Now, on to the point of all of this, the growlers themselves and what was available. The growler (aka the glass jug) is a one time purchase of $4 and then you pay to fill it up. After you finish your brew, bring back your old for a re-fill, they swap it out, and on you go. Not only does this insure you're getting some of the freshest beer to go (since you can't buy directly from a brewery in GA), but you're saving money by not having to pay for the brewery's packaging and shipping costs that normally get passed on to you. So we were able to pick up 64 ounces of Rogue's Old Crustacean Barleywine for $17 and 64 ounces of Terrapin's Monk's Revenge for $10! The other very cool bonus with growlers is you can take them with you on trips outside of GA where the breweries actually do growler fills.
