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 that Carafa 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 out what 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 I couldn'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

It didn'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)
