Olde Fortran Malt Liquor

I've been a fan of the now-defunct (again) series Futurama since it first aired. In that series, the alcohol-fueled robot Bender B. Rodriguez was often seen guzzling bottles of a beer named Olde Fortran Malt Liquor.

While there is no way to know what a fictional cartoon beer might taste like, the name of the brew is similar to Olde English, an American Malt Liquor that is produced by the Miller Brewing Company.

The American Homebrewers Association lists a recipe for a hypothetical clone of Olde English.  I decided to brew that with the Zymatic and see how it turned out.  I scaled the recipe down to 1.2 gallons to match one of my small glass fermenters and got to work...


15 ounces 2-row Pale Malt
14 ounces 6-row Pale Malt
13 ounces Flaked Corn
0.1 ounces of Cluster hops @ 7.7% AA (105 min.)
0.1 ounces of Nugget whole hops @ 14% AA est. (10 minutes)
1/4 Whirlfloc tablet
1/2 packet Safale K-97 dry yeast

1.5 gallons plus 13 ounces of water were placed in the Zymatic keg, then the grain, hops, and Whirlfloc were loaded into the hop bins. The brewing program was downloaded and started on the device.

According to the Picobrew web site, the beer should have the following characteristics:
  • Original Gravity: 1.056 SG
  • Final Gravity: 1.008 SG
  • IBUs: 15
  • SRM: 3
  • ABV: 6.2%
  • BU/GU Ratio: 0.27
  • Starting Water: 1.6 gallons
  • Batch Size: 1.2 gallons

In actuality, I ended up with about 1.67 gallons and ended up boiling it down to about 1.2 gallons and a final gravity in the 1.061 range - outside the Zymatic.


The high-efficiency mash program for the Zymatic was modified using the Advanced recipe editor to the following specifications:
  • Dough in at 102F for 20 minutes
  • Mash at 122F for 30 minutes
  • Mash at 150F for 66 minutes
  • Mash out at 175 for 10 minutes
During the mash, the Zymatic seemed to run low on water in the keg. As a result, it began sucking in air and foaming up such that I lost quite a bit of wort to foam. I ended up pausing the program and adding more water to the keg to stop the air intake. I also cleaned up as much foam as I could from the lid of the tray and applied some anti-foam.  The rest of the mash finished without incident.

Gravity post-mash registered at approximately 1.037 SG.  Considering I was aiming for 1.055, that seemed pretty low, but adding a lot of water to the keg certainly diluted it. I probably over-did it.


A 105 minute boil began, with the following schedule:
  • 105 minutes: Add Cluster hops
  • 10 minutes:  Add Whirlfloc and whole Nugget hops
When the beer finished boiling, I took another gravity reading. This time around it was still well below the estimated 1.055 SG I expected, so I transferred it into a kettle and boiled it down. Quantity at that point was about 1.7 gallons (approximately), which was far more than expected.

With about 30-40 minutes of boil time, I reduced the wort quantity down to about 1.2 gallons and the wort gravity increased to 1.061 SG - higher than expected but close enough to suit me.  I chilled the wort with an immersion chiller and transferred it to the fermenter.


A half-packet of Safale K-97 (Kolsch) yeast was added to the beer before sealing up the fermenter.  Although Olde English is reportedly fermented with lager yeast, I didn't want to deal with a lager this close to Christmas.

K-97 will reportedly brew with lower esters than US-05 (which I was out of anyway), less superior alcohols, and less residual sugar.  It's also supposed to flocculate well after fermentation is over.  Hopefully the low level of esters will make a for a beer that's "close enough" to a lager, especially fermenter in the cool basement temperatures.

I had already used the other half of the packet for the Blonde Ale I brewed earlier in the day, so I used the rest with Olde Fortran.  The yeast reportedly works ideally in the temperature range of 59-68F, which is about the ambient temperature in my basement this time of the year.

Post-Brewing Other Notes

Although the Zymatic is billed as a "set it and forget it" device, I'm finding that it's important to keep an eye on it during the first 30 minutes or so of the mash process. If you don't do that, it seems prone to generating a lot of foam that will push its way out of the tray (or "step filter") and possibly outside the unit (onto the floor).  After the main mash is well underway, if it's not foaming at that point it is probably going to finish fine. So far, I've had no issues with foam during the boil.

01/02/2018: A look in the fermenter shows that the K-97 yeast made a massive and thick krausen that made a real mess of the sides of the glass fermenter. Fortunately it's a big-mouth fermenter so cleanup won't be an issue.  The krausen appears to mostly be gone now, so I suspect fermentation has ceased. I'm debating transferring to a clean secondary and pitching some gelatin, then refrigerating it.

01/06/2018:  The beer was bottled today. The one-gallon batch actually yielded 11 bottles. The beer is a hazy gold color. Coopers Carbonation Drops were used to prime the beer at bottling.  The bottles were then placed in my "hot box" which will keep them at 80F until I remove them, probably next weekend. A sample left in the bottling bucket was light-tasting and moderately bitter.  Nothing to write home about, being neither particularly good or particularly bad.

02/10/2018: The beer has had a while to condition and clarify, so today is the official taste test. As you can see in the image below, it's a nice gold color with thick white head that lasts about a minute before reincorporating into the beer. It's not crystal clear, but only slightly hazy. The aroma is malty with a touch of corn. The flavor is malty, slightly sweet, with just enough hops bitterness to balance it out. I've never had an Olde English, but given how much this reminds me of a mass-produced American beer, I have to think it's close. Is it what Bender would have guzzled on Futurama?  Maybe, though I'd imagine Bender drinking something with a much higher alcohol content.

Grainfather Specifications for BeerSmith, Beer Tools Pro, and Other Software

Recently, I've been trying to "dial in" settings in BeerSmith and Beer Tools Pro so that I can do a better job getting my actual brewing results to match up to the figures in the software. Below are some of the figures I've worked out with my US Grainfather. Given manufacturing variances and possible measuring errors on my part, these might not match exactly to yours, but hopefully they're close enough that it will help you. BeerSmith Equipment Profile: Brewhouse Efficiency: 83% (based on my experience, yours may vary) Mash Tun Volume: 8 gallons Mash Tun Weight: 8.82 pounds Mash Tun Specific Heat: 0.12 Cal/gram-deg C Mash Tun Addition: 0 gallons Lauter Tun Losses: 0 gallons Top Up Water for Kettle: 0 gallons Boil Volume: 6.25 gallons Boil Time: 60 minutes Boil Off: 0.40 gallons per hour Cooling Shrinkage: 6% Loss to Trub and Chiller: 0.53 gallons Batch Volume: 5 gallons Fermenter Loss: 0.40 gallons (yours may vary) Whirlpool time: 0 minutes B

Yellow Label Angel Yeast vs. Typical Brewing Yeast

I currently have my second batch of rice wine fermenting with the "magical" yellow-label Angel Yeast from China, and wanted to share some of the more unusual aspects of using it.  If you've never seen or used this yeast, I suspect you're not alone.  It ships in a 500 gram package that looks like this: What makes it "yellow label" is that yellow box you see in the upper left corner of the package.  This implies that it's yeast for distilling (though you do not need to have a still or distill the output to use it).  As I understand it, inside the package is a mix of yeast and other materials which will convert starch into sugar and directly ferment it, without the need for a traditional mash step.  This can radically shorten your brewing time.  For my most-recent batch of rice wine, I heated 3 gallons of water to 155F, poured it over 13+ pounds of uncooked rice straight out of the bag, let that soak for an hour, rehydrated some of this yeast in warm water,

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
