Also known as Innis & Gunn Winter Treacle Porter Oak Aged Beer
Commercial description
Bottled, 2012 edition
This is the first time we have brewed and oak matured a Porter, which has been imparted with great depth of flavour thanks to the addition of some roasted wheat, crystal malt and molasses (rich, dark treacle). These flavour packed ingredients, along with our long, slow signature approach to maturation, have created a sublime beer that is perfect for cold, dark winter nights.
