2013-11-17 Brew Day:

These are my notes. I was also bottling Brew 006 at the same time

(3:16) Start heating 3.7qt=14.8 cups. Just did 14.75
Heat to 165 for 152 mash
4 cups of room temp water ready to lower temp
overshot temp to 174. Wait to cool. Pulled a few cups and replaced with room temp
(3:38) Mashed in. Too thick in my opinion. Thinner next time!
Hit 152 exactly. Hold 15
T-45. Temp=149 but notconsistent. Heat on 3/10 while stirring. Took a while to 150 then jumped to 156. Hold 20 or so (finally at T-40 min)
I'm going to mix this up. I'll boilseparately 1.6 qt to infuse to 168 (a according to Brewers Friend). Then sparge with 4.4-1.6=3.8qt.
1.6 qt=6.4 qt=1514ml
T-18, Temp=152°F. Hold 10 or so
T-9. Temp=148 then dropped as I stirred..Need to investigate why this is so inconsistenteven with the heat.
Infused the water. Still had to add some heat.Why didn't the formula work? My two guesses are that some of the water had steamed away when I was trying to boil it. And that it may not have been boiling when I added
Used a newish technique to squeeze the bag. I used the silicon pot holders to push really hardagainstthe screen. It seemed to work well as I got a lot more water out. I may need to retune myabsorption.
4.4375 qt from first running (plus mashout infusion)
Heat on first run (5:00)
Hop Adjust: Horizon 0.11oz13% (recipe)/10.1%=14.1 oz. Amarillo: 0.25 oz9/10.1=0.22, 0.44==>0.39
3.75qt from second running
Preboil OG 1/049@55 and 7.8125 qt ==> 91% pre-boil efficiency
(5:23) boil!
Missed the 15 by 45 seconds.Also added Irish Moss and Yeast Nutrient
(6:24) Into Ice
6:37/95F. Lid on. Added more ice
Going to pitch the whole packet despite knowing 1/2 or so will die. I have more than enough still and I don't want to save it
6:44 75F. Pull it
1.061 @75 --> 1.062
Aerated. Sprinkled yeast. Stirred gently
15.6cm --1.48 gal
__6:54. Put away. Most cleanup finished too
BF says 88% efficiency
I wonder if I am risking other problems with such high efficiency. Also, what caused it?

2013-12-07 Bottle Log:

I had put the fermenter in the fridge on Thursday Night to cold crash (about 48 hours)

1.016 @ ~43F --> 1.015 and 6.17% ABV
12.35 cm 00> 1.12 gal or 4.49 qt
11.9 12 oz bottles so aim for 11 with large safety margin
Actually, with 4 oz H2O for priming could get 12ish. Plan for 12 in case
Carb to 2.4 vol but still not sure on temp.
If T=43F, 0.66oz dextrose, if T=68F, 0.93 oz dextrose
Plan for 0.75 oz which is 2.55 vol at 43 and 2.1 vol at 68
Filled 11 cleanly and just drank the last one.
3 weeks will be 2013-12-28
