Auchroisk distillery is a whisky distillery in Banffshire, Speyside, Scotland. It was established after Dorie's Well was discovered and found to have water similar to the water used by the Glen Spey distillery, which was used by Justerini & Brooks to produce malt whisky for their blends. The well's water was used to produce a test batch of whisky at Glen Spey distillery, and was approved, which led to the start of construction of the Auchroisk distillery at the site of the well in 1972 to produce whisky for the J&B blend.
