Test Pale Ale 1.0

Recently, I have struggled to get the desired final volume out of the Brewie+ system. To try and resolve that issue, I've decided to brew a couple of recipes and babysit the mash and sparge process to see where the problem is occurring, as well as double-checking my calculations to ensure they are correct.

The first test was this Pale Ale recipe.

Ingredients

5 pounds of 2-row Pale Ale Malt
1 pound of Munich Malt
4 ounces of Flaked Corn
0.75 ounces of Mandarina Bavaria hops pellets @ 9.2% AA at 10 min.
0.60 ounces of Citra hops pellets @ 14% AA at 5 minutes
1/4 tsp. Yeast Nutrient
1/8 tsp. Brewtan B in the mash water
1/4 tsp. Brewtan B in the boil at 10 min.
1/2 tsp. Irish Moss in the boil at 15 min.
1 packet of Lallemand Nottingham dry ale yeast
9.2 liters of mash water
3.2 liters of sparge water

The mash schedule began with a mash in at 104F, followed by 20 minutes at 140F, and 40 minutes at 158F. Mash out was 15 minutes at 168F.

BeerSmith estimated the following qualities for the beer:
  • BJCP Style: 18.B Pale American Ale
  • Batch Size: 2.5 gallons (actual was 2.5 gallons)
  • Original Gravity: 1.054 SG (actual was 1.054 SG)
  • Pre-boil Gravity: 1.034 SG (actual was 1.047 SG)
  • Final Gravity: 1.011 SG (actual was 1.013 SG)
  • SRM: 5.8
  • ABV: 5.5%
  • BU/GU Ratio: 0.656
Boil schedule:
  • 90 minutes: No addition
  • 15 minutes: Irish Moss
  • 10 minutes: Brewtan B, Mandarina Bavaria
  • 5 minutes: Citra
  • 0 minutes: Chill to 68F
Fermentation schedule is to place this in the corner of the basement with an ambient temp of 60F and leave it there. (In practice, this worked well. The beer never exceeded a temp of 62F throughout the brew.)

Post-Brew Notes and Observations

03/09/2019:  Thanks to carefully measured water, the beer came out very close in gravity and volume to the expected values. I had to add a little water to hit 2.5 gallons, at which point the gravity also hit my target value of 1.054 SG.

03/17/2019:  The beer has stayed within a degree of 61F throughout fermentation. Gravity is down to 1.013 SG, which is within a point of the expected final gravity.  I expect to bottle the beer within the next day or two.

03/19/2019: The beer was bottled with 5-6 small carbonation tablets per bottle. Yield was 24 bottles.

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

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 basket Cleaning the grain basket, kettle, recirculation tube, and wort chiller Cleaning 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 residu

Chapman Brewing Equipment 7 Gallon Stainless Steel Fermenter

Chapman's 7-Gallon Stainless Fermenter Recently, I found the Chapman Brewing Equipment 7-gallon SteelTank stainless steel fermenter on sale on Amazon for approximately $110.  That's about half the price of the other stainless steel fermenter I own, Ss Brewing Technology's Brewmaster Bucket. In fairness to the Brewmaster Bucket, the Chapman fermenter lacks a number of features.  The Chapman has no legs underneath it.  It's not designed to stack multiple fermenters on one another.  It has no thermowell or thermometer.  It doesn't have a conical bottom to catch yeast and sediment.  It also doesn't have a spigot you can use for bottling.  So the extra $100 buys a few features you're not getting here. That said, there is nothing wrong with this fermenter.  It seems very well made from 304 stainless steel.  There are good strong looking handles.  The gasketed lid can be clamped down for sealing and safety when carrying.  It even ships with a 3-piece airlo
