Bear Butte Porter

Posted on by

Porters are a classic homebrewing style, and they are an accessible entry point for newer brewers because their rich flavors are simultaneously enjoyable and also able to cover the results of overheated fermentations. As my brewing has progressed, and my fermentation temperature control has improved, I come back to them again and again as an enjoyable winter beer.

Last year I made a Sierra Nevada Porter clone, and this year I delved into a clone recipe for Deschute Brewing’s Black Butte Porter. The version I had was pulled from the Brew Your Own Big Book of Homebrewing (2022 updated edition), with some small modifications for hops and yeast on-hand on-hand as well as some very slight malt quantity adjustments. Instead of Galena as the bittering charge, I subbed in Chinook, which seemed like a reasonable swap, and I used Mangrove Jacki’s M36 Liberty Bell ale yeast instead of Lalbrew’s Verdant strain. Again, this seemed to be a reasonable swap that would get me into the same flavor zone. Interestingly, I learned via David Taylor’s Yeast Master List that M36 is a blend of M42 (New World/Nottingham) and M15 (Empire/Windsor); the reported fruitiness of the strain seemed like a good fit for this particular batch.

It’s interesting to note that the BYO clone recipe is very different from an AHA clone recipe. The AHA version uses chocolate wheat malt instead of chocolate malt, 80L crystal instead of 60L crystal, and a bit of dextrine malt, and it also calls for WLP002. Hops include Hallertauer instead of Tettnang. I’m not sure which version is more “authentic,” and I suppose it doesn’t really matter in the end! As another aside, I brewed a version of the AHA recipe back in 2021, as Turtle Toe Porter.

Because this is not a direct version of the clone recipe, and in honor of a landmark in my home state, I have called this batch “Bear Butte Porter.” I also used some South Dakota-grown hops from my dad, another fitting addition to the beer.

Bear Butte Porter

  • 10.25 lb. 2-row brewer’s malt (Great Western)
  • 0.75 lb. crystal 60L (Briess)
  • 0.75 lb. chocolate malt (Simpsons)
  • 0.35 oz. Chinook hop pellets (12.3% alpha), 60 minute boil
  • 2 oz. Cascade whole hops (3.5% est. alpha), 20 minute boil
  • 1 Whirlfloc tablet, 5 minute boil
  • 2 oz. Tettnang hop pellets (2.4% alpha), 5 minute boil
  • 1 pkg. Liberty Bell ale yeast (Mangrove Jack’s M36)

Target Parameters

  • 1.052 s.g., 1.012 f.g., 5.4% abv, 33 IBU, 33 SRM
  • Full volume infusion mash, held at 152° for 60 minutes and 168° for 10 minutes
  • Claremont tap water with Campden tablet, with approximate ppm of 110 Cl, 50 SO4, 40 Ca, 156 HCO3, 12 Mg, 87 Na

Procedure

  • I heated 7.5 gallons of Claremont tap water, with Campden tablet, to 158°, before adding the grains as well as 6 mL of 88% lactic acid to adjust the mash pH. I held the mash at 152° for 60 minutes, with recirculation, before raising the temperature to 168°. After 10 minutes at the mash-out temperature, I removed the grains and heated the runnings to a boil.
  • In total, I collected 6.7 gallons of runnings with a gravity of 1.043, for 68% mash efficiency.
  • Once the runnings were boiling, I added the hops and finings per the recipe. After 60 minutes on the boil, I turned off the heat and chilled to 78° before transferring to the fermenter and dropping to 66° in the fermentation chamber.
  • Once the beer was at 66°, I pitched the yeast.
  • I brewed this beer on 25 October 2024; it had a starting gravity of 1.057.
  • I fermented the beer at 66° until 28 October 2024, when I pulled it to ambient (~70°). Active fermentation seemed mostly done, so I figured it wouldn’t hurt it to sit at ambient for awhile.
  • I kegged the beer on 16 November 2024. Final gravity was 1.016, for 5.4% abv. This was around 71% measured attenuation. It’s on the lower end that Mangrove Jack’s reports for the strain (74% to 78%), but in my experience I’ve often had lower attenuation with the Windsor strain that comprises part of this blend.

