Belgian Golden Strong Ale 1.0

There are few Belgian beer styles that I haven't tried to brew. The Golden Strong Ale is one of those. It's a fairly basic style in terms of the ingredients. It's pilsner malt, sugar, Styrian Goldings hops, and Czech Saaz hops. The yeast should deliver fruity esters but not too many spicy phenols.

According to the Wyeast web site, Wyeast 1762 is one of the recommended strains for Belgian Golden Strong Ales. Their web site says that it's a relatively clean fermenter that produces dried fruit esters when fermented at higher temperatures or in a high-gravity wort. Wyeast 1388 is their recommended choice for the style, but 1762 is also recommended. Since I happened to have 1762 on-hand, I used it.

Ingredients

6.75 pounds of Swaen Pilsner Malt
1.72 pounds of Corn Sugar (dissolved in starting water
3.5 gallons of starting water
1.1 ounces of Styrian Celeia hops @ 2.8% AA (60 min.)
1.1 ounces of Styrian Goldings hops @ 2.8% AA (7 min.)
1.1 ounces of Czech Saaz hops @ 3.0% AA (6 min.)
1/2 vial of White Labs Clarity Ferm
1 packet of Wyeast 1762 past its expiration, raised up in two 1 liter starters

According to the PicoBrew Recipe Crafter, this beer should have the following characteristics:

  • BJCP Style: 25.C Belgian Golden Strong Ale
  • Original Gravity: 1.087 SG (1.074 SG actual)
  • Final Gravity: 1.022 SG (1.010 SG actual - as of 11/1/2018)
  • IBU: 22
  • SRM: 4
  • ABV: 8.5% (8.3% actual - as of 11/1/2018)
  • Batch Size: 2.5 gallons

The mash schedule for this batch is a modified version of the PicoBrew High-Efficiency Mash Profile, intended to take care of beta glucans and maybe dial up ferulic acid for the yeast:

  • Dough In at 102F for 20 minutes
  • Mash at 120F for 15 minutes (beta glucan and ferulic acid)
  • Mash at 149F for 60 minutes
  • Mash at 152F for 30 minutes
  • Mash Out at 175F for 10 minutes
The boil schedule:
  • 90 minutes: No hops additions (although a 90-minute boil might not be needed to drive off the DMS that's common from pilsner malt, I figured it might help increase the original gravity and give the beer a chance to drop a little clearer)
  • 65 minutes: Styrian Goldings
  • 7 minutes: Styrian Goldings
  • 6 minutes: Czech Saaz
The planned fermentation schedule:
  • Chill to 65F after brewing
  • Free-rise from 65F to "as high as" 80F (the yeast's optimum is 65-75F)
  • When gravity reaches 1.025 SG or lower, raise temp to 75F and hold there until gravity stops dropping.
Bottling will be with 5 carbonation drops per bottle (high carbonation).

Post-Brew Notes and Observations

10/27/2018: The Zymatic glitched a bit during the mash, with the temperature rising to 150F and then suddenly dropping down to 149F before bouncing back up to the 149F it was supposed to be. Whatever happened seemed to self-correct before I got to it to check on it. 

When I went down to check on it during mash out, I found a surprise. It had apparently overflowed the step filter, the drip tray, and leaked around the two plastic bins I'd put under the drip tray to catch any overflow. One of those plastic bins had about an inch of wort in it. The other had none. There was wort across part of the table top, dripping onto the floor, running across the basement floor, under a trash can and shelving unit, and puddled near the drain. Apparently quite a lot of wort had leaked while I was away from the machine. It even looked like some wort might have been dripping out of the machine itself. I spent quite a while mopping that mess up.

Original gravity registered as 1.074 SG and the starting temperature was 74F. I drained most of the wort from a 1 liter starter, then swirled the rest and added it to the fermenter. I'm hoping there's enough live yeast to ferment the beer. We'll find out soon. If not, I have a fresh package I can use.

10/28/2018: The yeast appears to have grown in the starter (or been supplemented/replaced with wild yeast) as the gravity has been dropping steadily since about 3 hours after the yeast slurry was pitched. As of this writing, it's down to 1.052 SG from the initial 1.074 SG. That's roughly 30% attenuation and 2.9% ABV in under 24 hours.

