Another superb dram released as part of the impressive 100 proof series from independent Scotch whisky bottler, Signatory. Distilled in 2015 at the Caol Ila distillery and matured for 9 years in a combination of 1st fill Oloroso sherry butts and bourbon hogsheads, then bottled at the Edradour distillery at 57.1% vol, un-chillfiltered and without any additional colouring.
