Seeking to discover if old barley varieties could produce unique new whiskies, the team will test at least eight heritage barley species, to investigate how they respond to modern processing techniques.
Varieties to be tested include the 200-year-old Chevalier, considered UK’s most popular barley for 100 years, from the 1820s to the 1920s; Moravia-grown Haná, which appeared in the first blonde pilsner lager in 1842; and Golden Promise, used in Scottish whisky brand The Macallan’s bottlings during the 1960s (BBC, 2023).
“There’s hope that using these heritage varieties of barley might allow for recovery of favourable aroma characteristics into distillate and some have also displayed potential resilience to stresses that might be expected in a changing climate,” says Calum Holmes, assistant professor of brewing and distilling at Heriot-Watt.
The researchers hope the results will produce new single malts for Edinburgh’s Holyrood Distillery, which, according to head of spirit operations Marc Watson, is particularly interested in the potential sensory differences and distinctive mouthfeel created by the revived barley varieties.
