I am off to start my 3 week long Grolsch drinking phase for them swing tops! Enjoy your Sunday!
What dedication to your craft! I have about 4 cases of Grolsch bottles, so I know what you're going through. (Grolsch isn't too bad if you drink it VERY cold).
I found that I actually loved Sam Adams, and they have great (non-swingtop) bottles that the label comes off of easily, so that was easier to take than the Grolsch.
