LOUISVILLE, Ky (WHAS11) -- Kentucky's bourbon business is booming.
The amount of bourbon produced by Kentucky distillers last year topped one million barrels for the first time in 40 years.
The last time the total went over a million was in 1973.
The Kentucky Distillers' Association says distilleries are experiencing double-digit sales growth and seeing landmark production levels.
The group says bourbon production is up more than 120-percent since 1999.
