Just to update on this recipe - I slightly undershot my OG and got 1.066 but it was my first brew that I monitored my PH, which I got to 5.4 at room temp. Now I'm wondering if this has been the secret key to making really awesome homebrew, because the first bottle I've tried is truly wonderful! On my first taste I didn't really know what to expect and thought "Whoah that's way too hoppy and bitter!" but as I sipped away at it, it just got better and better. Very hoppy but very balanced. Not a hint of 'Homebrew flavour' and I think I have to say, my finest brew to date. Never again will I underestimate the importance of PH!
