LOUISVILLE, Ky. (AP) — The producer of Maker’s Mark bourbon is cutting — likely permanently — the amount of alcohol in each bottle to stretch every drop of the famous Kentucky whiskey. The alcohol volume is being lowered from its historic level of 45 percent to 42 percent — or 90 proof to 84 proof.

The brand known for its square bottles sealed in red wax has struggled to keep up with demand that more than doubled the past seven years. Distribution has been squeezed and the popular premium brand has had to curtail shipments to some overseas markets.
