Four hundred seventeen years ago today, Mary Queen of Scots was beheaded after being caught in a plot to murder her cousin, Queen Elizabeth I. To celebrate (I never did like Mary), here's a roundup of confusing AP entries:

scotch barley, scotch broth, scotch salmon, scotch sour -- all lowercase scotch.

Scotch tape -- upper, of course, because it's a brand of tape.

Scotch whisky -- A type of whiskey distilled in Scotland. You Capitalize Scotch and spell it whisky only when the two words are together. Lowercase scotch when it stands alone (I need a scotch). And spell it whiskey for generic references to the liquor.
