Gainesville City Council voted 4-1 Tuesday to approve an amendment to the alcoholic beverage ordinance that will allow Growlers on Main, a Flowery Branch establishment that serves draft beer to go, to open a new location in the downtown square. A second reading of the amendment is scheduled to be held at the council’s next meeting, April 1, and would take effect April 10. The amendment defines a growler as a “reusable, re-sealable and professionally sanitized glass jug used to transport draft beer off-premises for consumption.”
