In 1901, Philippe Meura developed the first mash filter for application in the brewing industry. Since then, over 1,000 Meura mash filters have been installed worldwide. A major advance was made in 1989 with the introduction of the Meura 2001®, a thin-bed, membrane-equipped, mash filter and today more than 20% of global beer production is produced through a Meura 2001® mash filter. The fact that this share continues to increase every year is a strong statement of the confidence today’s brewers have in Meura’s mash filtration technology!
Since the introduction of the Meura 2001® mash filter, considerable research has been conducted comparing the wort coming from lauter tuns and the wort coming from Meura 2001® mash filters. Mash residence time in the vessel, extract yield and wort brightness are all parameters that are easy to evaluate and clearly favor the Meura 2001® mash filter.
Flavor stability is also enhanced with the mash filter. Research by Meura Technologies and independent researchers clearly shows that due to the shorter sparging cycles and lower sparging water ratio (as low as 2.3 l/kg over a 40 min. cycle) with the mash filter, the leaching of polyphenols and nonenal-potential is reduced and flavor stability enhanced.
The Meura 2001® mash filter is the only technology that guarantees and simultaneously delivers the following performance. This includes the craft brewer as well as the industrial producer.
There are other advantages to the Meura 2001 mash filter which might be of particular interest to the craft brewer:
