Cornell & Diehl Burley Flake No. 4 takes Burley Flake No. 3's basic makeup - white and dark Burleys with red Virginia added - and includes some rich Cyprian Latakia, which brings in deeper flavor, richer body, and a touch of smokiness. The mixture is pressed into cakes and sliced so you can prepare it however you prefer. C&D's Burley Flake No. 4 is a great cool weather blend when you want a robust smoke without being overpowering.
