Countdown IPA

So named because we’re on the countdown to a new baby in the household…gotta brew while I can! This recipe is basically a minor tweak of my Centennial IPA, just mixing up the hops a little bit both for variety and complexity as well as to burn through a bit more of my stash. I also swapped in the US equivalent of the Belgian crystal malts, so that I didn’t have to buy more malt. Finally, I added a touch of Carafa Special II to deepen the color a bit.

Countdown IPA

  • 10.5 lbs. 2-row pale malt (Rahr)
  • 1.75 lbs. Vienna malt (Great Western)
  • 0.5 lbs. 20° caramel malt (Briess)
  • 0.25 lbs. 10° caramel malt (Briess)
  • 1.5 oz. Carafa Special II (Weyermann)
  • 1 oz. Amarillo hop pellets (7% alpha), first wort hop and 90 minute boil
  • 1 oz. Amarillo hop pellets (7% alpha), 15 minute boil
  • 2 oz. Amarillo hop pellets (7% alpha), 10 minute boil
  • 1 oz. Centennial hop pellets (7.6% alpha), 5 minute boil
  • 1 oz. Amarillo hop pellets (7% alpha), 5 minute whirlpool
  • 1 oz. Centennial hop pellets (7.6% alpha), 5 minute whirlpool
  • 1 oz. Ekuanot (HBC 366 aka Equinox) hop pellets (13.6% alpha), dryhop in keg
  • 1 oz. Simcoe LupuLN2 (23.8% alpha) cryohop pellets (23.8% alpha), dryhop in keg
  • 1 Whirlfloc tablet, 10 minute boil
  • 1 tsp. Fermax yeast nutrient, 10 minute boil

Target Parameters

  • Infusion mash to hit target of 149°. Batch sparge.
  • Claremont tap water with RO and salt additions to hit targets of 113 Ca, 22 Mg, 24 Na, 194 SO4, 42 Cl, 207 HCO3, 170 ppm alkalinity, 76 ppm RA.
  • 1.066 o.g., 1.012 f.g., 7.2% abv, 68 IBU, 9 SRM, 5 gallons into fermenter

Procedure

  • My base water for this beer was all Claremont tap water. I added 3.2 g of gypsum, 1.8 g of epsom salts, and 0.6 g of calcium chloride to 4.3 gallons of mash water, along with 45 mL of 10% phosphoric acid. I used the same masses of salts for 4.75 gallons of sparge water, with 50 mL of 10% phosphoric acid there.
  • I mashed in with 4.3 gallons of water at 157.3°, to hit a mash temperature target of 149°. I mashed for 90 minutes; at the end, temperature was down to 145°. I collected the first runnings after a vorlauf, and then added 4.75 gallons of sparge water at around 185°. I let the mash sit for 10 minutes before vorlaufing and collecting the remaining runnings.
  • In total, I collected 7.2 gallons of runnings with a gravity of 1.052, for 78% efficiency.
  • I boiled the hops per the schedule, adding the kettle finings and yeast nutrients appropriately. After the full 90 minute boil, I turned off the heat, added the final hops, whirlpooled for 5 minutes, and began chilling.
  • Groundwater is pretty warm this time of year, so I could only chill the beer down to around 85°. I transferred to the fermenter and then let it chill overnight (~10 hours) down to 66°. I pitched the yeast, and things had begun to take off within 18 hours.
  • Starting gravity was 1.064. I brewed the beer on 14 July 2017 and pitched the yeast early on the morning of 15 July 2017. I’ll be fermenting at 66°.

CA IPA

Time to IPA it up again! I’ve been doing a lot of either “fruity” hops (Citra/Mosaic) or single hop IPA experiments, so for this recipe I wanted to do an American hop blend focusing on Centennial and Amarillo (hence the name “CA IPA”). I’m also going to switch up techniques a bit–rather than dry-hopping in the keg, I’m going to dry-hop in the fermenter towards the end of the main fermentation cycle, followed by cold crashing prior to kegging.

CA IPA

  • 11 lbs. 2-row malt (Rahr)
  • 2 lbs. 4.8 oz. Vienna malt (Weyermann)
  • 8 oz. crystal 20° malt (Briess)
  • 5 oz. crystal 10° malt (Briess)
  • 0.75 oz. Warrior hop pellets (15.8% alpha), 60 minute boil
  • 1 oz. Amarillo hop pellets (7% alpha), 15 minute boil
  • 1 oz. Centennial hop pellets (7.6% alpha), 15 minute boil
  • 1 Whirlfloc tablet, 10 minute boil
  • 1 oz. Amarillo hop pellets (7% alpha), 5 minute whirlpool
  • 1 oz. Centennial hop pellets (7.6% alpha), 5 minute whirlpool
  • 1 pkg. Burton Ale yeast (WLP023, White Labs), prepared in 1.25L starter
  • 1 oz. Amarillo hop pellets (7% alpha), 5 day dry-hop in primary fermenter
  • 1 oz. Centennial hop pellets (7.6% alpha), 5 day dry-hop in primary fermenter

Target Parameters

  • 150° mash, 60 minutes
  • 1.065 o.g., 1.015 f.g., 6.6% abv, 63 IBU, 6 SRM, 6 gallons into the fermenter