Tasting

  • Appearance
    • Deep, deep brown beer with dark garnet highlights, very clear. Pours with a persistent and creamy tan head. Beautiful! Great lacing down the side of the glass.
  • Aroma
    • Moderate dark chocolate: coffee aroma, a touch of earthy hop character.
  • Flavor
    • Slightly roasty and bitter chocolate malt character, a bit of dark sugar character; medium bitterness. A medium bit of dark dried fruit yeast character, but it’s in the background.
  • Mouthfeel
    • Medium carbonation, medium-full body, off-dry finish.
  • Would I Brew This Again?
    • I love this beer! It’s a perfect American porter, and wonderfully drinkable. Porter is such an underappreciated style; this version looks great and tastes great!

Sierra Nevada Porter Clone

Posted on by

I love American porters, and they are among the first beers I ever brewed (all the way back to 2009!). Sierra Nevada’s porter is a great one, a classic in the American porter style, as listed by the BJCP 2021 style guide. The BJCP also indicates that this style is “becoming increasingly hard to find.” That’s a good reason to make a homebrew version!

I did some searching to find an appropriate recipe, which landed on one that is allegedly directly from Sierra Nevada. I adjusted the grains very slightly to get more even amounts, and I also upped the Carafa Special III and black malt, in order to darken the beer. Oddly, the grain-only version was lighter than consistent with the style (noted by folks at the original link), so I added Sinamar to bring things into line. The original recipe called for Sterling and Aurora hops, neither of which I had on-hand. So, I substituted Mandarina Bavaria and Elixir. They’re not the same, but should be enough in the ballpark.

This was an enjoyable recipe to brew. It didn’t require dry hopping or whirlpooling, and I didn’t bother with a closed transfer. Other than using Sinamar, the ingredients and techniques were dead-basic.

Sierra Nevada Porter Clone

  • 10.25 lb. 2-row malt (Briess)
  • 1 lb. Munich I malt (Weyermann)
  • 0.5 lb. caramel malt – 60L (Briess)
  • 0.5 lb. chocolate malt (Bairds)
  • 1 oz. black malt (Briess)
  • 1 oz. Carafa Special III (Weyermann)
  • 1.5 oz. Sinamar (added at end of boil)
  • 1 oz. Mandarina Bavaria hop pellets (6.7% alpha), 60 minute boil
  • 1 oz. Elixir hop pellets (5.1% alpha), 15 minute boil
  • 1 Whirlfloc tablet, 5 minute boil
  • 1 oz. Elixir hop pellets (5.1% alpha), 5 minute boil
  • 1 pkg. California ale yeast, dry version (White Labs WLP001)

Target Parameters

  • 1.056 s.g., 1.014 f.g., 5.7% abv, 35 IBU, 40 SRM
  • Full volume infusion mash, held at 154° for 60 minutes and 168° for 10 minutes
  • Claremont tap water with Campden tablet

Procedure

  • I heated 7.5 gallons of water to 160°, and added the grains for a mash temperature of 154°. I added 5 mL of 88% lactic acid to adjust the pH, and held the mash at 154° for 60 minutes.
  • After 60 minutes, I raised the mash to 168° for 10 minutes, before pulling the grains and heating to a boil.
  • The mash yielded 6.5 gallons of runnings with a gravity of 1.050, for 71% mash efficiency.
  • I boiled the wort for 60 minutes, adding finings and hops per the recipe.
  • After the boil, I chilled to 70° and transferred to the fermentater.
  • I brewed the beer on 2 December 2023. Starting gravity was 1.058, just a touch above target.
  • I fermented the beer at 66°, and kegged on 31 December 2023. Final gravity was 1.016, for 5.5% abv.

