Matt, and Maple-Bourbon Adam

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).

My new water filter, right into the mash tun!Hair of the Dog occasionally brews a version of Adam called Matt which augments the base with candi sugar, more malts, and bourbon and apple eau de vie barrel aging. Apple brandy and dark candi syrup seemed like a nice match, so I went with that for five gallons of the beer.

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 (through my new Camco filter), 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!

Sacch - 60 min @ 153F

Brewed 3/8/15

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.

3/19/15 Candi half down to 1.030 (70% AA, 9.5% ABV), the maple at 1.025 (77% AA, 11.5% ABV). Right where they should be, and fermentation appears finished.

3/22/15 Fermentation appears finished on both, moved to 55F ambient to settle.

4/5/15 Bottled the Matt portion. 5.25 gallons. Added 4 oz of Daron Calvados. Rehydrated 2 g of Pasteur Champagne yeast, and primed with 106 g of table sugar. Aiming for 2.3 volumes of CO2.

4/12/15 Kegged the Maple half with 1 cup of Medley Brothers bourbon.

2/2/16 Tasting notes for Maple-Bourbon Adam. Maple wasn't as assertive as I'd hoped, but it is there and melds nicely with the smoke, bourbon, and intense maltiness.

12/6/16 Tasting notes on the Cavados/Candi half.

12/29/16 Boiled 2 oz of toasted (55 minutes at 350F) maple bark chiseled off a tree in my parents' front yard in 2 qrts of water for 60 minutes uncovered. Infused 1 qrt of the resulting liquid into the keg. Really boosted the maple flavor! Boiled the remaining 3/4 cup of liquid with 1.5 cups of sugar until it reached 219F (for pancakes).

3/12/18 Tasting notes on the portion with maple bark.

Meadowfoam Honey Oatmeal Stout

One of the more fascinating talks I attended during National Homebrewers Conference 2014 in Grand Rapids wasn’t even about beer. Ken Schramm (author of the excellent Compleat Meadmaker, and founder of Schramm's Mead) talked passionately about bees, amino acids, and agriculture during "Really Understanding Honey." While he talked he passed around ten varietal honeys for us to taste with single-use straws. The range from a mild honey like blackberry to some of the weirder ones (e.g., leatherwood) was interesting. Others demonstrated how different a single varietal (like orange blossom) can be depending on what part of the world the bees collect nectar (milder California versus the more  more acidic/juicy Florida).

The two that really stood out to me were meadowfoam (toasted marshmallows) and Mexican coffee blossom (hint of coffee-like roast). I knew I had to get my hands on one or both of these to add to a stout! Last month I finally got around to brewing with meadowfoam honey. The base beer was a relatively straight-forward oatmeal stout, with 10% home-toasted oats rather than a breadier base malt. If I really wanted to play-to s’mores, I could have added a bit of smoked malt, but I didn’t want the flavor of the honey to be lost.

As with other honey beers I've brewed, I added the concentrated nectar when primary fermentation was nearing completion (four days after pitching). This prevents destruction of the volatile aromatics by the heat of the boil, and scrubbing by the vigorous primary fermentation. For the first time I also saved a few ounces of honey to add directly to the keg for natural conditioning. I'm usually not an advocate for using priming sugar to add flavor, but the pressure should trap the volatiles, and I can a easily adjust the carbonation with CO2 once it goes on tap.

2/13/15 Made a 3.5 L starter with 1 vial of month old yeast. Crash chilled after 24 hours on the stir-plate.

2/16/15 Brewed with some guy

Oats toasted at 340F 25 min. until they smelled toasty (only minimal color pickup).

Measured 5.3 mash pH.

3 gallon cold sparge. Collected 13 gallons of 1.045 runnings. Adjusted hops down by 1% AA.

Chilled to 65F, shook to aerate, pitched 2 L of the starter. 24 hours at 65F ambient, then to 58F ambient.

2/19/15 Back to 65F ambient to finish.

2/20/15 12 oz of Winter Park meadowfoam honey and 1/2 gallon of water to my half.

3/8/15 Racked my half (FG 1.020) into a keg with about 3 oz of meadowfoam honey. Purged and sealed. Left in the mid-60s to condition. Extra beer went into a growler with a small amount of the honey.

7/15/15 Tasting notes. Happy with the overall character of the beer, but the flavor of the meadowfoam honey itself barely comes through. I'd up it next time or find a more characterful supplier.

