It is not known if peats derived from different areas of Scotland have distinctive chemical constituents that could impact on malt whisky in discernible organoleptic ways. Fourier transforminfrared (FT-IR) spectroscopy was used as a high throughput screening method to investigate discrimination of a large number of peat samples from six different geographical origins around Scotland. The data were analysed statistically (using principal component-discriminant function analysis) and the results showed a difference between peat samples from different geographical origins. Therefore, we have shown that FT-IR spectroscopy provides a quick and simple method for differentiating peat types. © 2006 The Institute of Brewing & Distilling.
