The second release in Glenfiddich's Experimental Series is their Project XX expression, which was made not simply by one Malt Master, but 20! 20 Malt Masters were invited to the Glenfiddich distillery and invited them to pick any expression from the thousands of casks maturing in the warehouse. The 20 chosen whiskies were then married by Malt Master Brian Kinsman to create this single malt you see before your eyes.
