Gainesville City Council will hear a proposed amendment to the alcoholic beverage ordinance when it meets today for a regularly scheduled session. The amendment is designed to allow Growlers on Main, which serves draft beer to go in Flowery Branch, to open a new location in Gainesville. The amendment would set the definition for a growler — a sealed glass jug of draft beer ready-made to take home for consumption — and provide the parameters for serving samples of tap beers at the location.
