9/7/2020 4:00 AM over 4 years ago	-1	Yeast Starter	1.040	1.5 Liters			9/7/2020 4:22 PM over 4 years ago	Created a 1.5 liter starter so I can pitch a big 1 liter of starter into this high ABV beer.
9/7/2020 9:53 PM over 4 years ago	-1	Mash Complete	1.079	4.4 Gallons	5.35	152 °F	9/7/2020 9:53 PM over 4 years ago	Mash went alright. My false bottom bent a little and the bag kept getting stuck in the hose so the recirc slowed down. Overall, not bad for this much grain.
9/7/2020 9:56 PM over 4 years ago	-1	Pre-Boil Gravity	1.079	4 Gallons		170 °F	9/7/2020 9:56 PM over 4 years ago	Pre boil was a little higher than expected. Also, grain absorption was higher due to more grain. So I only ended up with 4 gallons instead of the 4.2 gallons as the recipe said. Will have to adjust for that during my next high ABV beer.
9/8/2020 12:32 AM over 4 years ago	+0	Boil Complete	1.104	2.9 Gallons		80 °F	9/8/2020 12:32 AM over 4 years ago	Boil was fine with normal additions as per the recipe. Added half a whirlfloc tab during boil to help seperate the proteins. However, due to the wort being so thick, it is taking a long time for the proteins to drop out.
9/8/2020 4:12 AM over 4 years ago	+0	Brew Day Complete	1.104	2.4 Gallons		68 °F	9/8/2020 4:12 AM over 4 years ago	Pitched 1 liter of yeast starter and aerated by shaking the keg. Placed into keggerator set to 68.
9/12/2020 12:18 AM over 4 years ago	+4	Other	1.023			70 °F	9/12/2020 12:18 AM over 4 years ago	Fermentation activity seems to have slowed down a lot so I decided to take a reading. Got down pretty damn far in just a couple days. Bumped up temp to 70 to encourage final attenuation.
9/13/2020 7:21 PM over 4 years ago	+5	Other				70 °F	9/15/2020 7:22 PM over 4 years ago	Moved beer into laundry room to free up ferm chamber and allow beer to complete fermentation.
10/1/2020 5:25 PM over 4 years ago	+23	Other					10/1/2020 5:25 PM over 4 years ago	Racked the beer onto the cacao nibs soaked in vodka. Added in the vodka as well.
10/30/2020 12:15 AM over 4 years ago	+52	Fermentation Complete	1.020	2.25 Gallons		70 °F	10/30/2020 12:15 AM over 4 years ago	Fermentation finished.
10/30/2020 12:16 AM over 4 years ago	+52	Packaged	1.020	2.25 Gallons			10/30/2020 12:16 AM over 4 years ago	Transferred to serving keg and place in keezer for carbonation.
