Eagle Face Oatmeal Stout 2021

Posted on by

I have made this recipe a million times (okay, more like seven or eight times), and it’s still just so enjoyable. Here’s the latest!

Eagle Face Oatmeal Stout 2021

  • 8.5 lb. Finest Maris Otter Ale Malt (Crisp)
  • 1.5 lb. flaked oats
  • 1 lb. 80° caramel malt (Briess)
  • 1 lb. Victory malt (Briess)
  • 0.5 lb. roasted barley (Briess)
  • 6 oz. chocolate malt (Briess)
  • 6 oz. chocolate malt (Dingemans)
  • 0.5 lb. rice hulls
  • 1 oz. Magnum hop pellets (10.1% alpha), 60 minute boil
  • 1 Whirlfloc tablet, 5 minute boil
  • 2 pkg. Nottingham ale yeast (Lallemand)

Parameters

  • 1.059 o.g., 1.017 f.g., 5.6% abv, 34 IBU, 35 SRM
  • Full volume mash, no sparge, 156° mash for 60 minutes, 10 minute mash-out at 168°
  • Claremont tap water, treated with Campden tablet

Procedure

  • I heated ~7.5 gallons to 164°, and then mashed in to hit a target mash rest of 156°. I added 5 mL of 88% lactic acid, to adjust pH.
  • I held the mash at 156° for 60 minutes, and then raised it to 168°. I held it at this temperature for 10 minutes, and then pulled the grains.
  • In total, I collected 6.4 gallons of runnings with a gravity of 1.048. This was a bit below my target (1.052).
  • I brought the runnings to a boil, and boiled for 15 minutes before adding the hops. I then proceeded with an additional 60 minutes on the boil, before turning off the heat and

Tasting

  • Appearance
    • A black, clear beer, with a somewhat persistent tan head. The beer is a very dark brown when viewed on edge.
  • Aroma
    • Earthy aroma, with coffee and chocolate and roasted malt. There is a faint dried dark stonefruit aroma.
  • Flavor
    • Medium-high bitterness, and a coffee/chocolate, exceptionally malty flavor. This is a wonderfully rich beer! The yeast character is pretty clean, with a very faint fruitiness. There is an earthy background, perhaps from the hops.
  • Mouthfeel
    • Very full bodied, with a somewhat slick mouthfeel as would be expected from an oatmeal stout. It is very smooth, with a slightly dry finish.
  • Would I Brew This Again?
    • It’s interesting that I pick up earthy characteristics in the aroma, given that there is only a single hop addition as a 60 minute bittering charge of Magnum. That must be produced by the malt combination, but I can’t figure out whre.
  • Overall
    • 10/10

Eagle Face Oatmeal Stout 1.5

Posted on by

Another year, another iteration of the Eagle Face! This is my absolute favorite recipe, and it has done well for me. I’m entering this in the national homebrew competition this year, after scoring a very respectable 40 last year. Unfortunately, the comments on the judging sheets were not as precise as I would like, other than a vague “needs more malt character.” So, I decided to change the background malt from 2-row to Maris Otter. Other than a minor change in bittering hops, this is pretty much exactly the same as I usually brew. Following last year’s example, I toasted the oats for a bit, too.

Eagle Face Oatmeal Stout 1.5

  • 7.5 lbs. Maris Otter pale malt
  • 1.5 lbs. flaked oats (toasted 1.25 hours at 300°)
  • 1 lb. 80° crystal malt
  • 1 lb. Victory malt
  • 0.75 lb. chocolate malt (Briess)
  • 0.5 lb. roasted barley (Bairds)
  • 6 oz. rice hulls
  • 0.53 oz. Magnum hop pellets (11.8% alpha), 60 minute boil
  • 0.31 oz. Warrior hop pellets (15.8% alpha), 60 minute boil
  • 1 Whirlfloc tablet, 10 minute boil
  • 1 pkg. English ale yeast (WLP001), prepared in 1L starter 24 hours in advance

Target Parameters

  • Infusion mash to hit target of 158°, 60 minutes, batch sparge.
  • 1.062 o.g., 1.023 f.g., 5.2% abv, 37 IBU, 41 SRM
  • Claremont tap water, 56 ppm Ca, 9 ppm Mg, 23 ppm Na, 41 ppm SO4, 21 ppm Cl, 220 ppm HCO3, 135 ppm RA

Procedure

  • I mashed in with 4.25 gallons of water at 171°, to hit a mash temperature of 158°.
  • After 60 minutes, the mash was down to 157°. I added 0.75 gallons of water at 180°, let rest 10 minutes, vorlaufed, and collected the first runnings. I then added 3.25 gallons of water at 180°, vorlaufed, and collected the second runnings.
  • In total, I collected 6.25 gallons of wort with a gravity of 1.053, for 74% efficiency.
  • I boiled for 60 minutes, adding hops and finings per the schedule in the recipe.
  • After a 60 minute boil, I cooled to 72°, pitched the yeast, and put the beer in the fermentation chamber. I’ll be fermenting at 68°.
  • I brewed this beer on 24 February 2018. Starting gravity was 1.062–right on target!
  • Update: I kegged this beer on 8 March 2018. Final gravity was 1.028, a bit higher than predicted, but I’m pretty comfortable that the beer is fully fermented out. Everything tastes pretty good right now; calculated abv is 4.5%.