10/29/2018: The gravity is now down to 1.033 SG and continues to decline. That's roughly 53% attenuation and 5.1% ABV in about 48 hours.

10/30/2018: The gravity is down to 1.016 SG. I raised the temp to 76F to get it to finish out fully.

10/31/2018:  The gravity has dropped to 1.012 SG today, and the temp is down to 73F. That's 82.2% attenuation and 7.9% ABV.

11/1/2018:  The gravity is down to 1.010 SG. That's 86.3% attenuation and 8.3% ABV. It looks like the gravity may finally be bottoming out.

11/3/2018: Gravity is down to 1.008 SG, which represents 89% attenuation and 8.5% ABV.

11/4/2018: Since I have it on-hand and have never used it, I decided to add Biofine Clear to this batch to see if it will drop nice and bright for me. I added a teaspoon to start, and may add more if needed later.

11/08/2018: I moved the fermenter into my mini-fridge to cold-crash and clear up.

11/14/2018: The fermenter was removed from the mini fridge and the beer bottled using five small carbonation tablets per bottle (high carbonation). The bottles were moved to my 76F hot box to carbonate

British Old Ale 1.0

The finished beer
One of my themes in 2018 has been to brew some new styles of beer. My approach is to read the available information in the BJCP guidelines, online forums, magazines, and anywhere else I can find it. I'll study the recipes to look for common themes and ratios, try to imagine how those recipes might taste as finished beers, and then come up with my own recipe based on what I've read.

The British Old Ale style is one that I've liked when I've found a rare example here in the USA. Since I have never brewed one, today seemed to be the right time to try.

My goal here is to create a darker-colored, higher-gravity Old Ale that's balanced (between malt and hops) and complex enough to make you want to sip it thoughtfully.

Ingredients

8.25 pounds of a mix of Belgian Pale Ale and Swaen Pale Malt (see note below)
2 ounces of British Medium Crystal Malt (50-60L)
2 ounces of Belgian Special B Malt
1 ounce of Carafa III Special Malt
8 ounces of Lyle's Black Treacle (added to starting water)
1 ounce of Fuggles hops @ 4.5% AA (60 min.)
1 ounce of Fuggles hops @ 4.5% AA (45 min.)
1 ounce of Fuggles hops @ 4.5% AA (5 min.)
1/2 tsp. Gypsum in the mash
1.5 tsp. pH 5.2 Stabilizer in the mash
1/4 tsp. Yeast Nutrient with the last Fuggles addition
1/2 tsp. Brewtan B with the last Fuggles addition
3.4 gallons of starting water (mixed with the treacle)
1/2 vial White Labs Clarity Ferm
1 packet Lallemand London ESB dry yeast

(Note: I wanted to use Maris Otter as the base, but I was out of it. The other malts needed to be used up, and were European malts - so they were as close as I could get. I used the Special B malt for the same reason - it was close to the British malt I wanted to use in its color, and should contribute a nice flavor to the finished beer. I used Carafa III as a replacement for Black Patent Malt to color the beer.)

According to the PicoBrew Recipe Crafter, this beer should have the following characteristics:
  • BJCP Style: 17.B Old Ale
  • Original Gravity: 1.092 SG (1.067 SG actual)
  • Final Gravity: 1.025 SG (1.014 SG actual)
  • IBUs: 45
  • SRM: 22.9
  • ABV: 8.9% (7.0% actual)
  • Batch Size: 2.5 gallons (1.9 gallons actual)
The mash schedule will be a modified version of the Zymatic High-Efficiency Mash:
  • Dough In at 102F for 20 minutes
  • Step 1 at 120F for 15 minutes
  • Step 2 at 152F for 60 minutes
  • Step 3 at 159F for 20 minutes
  • Mash Out at 175F for 10 minutes
The boil schedule:
  • 60 minutes: Fuggles addition
  • 45 minutes: Fuggles addition
  • 5 minutes: Fuggles, BrewTan and Yeast Nutrient additions
The wort will then be pumped through a counter-flow chiller into a fermenter and cooled further to a yeast-safe temperature before the yeast and Clarity Ferm are added.

The Lallemand ESB yeast likes to be between 65F and 72F. I'm planning to hold it at 68F until it's attenuated at least 60% of the sugar away, and then will raise it to 72F to finish out. I'm expecting this could take two weeks given the relatively high gravity of the brew.

