This is in honour of @Cloud Surfer who inspired me to get around to brewing a Russian Imperial. I eventually landed on my AG recipe:
OG 1.092
FG 1.021
ABV 9.6%
IBU 79
BU:GU 0.88
Using:
10kg Maris Otter (Crisp)
190g Crisp 240L crystal
190g Weyerman Carafa Special II
190g Simpson's Chocolate
190g Joe White Roast Barley
464g (1 pack) D180 Candi Syrup
I factored for a reduced efficiency of 55% as a rough estimate.
Hops:
75g Challeneger (8%) FWH
75g EKG 4% 30m
Yeast: 2 packets Nottingham
Mash:
69c 90m
76c 10m
So, I got strike water to temp, milled my grains and adjusted water for a "Black Ballanced" with a target pH of 5.5 as I don't top mash the roast grains and prefer a slightly higher mash pH for roast grains to keep the astringency lower.
Considering I was doing this in a Guten 40L, I realised it was gonna be tight. Very tight. So I mashed in, however I couldn't fit all the grain in. Literally had it to the holes on the side where the handle goes. Was maybe less than 1kg of grain, so figured I would boost it with a little DME.
All going well, but it was VERY slow to circulate. Like pretty much non existent. Decided to check mash temp using probe thermometer.... 60.2c ahhhh fark.
Luckily doughing in warm should have gekatinised some of starch. Oh well, what can I do. I know! I'll do a decoction to raise the temp. So off I scooped about 5l of thick mash, and into a pot. Bring to a boil, simmer for 5 minutes.
Hey look, my grain bed compacted, the wort isn't recirculating and is flowing over the sides of the malt pipe with all the grains. Awesome.
About 15m left in the mash. Stuff it, lift the malt pipe and scrape the bottom. Get some flow. Stir in the hot decoction. Back down goes the pipe.
Backing up again. I won't be able to raise the temp of the mash for a mash out. Stuff it, no mash out this time then. Lift the malt pipe. No good. Stuck. Stir like a mad man, sparge in 2L batches and let sit for a few minutes then stir and scrape the bottom to alleviate stuck mash.
Figured efficiency would be out the windows, so I could at least make a very expensive normal stout. Probably end up quite dry seeing I mashed a fair while at 60c.
Sparge to pre boil volume. Huh. Hit my estimated pre boil gravity.
Forgot to check mash pH. Ahhh biscuits. Oh well, on with the boil then. Cranked it up, measured the hops out. In they go. Not quite FWH but what ever. Close enough.
Bring to a boil. Start the timer. 20m to go, chiller in. Whirlfloc in. Nutrient in. Am I missing something? Nah all good.
Hook up the pump turn it on. All is good. 10m to go. Oh man, the EKG at 30m. Biscuits. Measure em out, got them in at 6m. Great.
Pump blocked. Never happened before (I use an external magnetic pump for whirlpooling)
Give the silicone hose a squeeze to try unblock. Manage to pull the hose off. Forgot to put on a clamp. 100c wort splashing all around. Shut off valve. Lost about 2L on the floor. Pump bubbling up hot wort. Didnt take whirlpool arm out, it's started to siphon. More hot wort on the floor, walls, guten, me. Great.
Start cleaning the mess up. Boil finished. Turn off the heat, disconnect the pump. Had a small 30 second cry. Get back to it.
Turn chiller on. Forgot to add D180. Quickly add it. Chill wort. Clean up giant mess in garage.
Transfer to fermenter. Add yeast. Thank goodness that's over. Check gravity. 2 points up and still managed 21L in the fermenter.
Faaaaaark. Next time, I am doing a reiterated mash. No questions asked. No chance I'm trying this again in one go.
