It’s been more than two years since my series of four barrel-aged strong/dark beers (Wheat Trippelbock, Rye Stout, Vanilla/Cinnamon Porter, and Quadrupel), and stocks are beginning to dwindle. It seemed like a good excuse to brew a variant on the fantastic Hair of the Dog Adam clone I brewed six years ago, considering I'm down to my final bottle (recently drank the second to last – still tasted fantastic). However I didn’t want 10 gallons of the same ~10% ABV beer (no matter how well it ages).
I’d been thinking of brewing a Baltic porter inspired by the transcendent Les Trois Mousquetaires Porter Baltique I brought back from Montreal… with the addition of maple syrup and bourbon. I decided it would be a bit too close to Adam (both are dark, lightly smoky, and 10% ABV) so I transferred the concept to Adam. Maple syrup plus some bourbon is a technique that I’ve use to great effect before in a Founder's Canadian Breakfast Stout inspired RIS variant. I wanted more maple flavor so I added one quart (nearly three pounds) of grade B maple syrup after primary fermentation slowed. That may sound like a crazy amount in five gallons, but I've heard that some highly sought-after maple beers are brewed with twice that rate (around 10% maple syrup by volume!).
The base recipe is pretty close to my first Adam clone. I tweaked a few percentages and hops, but the only major substitution was the switch from intense peat-smoked malt to a mellower combination of Briess Cherry Wood Smoked and Weyermann Beech Smoked. I used a higher percentage of smoked malt than the first batch, so hopefully the smoke intensity will be similar, if a bit sweeter.
This was the first strong beer (over 1.075) I brewed on the new system. I used the technique borrowed from HoTD, collecting only my target volume of first runnings and boiling down well below the target volume. This concentrates the sugars and amino acids, increasing the rate of Maillard reactions (raising the pH slightly with baking soda further encourages this process). Rather than top-off with water, I sparged with cold water to collect four gallons of second runnings which I boiled for 45 minutes separately. This resulted in pretty good efficiency (overshooting my target gravity) so I topped-off with water post-boil. Nice to have 8 gallon fermentors to accommodate situations like this!

Added 4 g of CaCl to the mash and 3 g of baking soda to the boil. Collected 11 gallons of 1.078 runnings in the main kettle, plus 3.5 gallons of 1.060 in a separate kettle.
IBUs likely lower than projected given concentrated wort. Boiled down to about 6 gallons (~1.143). Added the 3 gallons of second runnings, plus 1 gallon of water to get to 10.5 gallons at 1.105 in the kettle. Then mixed with the entire yeast cake from the Honey Stout which was resuspended in another gallon of water for 11 gallons in the fermentors (poured back and forth to mix). Wort temperature was 64F in the fermentor. Left at 56F ambient.
Added 45 seconds pure oxygen about five hours after pitching.
Good fermentation by 24 hours. Temperature is a bit cool for this strain, so I wrapped the fermentors in a blanket to help hold in the heat of fermentation.
3/11/15 Moved to 67F ambient.
3/12/15 Still fermenting, thankfully as it's at 1.060 (37% AA), only half way there...
3/15/15 Still slowly ticking along, 1.038 (60% AA). Krausen has only gotten bigger. Adding sugars tomorrow.
3/16/15 Still some krausen, but activity seems to have mostly stalled. Added 32 oz (by volume) ~2.8 lbs of Whole Foods Grade B maple syrup to the bucket (effective OG = 1.111), and 1 lb of D-90 Candi Syrup to the Speidel (effective OG = 1.101). Still at 67F ambient.
3/22/15 Fermentation appears finished on both, moved to 55F ambient to settle.
