Brew 2013:09 - Milk Stout (2013-12-07)

I brewed a milk/sweet/cream stout using the recipe from Brewing Classic Styles. The only thing I really tweaked was that it called for Black Patent 525L and my shop's Black Patent was 625. However, I read thatCarafa III (525L) is also the same as black patent. So I used that.

The recipe and notes are below:

2013-12-07 Brew Log

Below are my notes. Note that I was also bottling the Brown Ale at the same time. Note that I did NOT have the grains double milled!

2:01 Start
4.4 qt to 162-163 for 151 mash
2 cups of water ready for cooling
(2:22) @162.5. Dough in. Settled to 151.1F
Note, new thermometer. Needs to be calibrated. It seems to be up about 1 degree (tolerance is +/- 0.9 so not too bad but could be brought in line). For today, I did the adjustment manually
t-40min: T ~148-149. Stir with 3/10 to 151-152.
Note: Temp jumped a lot. This thermometer is quicker. I wonder how not-mixed the temp was
Also note, I had wrapped the pot in a towel in addition to the normal towels for better insulation
t-18 min: Temp 149. Heat to 152. Hold
Heat 1.9 qt to boil for mash out
T-0; Temp ~149. Infused boiling water. Came to 162. Heat 4/10 to 165. Hold 10
3.1 qt sparge to 168
5.38qt first runnings+mashout.
Hops AdjL 0.41 oz * 5 %AA(recipe)/5.8%AA(actual)=0.35oz
3.125 qt second running. Total 8.805 qt
Pre kettle SG: 10.045@80--> 1.047 ==> 91% Efficiency
4:14 Boil
Added the "Late addition" lactose at 10 along with the Irish Moss and Yeast Nutrient. (Actually did at 9)
5:13 Into Ice
5:26 @ 88.5F (lid on). 5:36 @68.5F (Pull it)
1.070 --> 1.071
17.5 cm (WTF! Way too much) for 1.7 gal
Brewers Friend says 97% efficiency (now counting lactose)
Shook for a minute or so. Pitched yeast. Stirred.
Finished around 5:45

I need to figure outwhat is going on with my efficiency numbers. They really do not make sense. I checked the hydrometer and it reads correctly in water. I checked the volume and it is pretty darn close. Also, my boil-off was too low. I need to adjust these different things for next time.

Also, I am worried about the fermenter being so full but Icouldn't get my tubing to work as a blow off so it'll have to do. Hopefully it won't make too much of a mess

2014-01-06 Bottling

Itdidn't seem to need the blow-off. When I went to bottle it, there was krausen on the lid but only in a few spots. I got really lucky! Anyway, below is my bottling notes

Did not cold crash since it is such a dark beer and no real need
FG 1.025 (hard to really see with the foam so I guessed high)
Brewers Friend says 6.04%=6% ABV
14cm --> 1.30gal or 167 oz
That is 13.9 12 oz bottles. Plan for 11x12 oz and 1x22 oz
Aim for 2.5 vol with 60F as temp
Calculator says 1.07oz corn sugar (and I used 1/2 cup tap water)
