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 not consistent. 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 boil separately 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 inconsistent even 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 hard against the screen. It seemed to work well as I got a lot more water out. I may need to retune my absorption.
• 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
