Had a crack at my first partigyle (w00t!).
Russian Imperial Stout + an American Stout.
Ended up with ~30L of 1.104 RIS and 23L of 1.059 stout, so yeah, pretty happy about that
I didn't really have much idea on how this was going to pan out... general idea was to dial up a RIS at 70% eff instead of my usual 80%, but then up the grain amount by another 5 to 6kg to cater for the second beer (both ballpark same volume). For the RIS, I had planned to use the first runnings, and then potentially add some second runnings in if needed even if it meant a much longer boil. Turned out I needed to dilute the first runnings (~1.105) with both some of the second runnings and straight water to get the preboil OG and volume. I didn't even bother planning IBU's or hop additions for the second runnings batch until I had filled the kettle and knew the OG.
Grain Bill
----------------
16.000 kg Pale Ale Malt (71.46%)
2.000 kg Munich I (8.93%)
1.500 kg Brown Malt (6.7%)
0.900 kg Roasted Barley (4.02%)
0.600 kg Chocolate, Gladfields Light (2.68%)

0.500 kg Wheat Malt, Roasted Dark (Briess Midnight Wheat) (2.23%)
0.390 kg Black Malt (1.74%)
+ 0.4kg CaraMunich 2 added to the mash for the second beer.
Bit of a bitsa grain bill but there was the roasts, black and one of the choc's to use up.
RIS was Magnum & EKG for bittering (55ish IBU), 2.2g/L Chinook flowers & 0.9g/L EKG late and 1.2g/L EKG in the cube for 85ish IBU total.
Stout had 32 odd IBU from Columbus for bittering, 2.4g/L Chinook & Cascade flowers @10 for another 28 IBU, then 0.6g/L Simcoe at flameout and 1.6g/L Centennial/Simcoe in the cube for 80IBU total.
Stoked with how well winging it turned out.
