The Singleton brand is actually manufactured in three Scottish whisky distilleries; one of which is Glendullan. This 15 Year expression, along with the other expressions from the Singleton lineup (a 12 and a 18 year), was released in the US in 2017.

Singleton's 15 year old single malt scotch whisky is matured in a high proportion of American oak casks with a small portion of European oak casks to balance the liquid. The result is an easy to enjoy single malt with a fruity decadence and notes of zesty coriander, zingy pepper, honey and creamy toffee.
