The distillery behind Maker’s Mark bourbon is reducing the amount of alcohol in its bottles to meet a rise in global demand, company officials said yesterday.

“Demand for our bourbon is exceeding our ability to make it, which means we’re running very low on supply,” Maker’s Mark executives Rob Samuels and Bill Samuels Jr. wrote in an joint e-mail to customers.

The bourbon brand — which in the ’60s and ’70s famously used the slogan, “It tastes expensive . . . and is” — looked at “all possible solutions” and “worked carefully” to dilute the potency of its product while maintaining “the same taste profile.”

Maker’s Mark is currently distilled to 45 percent alcohol by volume — or 90 proof — and will go down to 42 percent ABV — or 84 proof.
