I've been buying a few screw top growlers from the store down the street from me,i had the bright idea to bottle in some to save some labor.Sure enough after bottling i read here caps can bulge,fly off or they will explode or not carb.The caps seem very tight fitting,think i should just wait it out with them in buckets incase of a disaster?...Or i could ked the gallon of beer if i had too.I'm leaning towards just monitoring them with welding gloves on and safety glasses lol.
