Yesterday I brewed 10 gallons of a completely new recipe that I came up with after researching stouts, chocolate additions, etc. From what I can tell, it turned out as well as expected. My end gravity ended up being lower than I expected, but by how much I’m not sure. I use an Iphone app called BrewPal, which works very well. If I go by their numbers, I hit my number right on at 1.056…but I’m not confident that’s correct with the additions I made. Either way, here is a general idea of what I did and how things went down.
Everything started great, I milled my grain:
17lbs of Pale Malt
1.8lbs of Chocolate
5oz of Roasted Barley
1lb of CaraPils
While milling my grain, I was heating my mash water. I ended up mashing 7gallons in at 165, coming to 156 in the mash tun. Over the hour of mashing, I lost about 2-3 degrees of temperature, ending at about 153. I mashed off about 4.67 gallons of wort before sparging. I sparged 8 gallons at about 179-180, coming to about 174 or so. I sparged off about 7.34 gallons, giving me 12 gallons into the brew pot.

The sweet smell of mashing wort
The color looked to be very dark brown but not quite black and smelled great. I was going for a roasted smell but didn’t want a strong coffee scent, even before my boil additions.

Close to black, but definitely dark brown
After running off a total of about 12 gallons, I collected a sample…which was later spilled as a friend grabbed a beer from the fridge. So…no pre-boil sample ended up being my first small issue.
Before I even started my boil, I mixed my baker’s cocoa. I wanted to prevent lumps, so I decided to mix 12oz of baker’s cocoa with about 1/3 of a gallon of COLD water. I decided to do this for a couple of reasons: 1) I’ve read about people having big issues with adding bakers cocoa to the boil…tons of lumping 2) after reading about these issues and others, I wanted to find a way to make it into a syrup type substance, so I decided to treat it like I would flour…mix with cold water…mix the water into the powder. Overall, the mixing went as well as it could. I slowly mixed the water into the bakers cocoa and came out with a very thick substance that looked and smelled almost exactly like a ready to go brownie mix.

Smelled great...tasted like garbage
After preparing the bakers cocoa, I measured out my hops:
.6oz of Magnum at 60min
1 oz of Willamette at 30 min
Now onto the boil. Once I got the wort boiling rapidly, I added my Magnum hops first and foremost. About 5 minutes into the boil, I added my chocolate bars…5 small bars of Moser Roth 85% Dark Chocolate. The 5 bars totaled 4.4oz…which I broke into very small pieces and added to the boil while stirring (to prevent any scorching on the bottom of the boil pot). In addition, I added 1lb of cane sugar to reduce some body a bit and add a bit of alcohol.

This says 70%, but I used 85%...I'm eating this 70% as I write
During my 25 minute off time (until my next addition), I measured out my lactose…22oz total. I followed that up with another beer and an ultra competitive game of bags with some friends.

My neighbor Krista...whose team was losing about 12-0 at this point
At the 30 minute mark, I added my 1oz of Willamette hops while continuing to stir occasionally in case any chocolate from the bars settled to the bottom of the brew pot. At 15 minutes I added 2 TSP of Irish Moss followed by my bakers cocoa mass at 10 minutes. I slowly poured the bakers cocoa into the brew point…which works rather well as I stirred. Once the bakers cocoa was mixed in, we all simultaneously agreed that the wort smelled of chocolate heaven if there is such a thing. At about 8 minutes, I mixed in my 22oz of lactose, making sure it didn’t clump.
At that point, my process was the same as always…crash cool the brew with my copper wort chiller, siphon into my fermenters (2 plastic ale pales in this particular case), pitch my re-hydrated yeast (Nottingham dry yeast), and close the buckets up with air tight lids with an airlock.
Overall, I must say the day went well. The wort smelled excellent and tasted very chocolatey without being too bitter. A few things that didn’t work out well:
-My pre-boil gravity reading was spilled all over my fridge…thus no reading taken
-My wort chiller hose melted to my brewpot, which was easily fixed
-The ending gravity came in at 1.056, much lower than expected with the additions I made
-My brewpal software somehow didn’t save my full notes (I found that out as I started this post)…which were pretty detailed. I’m happy I decided to write about my brew day while everything was fresh in my mind.

As I type this, the airlocks are going crazy, meaning fermentation has been started. I am contemplating letting the fermenters sit for as long as 4 weeks since most of my research has led me to think that the aging may help the flavor profile. In addition, I am thinking of adding some ‘Creme de Cacao’ into the secondary to give a stronger chocolate aroma and add a bit of alcohol since I anticipate this batch coming a bit low.
