We just heard from the guys at Charleston Beer Exchange that starting today at 11 a.m., they’ll be offering 64-ounce growler fills of SweetWater Waterkeeper Hefeweizen for just $8.99. And for every growler you fill, two dollars of your purchase will go directly to Charleston Waterkeeper. You’ll also get a free SweetWater pint glass.

CBX says that they’ve got a good stock of beer but they don’t know when it will run out, so you might want to grab those growlers soon.

UPDATE: The CBX guys say the special is still available as of mid-day Monday.
