LOUISVILLE, Ky. (AP) — After backlash from customers, the producer of Maker's Mark bourbon is reversing a decision to cut the amount of alcohol in bottles of its famous whiskey.

The company's chief operating officer said Sunday that it is restoring the alcohol volume of its product to its historic level of 45 percent, or 90 proof. Last week, it said it was lowering the amount to 42 percent, or 84 proof, because of a supply shortage.

The brand known for its square bottles sealed in red wax has struggled to keep up with demand. Distribution has been squeezed, and the brand had to curtail shipments to some overseas markets.
