You can absolute positively bottle and bottle condition with screw top 64oz growlers. Anyone who says you can't obviously hasn't
tried it and is giving an armchair answer. I know because I do it all the time. A lot. Over and over. You can, it works very well, and you you don't need to do anything differently when bottling. I use
these caps. I recommend them because I've
tried them and they work. These caps will not bulge as some people
speculate. Other things may work but I can't comment on them because I haven't
tried them. I hope this is the straight answer to the question. They carbonate at the same rate as 12oz bottles. (Great in 2 weeks.) I assume you could blow them up by keeping unsanitary conditions and contaminating them with bacteria or over priming but that can be said of any bottle.
Try it. Don't believe me? Just try 1. You'll see.
There is no reason to shrink wrap.
There is also the possibility that I've just been amazingly lucky the last (got to be near 100) times I've used them.
