I stumbled upon the brewers notes for this on another forum, they were really quite detailed and so the recipe I'm really happy with. I substituted vanguard hops with Hallertau, because GEB nor anywhere else for that matter stocks vanguard. Used 37 litres water in total and ended up with 30.5 in the boiler, a little too much but preboil gravity was still 1.064. Mash ph 5.8. Boiled for an hour and a half in the end to reduce the extra volume and got about 26.5 litres post boil. There were a lot of leaf hops added at whirlpool, I can't wait till I've finished using the last of my leaf, it's a pain in the **** to clean up frankly, nevertheless put exactly 23 litres in the FV. Happy with that, OG was a little high at 1.078, worked out at 89% brewhouse, pretty standard now looking back at my notes, apart from one rogue brew. Noticed a lot of wort going down the overflow at first even though I mashed in really thoroughly, so I raised the malt pipe after thirty minutes and gave it a good stir, the bottom of the grain bed was very tightly packed. I'm certain now that torrified wheat causes this, it seems to swell up slower than everything else and closes up the grain, anyhow the stir sorted it nicely. Pitched 2 packs of S05 and fitted a blow off tube which I've never done before, I'll be interested to see how it ferments out as I've used CML yeast on all my AG brews so far, also there's a touch of peated malt in this it'll be interesting to see how it adds to the taste. My last RIS was a partial extract that was extremely roasty after 3 months conditioning but now it's excellent 9 months bottled and two dozen left. I plan to keep a pile of this one for the medium term as well. Hoping tomorrow night not have a brown brain in my brewfridge!