Update: Good Riddance Pale Ale and Eagle Face Oatmeal Stout

Posted on by

Tonight it was time to keg my most recent pale ale and my annual oatmeal stout batch.

Good Riddance Pale Ale, after 20 days in the primary fermenter, was down to 1.011 from a starting gravity of 1.053. This equates to 5.6% abv. As I kegged the beer, I added a weighted mesh bag with the dry hops (1 oz. Amarillo hop pellets, 1 oz. Falconer’s Flight 7C’s hop pellets). I’ll be letting this sit at ~68° under carbonation pressure for at least a few days before serving.

Eagle Face Oatmeal Stout (1.4) had been in the primary fermenter for 15 days. It had a starting gravity of 1.060 and a final gravity of 1.019, equal to 5.4% abv. The gravity was a few points more attenuated than expected–most likely due to the slightly lower-than-normal mash temperature for this particular iteration.

This whole undertaking was a good reminder of why I am glad I was able to switch over to kegging–it took barely an hour to sanitize the kegs, keg the beers, clean my transfer equipment, and set the fermenters to soak! I would have needed up to twice that time for bottling!

Eagle Face Oatmeal Stout (1.4)

Posted on by

Time to do the semi-annual brew of my world-famous recipe (by virtue of appearing in Zymurgy), Eagle Face Oatmeal Stout! This iteration has only small modifications, to account for my current mash efficiency (~75%), which means a slight reduction in the amount of base malt. I also changed the hops (to use up one of my high-alpha hops), which shouldn’t result in a substantive difference for the flavor profile because they’re really just for bittering anyhow. Finally, I toasted my oatmeal to try something a little different. The day before brewing, I set the oats in a 350° oven for 1.25 hours, which resulted in a nice toasty aroma and crispier oats with a slight golden edge on most of the flakes. We’ll see how that changes stuff (if it does).

Toasted oats, ready for the brew.

Eagle Face Oatmeal Stout 1.4

  • 7.5 lbs. 2 row malt (Great Western)
  • 1.5 lbs. old-fashioned oats (lightly toasted)
  • 1 lb. 80° L crystal malt (Briess)
  • 1 lb. Victory malt (Briess)
  • 0.75 lb. chocolate malt (Briess)
  • 0.5 lb. roasted barley (Bairds)
  • 0.38 lb. rice hulls
  • 1 Whirlfloc tablet, 10 minute boil
  • 0.82 oz. Magnum hop pellets (13.2% alpha), 60 minute boil
  • 1 pkg. English Ale yeast (White Labs WLP002, in starter)

Target Parameters

  • 156° mash, 60 minutes
  • 1.061 o.g., 1.022 f.g., 5.1% abv, 37 IBU, 41 SRM, 5.5 gallons into the fermenter

Procedure

  • A few days in advance of the brew, I prepared a 2L starter. After two days on the stir plate, it was starting to flocculate out, and so I cold-crashed the starter. I split the starter into a 1.4L volume for pitching in this batch, and set aside 0.6L for a later brew.
  • As with my most recent brewing session, I have modified my mash procedure slightly. I added the strike water directly to the unheated mash tun, and then added the malt after temperature stabilized at my desired strike point. In this case, I added 4.2 gallons of water at 180°. Once in the mash tun, the temperature dropped to 175°, a bit above my target of 168.7°. So, I let things sit until it matched my target, and then mashed in. For future reference, I should only overshoot my strike water temperature around 5° or so; this will result in a little bit shorter time to reach the planned temperature in the mash tun.
  • My mash temperature settled at 154-156°, depending on where I measured it in the tun. It was down to 152° after 45 minutes. After 60 minutes, I added 0.75 gallons of water at 185°, let sit for 10 minutes, vorlaufed, and collected the first runnings. I then added another 3.5 gallons of water at 175°, which raised the mash bed to 160°. After sitting and vorlaufing, I collected the second runnings.
  • In total, I collected 6.4 gallons of wort at a gravity of 1.052, for 76% mash efficiency.
  • I started the boil, adding ingredients per the schedule. After 35 minutes of boiling, I added an additional 0.25 gallons of R.O. water, to bring up the boil volume slightly and drop the gravity slightly.
  • After a 60 minute boil, I turned off the flame and started chilling. Once I got down to 70°, I transferred the wort (while aerating with the usual Venturi pump and wort sprayer) into my primary fermenter.
  • My pre-fermentation volume was 5.25 gallons, up to 5.5 gallons (approximately) once I pitched the yeast.
  • Starting gravity was 1.060, close enough to my target for me to be happy (anything within 0.001 is well within instrument measurement error)! I’ll be fermenting at 68°. This batch was brewed on 2 January 2017.