I'll then bottle it with a low or medium carbonation level and allow it to age a bit before serving.

Post-Brew Notes and Observations

10/21/2018:  During the boil, the keg post between the Zymatic and the keg became clogged, slowing the flow of wort back into the keg during the boil and almost completely stopping it by the last three minutes of the boil. I came back to the machine to find the grain bed mostly full of wort. I drained the machine and pumped the wort into the fermenter, disappointed to find that there was less than two gallons and a very low gravity. I'll have to re-brew this beer to know how this recipe might really turn out. I'll pitch yeast into this one anyway and see what we end up with.

It's possible the back-up into the grain bed might have extracted tannins from the grain husks and given the beer a nasty tannin edge. It may have prevented the wort from flowing properly through the hop cages, resulting in over-bittering or under-bittering. Even if the bittering was right on target, the gravity of the beer came up 25 points low, so it could be way over-bittered for the original gravity. I won't really know until fermentation is over.

10/29/2018:  Gravity is down to 1.014 SG and is starting to level off. That's about 78% attenuation and 7% ABV.

10/31/2018: Gravity is currently holding at 1.014-1.015 SG and the temperature is holding at 66F.

11/3/2018: Gravity has been holding at 1.014 SG for a while now. That appears to be its final gravity. Time to bottle it and give it time to condition.

11/4/2018: The beer was bottled today, using three small carbonation tablets per bottle. Yield was only 21 bottles.

11/27/2018: The beer is about 3 weeks old now. When I opened the bottle, there was a solid hiss of released CO2 pressure. The beer poured a nearly opaque reddish brown with nice off-white head that lasted a while. The aroma hints at malt and licorice. The flavor is decidedly malty, with hints of prune or raisin, a clear but not too intense bitterness, a medium to full mouthfeel, and a bitter aftertaste. It's a good beer, but I wonder how much better it might have been if I'd hit my target gravities and had the ingredients on-hand that I'd wanted to use. I'll try the beer again in a few months to see how it has improved with age (if it has). I will also probably brew it again once I have the right ingredients.

2018 Dubbel 3.0

The finished beer
I've brewed plenty of Belgian-style Dubbels over the years, from a variety of recipe sources. None of them has ever really blown me away. If you've ever had a cellared bottle of Bornem's "Double" then you know what my ideal Belgian Dubbel is like. If I could brew something close to that, I'd be happy and have my "house" Dubbel recipe.

My goal is a deep ruby color with a lingering whipped-creamy head. The aroma should suggest noble hops, a touch of caramel, and dark fruit. The flavor should be slightly sweet, a pilsner malt backbone with hints of chocolate and plenty of prune, raisin, and plum flavors. It should finish clean with no lingering cloying sweetness and no lingering hop bitterness.

With these goals in mind, I've started from the ground up for this recipe. I'm using a base of Pilsner malt and Munich to provide some sweetness. To that, I'm adding Special B malt and Dark Candi Sugar rocks to provide the dark fruit flavors, Caramunich for some caramel, and Belgian Chocolate malt to darken it and add the chocolate notes. The Ardennes yeast strain will hopefully bring in some fruity and spicy notes. The Clarity Ferm is something I typically add to ensure that a friend of ours who is gluten-intolerant can enjoy the beers I brew.

Ingredients

4 pounds Belgian Pilsner Malt
2 pounds Munich I Malt
6 ounces Special B Malt
6 ounces Dark Candi Sugar rocks (dissolved in starting water)
4 ounces Caramunich Malt
1 ounce Belgian Chocolate Malt
1 ounce Styrian Celeia hops pellets @ 2.8% AA (60 min.)
0.51 ounces Czech Saaz hops pellets @ 3.0% AA (15 min.)
1/4 tsp. Yeast Nutrient
1/2 vial White Labs Clarity Ferm
1/4 tsp. Brewtan B in the boil (15 min.)
1 packet Wyeast Belgian Ardennes 3522 yeast
3 gallons plus 32 ounces starting water in the keg

