Single malt is a Scotch category. “Double malt” is not. The 2009 Regulations list single malt, single grain, blended malt, blended grain, and blended Scotch. Johnnie Walker Double Black’s “double malt” line is marketing — the US page prints 40% and blended Scotch (prior this project). Glenfiddich 12 Year Old US prints 40% / 80. A 1.5-ounce pour at 40% is one NIAAA drink. No winner or ranking.
