I've been told not to use screw cap bottles...I did anyway and aside from one that went skunky, I'm enjoying my first Porter without a bottle opener. Am I just lucky or should I be using different caps? or should I really not use them?
"Brew Ware, how to find, adapt and build homebrewing equipment" by Lutzen and Stevens says that it is fine. Many, many other books say it isn't. I think if it works for you, they're fine, just not ideal. How's that for an ambiguous answer.