According to the PicoBrew recipe crafter, the beer should have the following characteristics:
  • BJCP Style: 26.B Belgian Dubbel
  • Batch Size: 2.5 gallons
  • Original Gravity: 1.068 SG (1.071 SG actual)
  • Final Gravity: 1.018 SG
  • IBUs: 20
  • SRM: 29
  • ABV: 6.6%
The mash schedule will be:
  • Dough In at 102F for 20 minutes
  • Mash at 120F for 15 minutes
  • Mash at 159F for 60 minutes
  • Mash Out at 175F for 10 minutes
The boil schedule will be:
  • 90 minutes: No additions
  • 60 minutes: Styrian Celeia hops added
  • 15 minutes: Czech Saaz hops, yeast nutrient, and Brewtan B added
The wort will then be chilled to a yeast-safe temperature and the yeast pitched into it. The Ardennes yeast likes temperatures in the 65F to 76F range, but I've heard stories that it does well even up into the lower 80's. My plan is to let it free-rise and only to introduce cooling if the beer climbs into the 80F range.

Post-Brewing Notes and Observations

10/20/2018: The brew finished 3 SG points higher than anticipated. It came out of the chiller at 82F, which was a bit high for the yeast, so I left it to cool a while before I was comfortable pitching the yeast. The yeast packages were a bit old and didn't seem to be swelling anyway, so waiting a while would give the yeast a chance to "wake up" if it was going to. I set aside some dry yeast to use if the liquid yeast didn't make it. I plan to give the yeast at least 24 hours to become active before pitching an alternative yeast.

11/1/2018: I bloomed a half-teaspoon of gelatin in distilled water, heated it to the 155-160F range, and treated the beer before cold-crashing it.

11/4/2018: I bottled the beer today, using 5 carbonation tablets (high carbonation) per bottle. Yield was 22 bottles. The bottles were placed in a 76F "hot box" to bottle condition.

11/27/2018: This is one of the better Dubbels I've brewed, but it's still not precisely what I want. I suspect that if I'd had the right yeast (I wanted Wyeast 1762) that would have helped. A couple of ounces of Melanoidin malt would have changed the consistency of the foam to what I wanted and maybe added more redness to the color. But I am still not quite hitting the dark fruit notes I want from the beer. I may try adding raisins to the next version. I've had several American-made Dubbels that weren't as good as this one, but I'm sure I can do better.

It's got a good head, but it doesn't quite match what I wanted

Scofflaw Basement IPA Clone 1.0

At the BrewDog Annual General Mayhem (AGM) event in Columbus this year, I had the opportunity to meet the brewers from Scofflaw Brewing in Atlanta. I enjoyed all of their beers I tried, but one that stuck with me was their "Basement IPA", due to its sweetness and intense fruit flavors. The Scofflaw representatives said they brewed a sweet IPA because the market in Atlanta seemed to prefer it, as it was reminiscent of sweet tea. I reached out to ask if they'd share their recipe, but got no response.

I decided to take a shot at cloning it myself, just for fun. From their web site, I knew that it contained 2-row Pale Malt, Acidulated Malt, and Carafoam Malt. It is hopped with Chinook and Citra hops. It's a 7.5% ABV beer with a reported 40 IBUs. Given that the bitterness in Basement isn't particularly intense or harsh, I suspect it's late-hopped more like a New England IPA than a traditional West Coast IPA. For that reason, I'm not starting my hops additions until the last 30 minutes of the boil. This should provide a smoother bitterness and intensify the fruit flavors from the hops. I'll mash for 90 minutes, half at 152F for fermentability and half at 156F for some residual sweetness (hopefully). I doubt it will be a perfect clone, but will serve more as a starting point for trying to dial in a better recipe.

Ingredients

6 pounds Rahr 2-Row Malt (82.7%)
1 pound Carafoam Malt (13.8%)
4 ounces Acidulated Malt (3.5%)
0.20 ounces Chinook hops @ 12% AA (30 min.)
0.55 ounces Citra hops @ 13% AA (15 min.)
0.45 ounces Citra hops @ 13% AA (10 min.)
0.05 ounces Chinook hops @ 12% AA (10 min.)
1/8 tsp. Brewtan B in the mash water
1/4 tsp. Gypsum in the mash water
1/4 tsp. Brewtan B in the boil with the first Citra addition
1 packet Safale S-04 English Ale yeast
1/2 vial White Labs Clarity Ferm (for gluten reduction)
3 gallons filtered starting water plus 30 ounces *
(* If you brew this, I recommend reducing the starting water to 8 ounces more than the recipe crafter recommends. 3 gallons plus 30 ounces was way too much.)

