A few questions
-What size is ideal for a growler considering refill cost, and if you are just using it to bring home a beer not available in any other form of packaging
-Does it have to be glass, or will thick plastic or aluminium do the trick for you.
There are other options out there RE; size, cost and durability. Personally I don't trust myself getting home with a 3L glass bottle, I'd rather something that took a knock or two.
