Using the SWRI laboratory stills, we studied the role of copper in removing sulphury notes from spirit and determined the parts of the still having most significant impact. Knowledge gained from this work has subsequently been applied in industry, with certain distilleries installing interchangeable copper and stainless steel condensers to achieve different styles of new make spirit. Results of the study were published in the Journal of the Institute of Brewing The Impact of Copper in Different Parts of Malt Whisky Pot Stills on New Make Spirit Composition and Aroma
