Turtle Toe Porter

As the weather swings cooler, my tastes swing to darker beers–porters, stouts, and such. So, I found a clone recipe for Deschutes Black Butte Porter on the AHA website and made a few modifications for yeast (American ale instead of English ale) and hops (to use up on-hand varieties).

The name comes from a fossil specimen in the museum lab at the moment–it’s a ~67 million year old turtle from Wyoming, which unexpectedly had complete hands and feet. “Turtle Toe Porter” is a very alliterative title for a beer, so the name stuck!

Turtle Toe Porter

  • 9.5 lb. California Select 2-row malt (Great Western)
  • 14 oz. chocolate wheat malt (Weyermann)
  • 10 oz. 80L crystal malt (Warminster)
  • 4 oz. carapils malt (Briess)
  • 0.75 oz. Magnum hop pellets (10.1% alpha), 90 minute boil
  • 1 oz. Cascade whole hops (5.5% alpha), 10 minute boil
  • 0.5 oz. Mt. Hood hop pellets (8.0% alpha), 5 minute boil
  • 1 Whirlfloc tablet, 5 minute boil
  • 1 pkg. US-05 American ale yeast (DCL/Fermentis)

Target Parameters

  • 1.050 s.g., 1.011 f.g., 5.2% abv, 39 IBU, 30 SRM
  • Full volume mash at 152° for 60 minutes, with 10 minute mash-out at 168°
  • Claremont tap water, treated with Campden tablet

Procedure

  • I mashed in with 7.5 gallons of water heated to 157°, to hit a target mash temperature of 152°. I added 5 mL of 88% lactic acid to bring down the mash pH. I recirculated the mash at this temperature for 60 minutes, before raising the mash to 168°. Then, I removed the grains and brought the runnings to a boil.
  • In total, I collected 6.4 gallons of runnings with a gravity of 1.044, for 69% mash efficiency.
  • I brought the kettle to a boil, adding hops and finings per the recipe. After a 90 minute boil, I turned off the heat and chilled to ~80°, before transferring to the fermenter. I chilled the wort the rest of the way in the fermentation chamber, before pitching the yeast.
  • I brewed this beer on 11 September 2021. Starting gravity was 1.051, and I fermented it at 66°.
  • On 18 September 2021, I pulled the beer out to ambient, around 70° to 72°, to finish out fermentation.
  • I kegged the beer on 24 September 2021. Final gravity was 1.014, which works out to 4.9% abv.

Tasting

  • Appearance
    • Brilliantly clear, deep brown beer with garnet highlights, that pours with a decently persistent tan head.
  • Aroma
    • Roasty aroma of coffee and chocolate at the front. No significant hop or yeast character evident.
  • Flavor
    • Roasty and cocoa notes dominate, with a touch of dark caramel behind that. The base malt profile has a slightly grainy character. Bitterness is moderate and fairly clean, with perhaps a slight woody character.
  • Mouthfeel
    • Medium body, moderate carbonation, dry finish.
  • Would I brew this again?
    • Yes! This is exactly the American porter that I wanted. It is flavorful, yet very drinkable. I like the roasted character in it, and it is a good beer to bridge the summer to fall transition. If brewed as a winter beer, I might add a bit more character by using Maris Otter, but that’s a fairly mild critique in the scheme of things.

    • 10/10

Polacanthus Porter

IMG_20190829_193848Dark beers! They’re seemingly banished from the summer months, and yet I often have a craving for one even on the hottest days. Not a triple imperial barrel aged chocolate stout, of course–that’s best dumped in the sink during the month of December. I’m thinking of those more drinkable dark beers, a bit lower on the alcohol but still robust on flavor.

An end-of-summer porter seemed like a good way forward. They’re flavorful, but not necessarily gut bombs. They’re relatively easy to brew, and turn around fairly quickly. Also, they’re a “traditional” style that’s just a bit harder to find, overwhelmed by trendier beers on tap lists. If I want a mediocre hazy IPA, I don’t need to make my own; there is no shortage in area breweries!

This recipe is based on the American porter from Gordon Strong’s Modern Homebrew Recipes. My version fairly closely follows that by Strong, with the modifications primarily on the hopping and malt brands. The name recognizes the combination of American and English ingredients, because Polacanthus is a type of armored dinosaur that had relatives on both sides of the Atlantic.

Polacanthus Porter

  • 11 lb. 2-row pale malt (Rahr)
  • 12 oz. 1823 Heritage Crystal Malt (Bairds), 75°
  • 10 oz. chocolate malt (Bairds), 500°
  • 5 oz. roasted barley (Bairds), 600°
  • 0.65 oz. Magnum hop pellets (13.2% alpha), 60 minute boil
  • 1 Whirlfloc tablet, 10 minute boil
  • 1 oz. Cascade whole hops (~5.5% alpha), 10 minute boil
  • 1 oz. Cascade whole hops (~5.5% alpha), 5 minute boil
  • 1 pkg. Safale American Ale Yeast (US-05)

Target Parameters

  • 1.058 o.g., 1.014 f.g., 5.8% abv, 36 IBU, 34 SRM
  • 60 minute infusion mash, 154°, batch sparge
  • Claremont tap water

Procedure

  • I mashed in with 4.25 gallons of water at 164.5°, to his a mash temperature of 155°. After 45 minutes, I added 1 gallon of water at 185°, and collected first runnings after a 10 minute rest and vorlauf. I then added 3.5 gallons of water, let rest for 10 minutes, vorlaufed, and collected second runnings.
  • In total, I collected 7.1 gallons of runnings with a gravity of 1.048, for 73% efficiency.
  • I brought the runnings to a boil, adding hops and such per the recipe.
  • After 60 minutes, I turned off the flame, chilled, and transferred to the fermenter (with aeration). I had to let the wort rest in the fermenter for a few hours, to chill down to the fermentation temperature of 66°.
  • I brewed this beer on 13 July 2019. Starting gravity was 1.057.
  • I kegged the beer on 14 August 2019. Final gravity was 1.013, for 5.8% abv. This was exactly on the dot for my targets!

Tasting

  • Appearance
    • Deep brown, with garnet tones when illuminated from behind; clear; persistent tan head
  • Aroma
    • Roasty, chocolately aroma; very nice.
  • Flavor
    • Roast malt character at the front, with a slight chocolate and coffee tinge; slight citrus aspect; moderately bitter, with a finish that tilts towards the bitter rather than the malty side.
  • Mouthfeel
    • Medium body, medium carbonation; off-dry finish (probably due to the roast character). It could maybe have a touch more body, but I think overall it’s okay on this end. Too much body would make this harder to drink.
  • Would I brew this again?
    • Yes! This is a nice and simple recipe, with a pleasant flavor. As porters go, this definitely is towards the roasted and bitter side, but I’m okay with that. This is really drinkable as a summer porter! I would add it to my regular repertoire.

    • 9/10
