A Quick Quiz: Popular Bourbon

In celebration of reaching a milestone that I had set, I’d like to give away a copy of the book Whiskey: The Definitive World Guide by the late Michael Jackson.

The first person to answer the following question will win.

Jim Beam is currently America’s most popular bourbon. What brand did they surpass to gain that title, and in what year did that occur?

To make things fair, only one answer per person please.

UPDATE: As the guesses have been off by a wide mark, let’s allow up to four guesses, as long as they are in different comments.

UPDATE II: Someone in the comments came awfully close to getting the answer correct. I won’t say exactly how.

UPDATE III: We have a winner. it was in 1970 that Jim Beam overtook Old Crow.
