Wiser’s, Lot No. 40, Pike Creek, and Gooderham & Worts. His doctoral research focused on the interaction between wood and whisky during maturation, a study that has significantly influenced his blending techniques leading to the now famous “Dissertation” bottling from JP Wiser’s based on this thesis at Harriot-Watt University.
