It seems that a new method for brewing beer that allows energy consumption in the process to be cut by 40% as well as reducing waste produced. The method, was developed by Cambridge-based company Pursuit Dynamics. According to New Scientist Magazine the PDX method blasts steam at supersonic speeds into brewing vats to speed up the brewing process, according to New Scientist magazine. It is used at the energy-intensive "wort boil" stage of beer-making, when hops are added to liquid containing malted cereal grains. "The steam rips the liquid apart completely to form tiny, atomised droplets". "The droplets create a massive surface area that speeds up brewing reactions.Carlsberg are among others may soon begin using the process". says Jens Thorup, the technical director behind the process. Also adopting the technique are Sheapards Neame, and Burton.

My obsession today is IPA Beer, what is it and what are it's origins.  Why will you fall over drinking American Pale Ale rather than British and why is it still popular today in Bengal.    read more »
