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.

  1. It is best to have a trained professional blow the gunite into your basement because if the wet to dry mix ratio isn't correct or if the gunite isn't blown in correctly (and evenly) you can have some structural problems. Basement Renovations With clay in particular, it is important to make sure you have the ground compacted properly so you do not end up with the ground shifting under the weight of your home.

Brewing with The Grainfather, Part 1 - Mashing and Sparging

(Important note:  This article series is based on the US version of the product.  Prices are expressed in US dollars, measurements of temperature and volume are in US units unless otherwise noted.)

iMake's The Grainfather is an all-in-one RIMS brewing system designed to be used indoors with household electric current.  It includes the kettle, grain basket, recirculation tube, pump, electronic temperature controller, instruction book, and counterflow chiller.  It does not include a mash paddle, fermenter, cleaning supplies, or pretty much anything else.  The price is around $800-900 depending on where you shop and the discounts offered.

The Grainfather handles mashing, boiling, recirculating, sparging (to a degree), and chilling of the wort.  You'll still need a fermentation vessel of some sort and some other supplies we'll discuss later.

Grainfather Assembly and Initial Cleaning

Assembly of The Grainfather in my experience was pretty easy overall.  There were a couple of s…

Things I've Learned Brewing with The Grainfather, Part 2

In the last post, I shared an overview of The Grainfather, recommended equipment to use with it, and an overview of the brewing process.  In this installment, I'm going to talk specifically about mashing and sparging. Having brewed over a dozen batches with it, I'm finally becoming very comfortable with the device, the mash process, and how to get what I want out of it. I don't consider myself a "master" of it yet, though.

For those who have never done all-grain brewing, I want to provide a quick overview of the mash process itself.

Mashing - With or Without The Grainfather
The goal of mashing is to turn the starches in the grain into sugars. More specifically, you want to turn the starches into a mix of fermentable and unfermentable sugars that provide the flavor profile associated with the beer you are brewing. A sweeter beer might warrant more unfermentable sugars. A more dry beer will demand few unfermentable sugars.

To a great extent, controlling the amount o…

Brewing with The Grainfather, Part 3 - Cleaning and Overall Thoughts

In Part 1 of this series, I introduced The Grainfather and discussed how to use it for mashing and sparging.  In Part 2, we talked about boiling and chilling the wort with The Grainfather and its included counterflow chiller.  In this final segment, we'll discuss cleanup and overall thoughts about the device and its usage.

Cleanup

Once you've pumped the wort from The Grainfather into your fermenter and pitched your yeast, you're well on your way to a delicious batch of homebrew.  Unfortunately, you've still got some cleanup work to do.

The cleanup process in my experience will take 20-30 minutes.  It involves the following tasks:

Removing and discarding the grain from The Grainfather's grain basketCleaning the grain basket, kettle, recirculation tube, and wort chillerCleaning all the other implements used in brewing (scale, scoops, mash paddle, etc.) At the end of the brewing process, there will be hops bags (if you used them), grain and other residue, and usually so…
