hehe... indeed. my favorite right now actually. if you're able to get some of that hopportunity knocks from a local distributor, you should definitely check it out. they recently started putting it in 22oz bottles so there's a good chance you could get some. it's even better than the IPA. sadly they don't offer any stats for that one.
with respect to working backwards on the IPA, i'm going to have to leave that to someone with some actual skill! LOL. i'm a super newb at this point and will be lucky if my first batch is drinkable!! hehehe.
if you decide to give it a go, definitely let me know how it works out. would love to make some at some point.
