My brew buddy likes this (never tried it myself) and as my lagering fridge is sitting empty, I've decided to give it a go tomorrow. Also, it is a chance to have a crack at decocotion mashing for the first time!
So I've based it on the recipe here... http://www.homebrewtalk.com/f59/boston- ... pe-154371/ but translated into ingredients available here, in civilised units of measurement, and scaled up a bit (need to maximise space in my lagering fridge)
I've elected to skip the krausening thingy - I'll just lager in bulk, prime and bottle like I did my Pilsner, as that worked out fine.
I'm surprised at the grain bill - it is practically identical to my Sierra Nevada Pale Ale. Don't they have anything other than 2-row and crystal to brew with in the US???
I'd appreciate any comments/corrections, as it is all a bit of a stab in the dark. I'm a little unsure of the hopping schedule - don't folk normally bitter with Hallertau and use Tettnanger for aroma??? The decoction process looks managable, but again, if there is something wrong, please say so! Thanks :)