Shortcut Sour Tasting - Blackberry Oud Zwart

I realize my standard sour beer process can be daunting for some homebrewers. All grain, year-plus fermentation, fresh fruit, blending, bottle conditioning etc. Apparently not everyone has a temperature controlled basement room to commit to aging sours. So why not cheat? Brew a beer with malt extract that I could age just a few months with frozen fruit before force carbonating? So I did!

This extract-based stout was fermented with Wyeast’s Oud Bruin Blend. The blend doesn’t contain Brett, so it is perfect for a sour that derives character from malt and fruit. The combination of Lacto and brewer’s yeast won’t dry a beer out as much as my long-aged massively-mixed fermentations (1.012 in this case), perfect for a sour with some roast. Sour stouts have the highest probability of missing for my palate, roast+dry+sour often ends up acrid for me. WY3209-PC has only been released once so far, summer 2014.

I racked onto the frozen blackberries (and a handful of home-grown/frozen beach plums) one month into fermentation. A month later I moved the fermentor to my cool basement to prevent the sugars from the fruit from being completely fermented out (or so I hoped) – I liked the way the beer tasted and didn’t want it to change. I was kegging, so residual sugar was not a concern as it would have been if I was bottle conditioning.

Braam Oud Zwart

Appearance – Chocolate brown with substantial cloudiness. Not far off from a dunkelweizen; more brown porter than stout (despite the predicted 30 SRM). The tan head is dense and long lasting, particularly for a sour beer.

Smell – Brown malt, Cocoa Puffs, and winey fruit. Like nectarines, blackberries aren’t as distinct as many of the more popular sour beer fruits. As with the color, the dark malts don’t quite provide the punch I was hoping for, but it is coffee-roastier than traditional oud bruins. No funk, or other unexpected aromas considering it is only Sacch and Lacto.

Taste – Nice melding of bready malt and dried blackberry (toast and jam anyone?). It has a pleasant lactic tartness without being sharp. Very clean, no funk to get between the malt and fruit. Not sweet, but not dried out the way most sour beers are. The combination works well, but isn’t bursting with complexity.

Mouthfeel – Medium body, with medium carbonation. About right for the flavors. I never want prickly or thin when it comes to darker beers, sour or otherwise.

Drinkability & Notes – Nothing about this says “malt extract.” Although my lack of experience with extract beers certainly played a role in the lower dark malt character than I intended. Luckily falling short on a sour stout, I ended up at a pleasant destination. Hopefully Wyeast brings back this blend eventually, I think it’s a great place to start for a quick turnaround tart without the funk beer.

Palace of the Cracked Heads Tasting

One of my favorite fruits to add to sour beers is nectarine. They don’t dominate a subtle beer the way sour cherries or raspberries usually do. I’ve added them to a couple of pale sours, with beautiful results. When Jacob suggested them as one of the fruit choices for Empty Hats (Modern Times’ oud bruin) I wasn’t sure how it would work out. Nectarine is delicate for such a malty barrel-forward beer. Luckily the results are wholly different, but no less delicious!

There are some brewers who deem only their “best” sour beer suitable for fruit (given the increased price and manpower requirements). Others seem to be adding fruit to their worst beer in an attempt to cover-up wretched off-flavors. For me, the ideal barrels for fruit are those that are bland (i.e., those that lack bold and beautiful aromatics and/or adequate acidity). Dumping is the only real option for sour beers with strong off-flavors, no amount of fruit will cover them completely.

Modern Times Palace of the Cracked Heads

Appearance – Red headed towards amber. Hazier than the unfruited beer, but nowhere near murky or muddy. The head sizzles down within a minute, not leaving so much as a spec of foam.

Smell – Apricot fruit leather. Saturated stone fruit, but not so much that it dominates the beer-y nature of the beverage. Cherry-funk around the edges. At around one pound of nectarines per gallon, the rate lower than what I’ve used at home. Less fruit, combined with the more assertive base certainly changes the perception of the fruit, creating a more balanced profile (at the cost of the knock-your-socks-off farmstand aroma).

Taste – Big acidity, lactic and malic: bright, sharp, and quick. The nectarines are there, jammy, concentrated, but not juicy-fresh. I think the flavor melds better with the biscuity maltiness that the Vienna and Munich provided. The damp-barrel goodness is there, but the fruit covers up much of it. There is just a touch of acetic towards the back.

Mouthfeel – Solid carbonation, it is lively without being disruptive. The mouthfeel is a little stickier than the base beer, full enough to support the big flavors.

Drinkability & Notes – Rocking beer. Nice blend of fruit, malt, acid, and funk. It’s the early leader in the clubhouse for my favorite of the five “first round” Modern Times sour beers. There are still a couple more to go though!
