A collapse of several Glenfiddich distillery roofs in 2010 followed after weeks of heavy snow. The casks that included Oloroso and ex-Bourbon casks were exposed to sub freezing temperatures.
So as you do, Glenfiddich decided to bottle it! The spirit id aged somewhere between 12 and 30 years of age.