(If you're wondering why the small amount of Chinook in the 10-minute addition, that's because I didn't want to open another ounce of Citra just to hit my planned 0.50 ounce final addition amount.)

The PicoBrew recipe crafter estimates the beer will have the following characteristics:
  • BJCP Style: 21.A American IPA
  • Original Gravity: 1.074 SG (1.069 SG actual)
  • Final Gravity: 1.015 SG (1.007 SG actual)
  • IBUs: 39
  • SRM: 5
  • Estimated ABV: 7.6% (8.2% actual)
  • Batch Size: 2.5 gallons (actual ended up less, see below)
Mash Schedule:
  • Dough In at 102F for 20 minutes
  • Rest at 120F for 15 minutes
  • Heat to 152F
  • Mash at 152F for 45 minutes
  • Mash at 156F for 45 minutes
  • Heat to 175F
  • Mash out at 175F for 10 minutes
A 75-minute boil is used,with this schedule:
  • 75 minutes: No additions
  • 30 minutes: Chinook
  • 15 minutes: Citra and Brewtan B
  • 10 minutes: Citra plus Chinook
The wort will be pumped through a counterflow chiller and then cooled to 66F before yeast is pitched.

I plan to let the beer free-ferment in a 68F basement, which is within the yeast's range.

I plan to bottle it with 4 small carbonation drops (medium carbonation) per bottle and hold it at 70F until the beer is carbonated.

Post-Brew Notes and Observations

10/05/2018:  It seems like there was too much water added again, as the mash compartment of the step filter was full to the lid. I'll need to reduce starting water next time around.

There was a fair amount of foaming near the end of Dough In and during the mash, but no spilling outside the drip tray.

As the Zymatic was heating the wort to boiling, it generated a Fatal Error #1 (heat loop inconsistency). After some diagnosis, I learned that the grain compartment overflow apparently clogged the duck valve and prevented the system from pulling wort out of the tray. I unclogged the valve and drained the tray, then removed the hops cages and cleaned the grain and remaining wort out of the tray. I then restarted the brew from the Mash Out step (although there was no grain in it). Next time I need to reduce the amount of starting water, perhaps to only 3-4 ounces more than the recipe software calculates.

Volume was probably low. I didn't measure it, but I'm estimating 2 gallons. Original Gravity came out at 1.069 SG instead of the expected 1.074. Yeast was pitched once the wort cooled to 75F, which was around midnight.

10/06/2018: This morning, I noticed the gravity had already dropped to about 1.060 SG and the temperature had only dropped to 73F, which is near the upper end of the yeast's optimum range. I moved the entire fermenter into my mini-fridge for 2-3 hours to cool it back down into the lower end of the yeast's range to avoid stressing it and introducing off flavors.

10/07/2018: The temperature climbed to 74F overnight, so I moved the fermenter back into the mini-fridge to cool down. I removed it when the beer was at 66F and the gravity had dropped to 1.012 SG, which is lower than the expected final gravity. That puts the current ABV at 7.5% and the apparent attenuation at over than 81%. By midnight, the gravity was still holding at 1.012 SG and the temperature was holding at 69F. A taste of the beer from the fermenter showed a mild sweetness and strong hoppy fruit notes which reminded me of the actual Scofflaw beer. It will be interesting to see how this one turns out.

10/08/2018: The temperature is now up to 70F. Gravity is reading 1.009 SG today, well below the estimated 1.015 final gravity.

10/09/2018: The temperature is holding at 70F. Gravity has bounced back and forth between 1.008 SG and 1.009 for the last day or two.

10/13/2018: I bloomed and heated a teaspoon of gelatin in distilled water, added it to the fermenter, and placed the fermenter in the mini-fridge to cold crash. I'll bottle in a week or so when it's cleared up a bit.

10/20/2018: The beer was bottled today, using four small carbonation drops per bottle (medium carbonation). Yield was 18 total bottles, owing to losses from the issues during brewing. Final gravity was reported as 1.007 SG by the Tilt Hydrometer.