Procedure

  • The morning of my brew day, I prepared the yeast in a 1.25L starter. I don’t plan on setting any aside, so I did not bother with overbuilding the starter.
  • I prepared my mash water by adding a quarter Campden tablet, 8g gypsum, and 5g epsom salt to 4.75 gallons tap water. The 4.5 gallons of sparge water will be plain RO.
  • I heated the mash water to 170°, added it to the fermenter, and then let the temperature settle to 161.5° before adding the grains. This hit my mash temperature right at 150.2°, pretty much exactly where I wanted it.
  • Mash temperature was down to 148.5° after 30 minutes. I was visiting with some friends, so the mash ended up sitting a total of 90 minutes before I got back to it. At this point, I vorlaufed and then collected the first runnings.
  • Next, I added the sparge water (at around 155°, to hit a mash bed temperature of 152°), let it sit for 10 minutes, vorlaufed, and collected the remainder of the wort.
  • In total, I collected 8.1 gallons of wort at a gravity of 1.050 and 78% efficiency. This is a larger volume than expected–I think this is likely because I had assumed my RO jug had 4.5 gallon exactly, and it was probably a touch more than this. I’ll measure more carefully next time! For this particular batch, I boiled a bit harder than usual to bring the volume down and the gravity up.
  • Once I had the wort at a hard boil, I added the hops per the schedule, boiling for 60 minutes total. At the end of the boil, I added the whirlpool hops (in a mesh bag) and let them sit for 5 minutes before chilling the wort.
  • Once the beer was down to ~75°, I transferred to the fermenter and pitched the yeast. I put approximately 5.75 gallons into the primary. I pitched the yeast, and will be fermenting at 67°. I plan to add the dry hops in 5 days.
  • Starting gravity was 1.060, a bit below my target (but not surprising given the extra boil volume).
  • I brewed this beer on 25 March 2017. Visible yeast activity was evident in under 24 hours.

Equinox IPA

I have been seeing a fair bit about Equinox…err, HBC 366…hops during the past year, and wanted to try them for myself. Like many of the recent American varieties, it is supposed to pack quite an aroma and flavor punch. Even if it’s totally stereotypical for a homebrewer, I do like big, aroma-rich hops, so a batch with Equinox made it onto my “brewing goals” list.

This was also an opportunity to continue my exploration of Vienna malt, so I crafted a SMaSH-ish recipe that had a decent late-hopping dose of Equinox. The only minor deviation from a true SMaSH is that I threw in a touch of de-bittered black malt for color.

Finally, I am using this batch to recalibrate some of my brewing parameters. For a few batches now, I have noticed that my wort volumes and starting gravities are a touch off, so I am going to adjust the mash and boil-off assumptions accordingly in BeerSmith. Additionally, the night before brewing, I completely disassembled and cleaned my mill (a Monster Mill 2). There was some grain dust worked into places, and as a result it wasn’t holding the gap as well as it should (hence my low mash efficiency on some previous batches). After reassembly, I set the gap to around 0.039″. As noted below, I had incredible mash efficiency (84%!), but the mash itself was a little slow to drain. So, after this brew I widened my gap to 0.041″.

Equinox IPA

  • 12 lbs. Vienna Malt (Weyermann)
  • 1 oz. de-bittered black malt (Dingemans)
  • 0.5 oz. Equinox (HBC 366) hop pellets (14.2% alpha), first wort hop
  • 0.5 oz. Equinox (HBC 366) hop pellets (14.2% alpha), 60 minute boil
  • 1 oz. Equinox (HBC 366) hop pellets (14.2% alpha), 5 minute boil
  • 1 oz. Equinox (HBC 366) hop pellets (13.4% alpha), whirlpool
  • 0.5 tsp. gypsum, added to boil
  • 1 Whirlfloc tablet, 10 minute boil
  • 2 pkg. Safale American dry yeast (US-05)

Brewing Targets

  • Mash temperature = 149°
  • Original gravity = 1.067 (actual = 1.062)
  • Color = 8.5 SRM
  • IBU = 63
  • Note that I originally targeted this for a lower gravity, ~1.058. Because I ended up with very high mash efficency (~84%), I had to adjust the recipe per the above. If I brew this again, after adjusting my mill gap, I’ll need to tweak the malt bill to reach the same gravity.

Procedure

  • I mashed in with 4.6 gallons of water at 159°, to hit a mash temperature of 151°. The mash was down to 147° after 30 minutes, and 146.5° by 60 minutes.
  • After 60 minutes, I added 0.7 gallons of water at 190°, to raise the mash bed to 148°. After 10 minute, I vorlaufed and collected the first runnings. Due to the fine crush, it took awhile to drain the mash bed.
  • I then added 3.75 gallons of water at 182°, to raise the mash temperature to 160°. I let it sit for 10 minutes, vorlaufed, and collected the second runnings.
  • Wow! I collected 7 gallons of wort at a gravity of 1.055, for 84% efficiency. As a result, I adjusted my original recipe to the one above.
  • As soon as the wort was on the flame, I added hops. At the boil, I added the second addition, and everything else was dropped in at the appropriate time.
  • After flame-out, I chilled the wort to 84°. This wasn’t quite cool enough to pitch the yeast, so I transferred into my fermenter and put it all into the fermentation chamber for a few hours. Once the overall temperature had come down, I pitched in the two packets of yeast.
  • Starting gravity was 1.062, a little lower than expected (probably due to a slightly lower boil-off rate than assumed by BeerSmith). I brewed this on 27Aug2016, and am fermenting at 66°.
