the Bavaria Brewery of Brabant in the Netherlands, gave Fluxxion cloudy barrels of freshly brewed beer to try filtering in the lab. The beer cleared so well that Bavaria installed its own pilot plant eight weeks ago.<br />
