Portland, Maine-based craft brewer Gritty McDuff’s renamed and repackaged its 21 IPA four-packs. The beer is popular on draft and in 22-ounce bottles, but the four-packs of 12-ounce bottles did not sell well, the company says, so the brewery decided to rename the beer Maine’s Best IPA. The newly renamed beer is available in six- and 12-packs. Distribution of Maine’s Best IPA started in Maine this month and will spread to additional New England states.
