In October 2017, master distiller Billy Walker acquired Glenallachie and breathed new life into the distillery. Besides adding his trademark capital letter in the middle of the distillery’s name, he introduced a new core range and limited releases. Glenallachie 13 Years Old Single Cask 2006 is a limited-edition single cask bottling, specially selected for the 10th anniversary of ralfy.com, the website of popular whisky reviewer Ralfy Mitchell. The whisky was distilled on 19 April 2006 and matured for 13 years in port pipe #866. It was bottled in May 2019 at 59.9%. Only 890 bottles of Glenallachie 13 Years Old Single Cask 2006 have been released.
