Hoppily Ever After 1.0

My step-son and his fiancee love big, citrusy IPAs. They would like me to brew one that could be given away as a favor to guests at the wedding. Not being a fan of IPAs in general, I don't have a recipe ready. Even if I did, I'd want to put a twist on it so that it's unique to them.

Reviewing the information I could find on NEIPAs, I learned the following:
  • Include high-protein malts (wheat, oats) in the grist to add body
  • Use fruit-forward hop varieties
  • Few kettle hop additions, more whirlpool hops (a challenge in automated systems)
  • Ferment with low-attenuating, low-flocculating, ester-forward yeast, like London Ale, Dry English Ale, or Vermont/Conan
  • Dry-hop during primary fermentation to allow yeast and hop qualities to bond
  • Stay below 65 IBUs (generally)
  • 1-3:1 chloride to sulfate ratio in the water (150-175 ppm chloride, 75-100 ppm sulfate)
  • Dry hop with 0.5 to 1.3 oz. per gallon, added within 2-3 Plato (8-12 SG points) from final gravity
  • Add most of the hops at the end of the boil or in whirlpool to avoid harsh bitterness and get more flavor/aroma
  • Mash in the 150-152F range
My plan is to mix barley, wheat, and oat malts to get a nice body in the finished beer. They've asked me for a citrusy IPA, so I'm going to use a blend of Amarillo, Mandarina Bavaria, and Cascade (which all have citrus flavors in them) late in the boil. Although there's not really a whirlpool stage in the Brewie's process, I'm planning to drop the hop cages into the kettle during chilling to simulate that effect. I'll use an English Ale strain for the esters.

Ingredients

6.5 pounds of 2-row Pale Malt
0.5 pounds of Wheat Malt
0.5 pounds of Flaked Oats
0.5 pounds of Rice Hulls
6 ounces of Carapils/Dextrine Malt
1.4 ounces of Cascade hops @ 6.9% AA (6 min.)
1.4 ounces of Mandarina Bavaria hops @ 9.2% AA (5 min.)
2.8 ounces of Amarillo hops @ 8.6% AA (1.4 at 4 min., 1.4 at 3 min.)
1/4 tsp. Yeast Nutrient
1 packet Lallemand ESB yeast
1 tsp. Calcium Chloride added to mash water
3.0 gallons of mash water
1.7 gallons of sparge water
1 ounce each of Cascade, Mandarina, and Amarillo in primary as dry hops

BeerSmith reports that the beer should have the following characteristics:
  • BJCP 2015 Style: 21.B Specialty IPA (New England IPA)
  • Batch Size: 2.5 gallons
  • Total Grain: 8.38 pounds
  • Total Hops: 8.6 ounces
  • Pre-Boil Gravity: 1.055 estimated (1.066 actual)
  • Original Gravity: 1.069 SG estimated
  • Final Gravity: 1.016 SG estimated
  • Brewhouse Efficiency: 60% estimated
  • IBUs: 60
  • ABV: 7.0%
  • SRM: 5.2
  • Mash pH: 5.59 estimated
This all fits within the NEIPA style.

Mash Schedule

The mash schedule will be:
  • Mash in at 120F for 25 minutes (beta glucan rest for wheat and oat)
  • Mash at 152F for 60 minutes (mash for fermentability)
  • Mash out at 168F for 10 minutes
Periodically during the mash, I would move the bag around a bit and poke it gently with a plastic grain scoop to help ensure the mash water was flowing through and around it. I hoped this might help with starch conversion.

Boil Schedule

Mixing the typical whirlpool hopping style of a NEIPA with the way automated brewing systems work, we end up with hopping during the last 5-10 minutes of the boil. My plan will also be to remove the hop cages from their slots and drop them into the beer during the chill process to add more flavor and aromatics. That means our schedule will be:
  • 60 minutes: No hop additions
  • 15 minutes: Yeast nutrient
  • 6 minutes: Cascade
  • 5 minutes: Mandarina Bavaria
  • 4 minutes: Amarillo
  • 0 minutes: Move hop baskets into kettle to simulate whirlpool hopping
The Brewie+ will chill the wort down to 65F in preparation for fermentation.

Fermentation Schedule

The plan is to keep this toward the lower end of the yeast's optimum temperature range (65-72F) to minimize the production of esters. Lallemand ESB yeast is a medium attenuation strain with low flocculation, which should make it a good fit for the style.

When the gravity is down into the 1.028 to 1.020 range, I'll add dry hops (one ounce of each of the hops used in brewing) to add aroma. When the final gravity is reached, I'll bottle with 1 large carbonation drop (medium carbonation) per bottle and hold it at ambient basement temps until carbonation completes.

Post-Brew Notes and Observations

12/27/2018: I began the brew day by re-calibrating the Brewie+ weight sensors to ensure that it loads the correct amount of water into the mash and sparge processes. This took longer than I remembered, but it's recommended to do this occasionally. I think I've made four batches in it since the original calibration, so it seemed like a good time to re-calibrate.

This recipe uses a bit more hops than I think are recommended for the Brewie+, but since I plan to drop them into the wort after boiling to simulate whirlpool hopping, I'm hoping that will be OK.  I'll plan to be with the machine at the end of the boil to be sure.

10pm: The beer came out high on gravity and low on volume. I added steam-distilled water to it, which brought the volume up to 2.5 gallons and dropped the gravity to 1.069 SG, which is exactly where I wanted it to be. The temperature was 71F at that point, within the yeast's range of 65-72F. I sprinkled the dry yeast on top and sealed up the fermenter, without temperature control for now. With the basement in the 63F ambient range, the beer's temp should get quite a bit lower before the yeast kicks in. I'm hoping it can free-ferment, but we'll see.

The kettle had a nice grapefruit/citrus aroma during chilling. Unfortunately, this was a lot of hops for the Brewie+ to handle. There was quite a lot of hop residue in the bottom of the kettle at the end of the boil, enough that I actually scooped a lot out before running the cleaning cycle. I ran both a Sanitizing and a Full Clean cycle after this batch to do my best to get the Brewie clean for its next run.

12/29/2018: The beer is now reading 1.030 SG and 66F. Gravity is dropping much more slowly now, so I may need to increase the temp to encourage the yeast to finish out the last 14 points or so.

12/30/2018: I added a packet of US-05 yeast to try to encourage the last few points of gravity to ferment away. Gravity is reading 1.027 SG. I also added a half-ounce of Amarillo and Mandarina Bavaria hops to dry-hop the brew.

1/3/2019: The US-05 was apparently overkill for this beer. It has fermented down to 1.003 SG, making the beer 8.5% ABV instead of the intended 7.0%. If the gravity holds until Saturday, I'll bottle it.

1/6/2019: Gravity is reading 1.002 SG now, and has been holding at that figure for about two days. I've decided to go ahead and bottle it, as I doubt it can get much lower. I bottled it with 4 small carbonation tablets per bottle (medium carbonation) and placed it in a 69F "hot box".

1/12/2019: I opened a bottle of the beer tonight to check in on it. The beer seems to have carbonated nicely. The hope flavors seem a little less bright now, but present. A little diacetyl was detectable, but that should go away in a little while.

1/19/2019: I removed the beer from the "hot box" I'd been keeping it in so that I could raise the temperature for another beer that's in the box and hasn't carbonated. I've found in the past that beers seem to age faster when kept in a warm environment, and that would spell the death of an IPA or Pale Ale.

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…
