Mt. Carmel Brewing Co. has returned to its roots by once again offering half-gallon growler sales. The move has delighted customers who remember when the Cincinnati-area brewery first opened about six years ago and sold in growlers only and not bottles. Mt. Carmel officially started offering its Snapshot Series, basically one-off and higher alcohol beers, in growlers at the brewery just two weeks ago. If a particular Snapshot beer runs out because of demand, the brewery will then offer whatever seasonal is available at that time, such as Winter Ale during the winter. "We've got people knocking down our door," assistant brewer Patrick Ian Clark said. Some customers have even brought in original Mt. Carmel growlers that were used years ago. "The growler has opened up the door to some fond memories of Mt. Carmel," Clark said.
