I have great memories of many years ago filling Tawny into used whiskey barrels that had been imported straight from distilleries in the USA. As the Tawny went in, wonderfully rich whiskey aromas filled the air and when revisiting these barrels some time later, the old Tawny inside showed the distinct flavours of the spirit that had originally been in those casks. Added to that were the typical, beautifully aged rancio Tawny characters you'd expect to taste.
Some years ago we decided to relive this memory by importing a number of used Bourbon barrels from Kentucky, USA, and filling these with a special Tawny. These barrels have made a home in our dusty fortified shed and are maturing gracefully
