Environmentally-conscious beer drinkers can now reduce their carbon footprint,thanks to a new brewing technique.The method saves energy and reduces waste by using violent steam blasts to speed up the brewing process,New scientist magazine reported.It is used at the energy-intensive "wort boil" stage of beer-making when hops are added to liquid containing malted cereal grains.In tests over 2 years at Coors brewery in Burton upon Trent,Derbyshire, it was found to cut wort boil energy consumption by 40%.The new technique,called PDX and developed by Pursuit Dynamics,based in Huntingdon,cambs,involves blasting steam at supersonic speeds into the brewing vat...Jens Thorup,Persuit Dynamics's technical director said:"The steam rips the liquid apart completely to form tiny atomised droplets.The droplets create a massive surface area that speeds up brewing reactions"..Brewers Shepherd Neame,based in Faversham,Kent, and Carlsberg of Denmark are now set to adopt the PDX method,the magazine reported.

Say what you mean Dil! :o)

What was the point of starting another PDX thread, blueface? The other one getting too hot for you?
