Hey everyone, this is my first post so if my formatting is incorrect I apologize. I have a plethora of growlers left over at my house from a lazy drunk room mate who never returned them. I'm wondering if it's possible to use these growlers for bottling and secondary fermentation? These growlers have screw tops, but is there any other way to cap these suckers so they will be air tight, or should I just abandon the growlers and go with a traditional bottle set up? Thanks and have a great day.
