Newbie question, but how do you tell the difference between batches?
I've read all 10 pages and no info on this.
I bought 4 and all have hairline cracks but no leaks and are otherwise awesome.
Also, I am currently using cappuccino and redbull and cranberry flavors, I was going to buy cola, but there are posts saying this is not a good idea. Which flavors are acidic and which aren't?
Thanks!!
