Added yeast nutrient, didn't bother with whirlfloc since this beer is jet black anyway. New 15 gallon kettle was less nerve-wracking for boiling this one...I didn't care for the boil performance using the 33cm basket, so I pulled it when I added the secondary hops. Preboil gravity was 1.084. Loving the brew hardware whirlpool device. Hard to deploy sous vide probe in the 15 gallon kettle during mashing. Couldn't simply drop in brewing bags since this kettle has no false bottom, and the 33cm basket is out of space at 18 or 19 lbs of grain. Had to split the mash back into 2 and use the 33cm basket and the smaller basket...but they worked ok.

Notes

I set the efficiency down to 55 percent for a High Gravity brew but then considered using Reiterated Mashing. I split the grain in half, except for putting the Chocolate / Roasty grains in the second.
I've had the bourbon and chips started for 3 weeks. I added a little Fireball to up the cinnamon character - about 2 oz added when the devil's cut was consumed by the mocha chips - I also heated the mocha chips to make them more aromatic. Add the chips and all the bourbon after fermentation. BTW - Some suggest to toss the Bourbon that soaked the chips to reduce the tannins...if you do that, you will need more Bourbon to taste.

Last time I used Reiterated Mashing Techniques and it was a way more sedate brewday. This time I am using a 15 gallon kettle and a 33cm grain basket. I hope all the grain fits in that basket...if so, it'll cut the brewday in half, timewise. I can still put excess grains in a bag to finish the mash - doing so doubles the time to extract and will make me need hot water to sparge.

I am removing the DME (did not need it) and replacing it with Swaen Brown Supreme - 1lb...this should help with the body thinness and head retention and round this beer out further. Added 1 lb of rice hulls to help with circulation.

Ended up 67% efficiency. Didnt use the DME at all. Finished the brewday, Aerated with 2 minutes pure oxygen, used 1 tsp of yeast nutrient, 1 whirlfloc tablet. Get the bourbon and start preparing the wood chips 9/18/2023.

Larry used REDEMPTION Pre-Prohibition branded bourbon.
I am considering several, including
Wild Turkey 101 - Cheap but burny - might do well in a RIS.
Makers Mark 46 - Supposed to have a complex vanilla taste
Jefferson Reserve - Uh, breaks the bank but NICE
Buffalo Trace - Vanilla, Mint, Molasses
Bulleit KSB - Rye forward
Eijah Craig Small Batch 1789 - Vanilla, Nuts, Molasses, Sweet

Time to go get the bourbon (I chose EC 1789) and put 4 oz with my LD Carlson Mocha Oak chips so they can booze up until it is time to secondary.

Fermentation: Nothing much in first 8-10 hours, after that, I got a finger of Krausen and fermentation kicked into high gear...steady stream of CO2 in my blowoff vessel. Maintained for 5 days, then it slowed. Fearing a stall, I ramped the temp to 65 and later to 67. I get a burp of CO2 every 30-40 seconds now (Day 8) and I have a nice bed of sediment and clear dark beer. I ramped to 70 for 3-5 days to ensure complete attenuation and I will grab an F.G. sample at that time. Sample tested with hydrometer: F.G.: 1.021.

This is the fifth brew of this beer. I will use Nottingham since it's what I have on hand. My greatest issue is I don't want a yeast that will dry out the beer too much - Notty is badass and will ferment a truck if left in there long enough. Alcohol content is high enough to prevent that, I hope.
