BUT WHAT DOES IT MEAN!?!?! Ok, really, this beer is pretty yummy. I've had it both fresh and aged a bit (from when the hubby was deployed). It loses some flavor and gets much weaker as it ages. I'd definitely suggest drinking fresh if you've got one.
Oh and just in case you don't get/know the Double Rainbow joke, or just want a hilarious laugh, check out this video.
Check out the brewery's site for more info.
See if it's distributed near you and what others think at Rate Beer.
