Update on the peat (since we're off-track anyway): 11% of lightly peated whisky malt hardly showed up in the 1.090SG wort. It may still come through as the whole thing matures, which I for one wouldn't mind.
I realise peat is a polarising flavour, leading people to either diss it completely, or go nuts with it. Siding with the latter camp, one of my next projects will definitely be an all-out 100% peat brew. With Islay-oak. Hah!
Turns out there's quite a bit of variability in the peated malts, and few producers actually note the ppm on the packaging. Bhat being said: err on the side of caution if you're not sure you like peat in beer. If you know you do, go for it. Make it waft.
