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.
Plan to use about 6 oz of bourbon - prepare 2-4 oz in a small jar and immerse the oak chips during fermentation. 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'll need more Bourbon to taste.

Use Reiterated Mashing Techniques? BTW - I had every kind of issue with the second mash in. It just ran super slow - all the oats and a pound of debittered black wheat...it took like 3 hours to do a 1 hour mash since I had issues with the runoff starving the pump, so I kept on stirring and all that. It worked, but I really, REALLY worked for it.

Ended up 67% efficiency. Didn't use the DME at all. Finished the brewday, Aerated with 2 minutes pure oxygen, used 1 tsp of yeast nutrient, 1 whirlfloc tablet. I'll get the bourbon and start preparing the wood chips 2/12/2022.

Larry used REDEMPTION Pre-Prohibition branded bourbon.
I am considering several, including
Wild Turkey 101 - Cheap but "burny" - might do well in a RIS.
Maker's 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.

Purged the Secondary with CO2. Problem: I am using the Big Mouth Bubbler with the depth charge. One - it's hard to get the beer in it without making the purge pointless. Two - I can get the oak out of solution anytime I want, which is nice. Three, I found a way to "re-purge" using the spigot and a length of tubing, so, after I added everything - I cleared the headspace with more CO2.
Now for 10 days bulk and I will pull the wood. Finally 6 weeks in secondary...then keg/bottle.
Placed in Secondary 2/25/22 with chips and bourbon - ended with 4.5 gallons.