Tasting

  • Appearance
    • The beer is a deep, deep brown, almost black, with a persistent tan head.
  • Aroma
    • Dark chocolate and coffee–very roasty! Resiny hop character. Very nice!
  • Flavor
    • Rich, chocolate and coffee malt notes. Medium-high bitterness with a resiny and piney character.
  • Mouthfeel
    • Medium body, moderate carbonation, slightly dry finish.
  • Would I Brew This Again?
    • Yes! This is a fantastic American porter, simultaneously rich and drinkable. It has interesting character, and is just a nice beer. I don’t know how it would stack up against Sierra Nevada’s product, but even on its own this recipe is pretty nice.
  • Overall
    • 10/10

Update: Olde Persica Porter

Posted on by

My smoked porter has been in the primary fermenter for 13 days, coasting along at around 66°. So, I kegged it tonight. Final gravity was 1.016, down from 1.060, for 5.8% abv. The aroma and flavor are pretty darned delicious! The level of smokiness is just about perfect for my palate, too. Everything is carbonating and conditioning now at 40°.

Accretion Porter

Posted on by

My oatmeal stout is popular–and so it is just about all gone, thanks to the able efforts of many friends and family members. I do like to have a “dark beer” on tap at all times, though, so it’s time for another brew. I had thought about doing a “session porter,” but thought instead I’d use up a bunch of ingredients and go for something a little bigger instead. I haven’t done a robust porter in awhile, so that seemed like a good style to aim for.

In formulating this recipe, I had a two things in mind. Firstly, I wanted/needed to use up a bunch of ingredients. Secondly, I wanted a rich and complex brew. The intersection of these two sets brought in a ton of dark grains–pale chocolate malt, roasted barley, de-bittered black malt, and black patent malt, along with a healthy dose of honey malt and dark crystal malt to bring some rich caramel characteristics. I was okay with having a high percentage of ultra-dark grains, because I felt the beer would need some of that to balance out any sweetness from the honey and crystal malts. I elected to use WLP002 (English Ale yeast), because I had a culture of that in the fridge. Plus, I figured that would add a nice complex and fruity dimension to the beer.

Thus, Accretion Porter was born! The name references the geological process by which some landmasses are formed–successive addition of a random smattering of crust–that mimics the assembly of the grain bill.

Accretion Porter

  • 9.5 lbs. Maris Otter (pale malt)
  • 1 lb. honey malt
  • 0.75 lb. crystal dark malt (77°L, Crisp)
  • 0.5 lb. flaked barley
  • 7 oz. pale chocolate malt
  • 4.4 oz. roasted barley
  • 4 oz. de-bittered black malt
  • 2 oz. black (patent) malt
  • 0.84 oz. Northern Brewer hops pellets (9.9% alpha), 60 minute boil
  • 1 oz. Cascade hops (whole; est. 4% alpha), 30 minute boil
  • 1 oz. Cascade hops (whole; est. 4% alpha), 10 minute boil
  • 1 tsp. Irish moss, 10 minute boil
  • 1 pkg. English ale yeast (White Labs WLP002), prepared in 1.5L starter.
Procedure
  • A day in advance, prepared a 1.5L starter of the yeast, which I had cultured previously. Because I don’t know when I’ll next get a chance to use this strain, I elected not to overbuild the starter.
  • I mashed in with 4.5 gallons of water at 168.5°, to hit a mash temperature of 155.5°. After 50 minutes, I added 0.75 gallons of water at 200°, let sit for 10 minutes, vorlaufed, and collected the first runnings. I added another 3.5 gallons of water at 180°, which raised the mash bed to 165.5°. I let this sit for 10 minutes, vorlaufed, and collected the remainder of the wort. In total, this was 6.9 gallons of wort with a gravity of 1.048, for 70% mash efficiency.
  • I brought the wort to a boil, and added the hops and Irish moss at the indicated schedule.
  • After 60 minutes, I turned off the heat and chilled the wort to 76°.
  • 5.1 gallons of wort went into the fermenter, with a starting gravity of 1.058. I am starting fermentation at ambient temperature (65°), and will move it into the fermentation chamber within 24 hours, for a fermentation temperature of 66°.
  • I brewed the beer on 19 March 2016.
