I use any size bottle, small or big to bottle condition...I just add sugar according to the volume of the bottle, it works great. Some times I'll bottle the whole 5 gallon batch into all 2 litter growlers. It usually takes about 9- 2 litter growlers to bottle all 5 gallons.. I have about 35-2 litter swing top growlers and about 40 1-liter growlers.. I like to age beer in these bulky bottles. I bought mine here when they were about nine dollars a bottle. http://www.breworganic.com/2literswingtopgrowlerwithhandlecaseof6.aspx
I've never encountered a problem using swing top 2L growlers. I've aged high gravity beers for years in these growlers, and as one would expect from any good bottle, I've only experienced great bottling results using these growlers. By mistake, a couple times, I did over carbonate some batches, and when that has happened in the past the swing top growlers did not explode like regular capped bottles, instead the gas leaks through the rubber seal. I guess you can look at it as a safety release valve, idk.
By mistake, an over carbonated brew. I opened the cap, released some pressure, let it age for a year or so, drank it, and all was good. I don't do that often.
