Singleton of Auchroisk 10 Year Old 40% from 1990s (70cl, 40%)
These bottlings were actually the first to be labelled under "The Singleton of" banner, however they were eventually discontinued in 2001, with Diageo re-introducing Auchroisk as part of the Flora & Fauna series instead. The company would later revive The Singleton brand in 2006, but Auchroisk was overlooked, giving way to the trio of Glendullan, Glen Ord and Dufftown instead.
These early Singleton of Auchroisk releases were matured for 8 years in bourbon wood before being finished for a further 2 years in sherry.
Auchroisk distillery was built by Justerini & Brooks in 1972 to provide malt for their blends. Despite this, there was an immediate focus on its single malt as well, and it was first bottled in 1986. These were vintage-dated releases, and some of the earliest to use cask finishing. This was never advertised though, and the distillery left Balvenie to take the credit for the innovation.
