A German manufacturer of brewery equipment has joined with a Luxembourg beer brewer to commercialise a technique that they claim can save 55% of the energy required for boiling wort, a major process in beer production.

Steinecker Maschinenfabrik and Bofferding Brasserie Nationale have won an EU European Business Award for the Environment for their Merlin process which reduces evaporation in wort boiling from the usual 8-11% to  3-4%.

The companies say that the use of moderate boiling conditions means that water consumption, cleaning agents and waste water are reduced and the quality of the beer is improved. This has "enormous potential world-wide," they say.
