Beer Name: Fighting Irish Red

Style:  Irish Red

Alcohol: 6.87%

Color: 28

My second successful all-grain beer!  I decided to make a few adjustments to the original recipe.  I upped the grain bill instead of adding honey to keep the same ABV and replaced the 2 row pale ale with Maris Otter Pale to allow for a thicker mouth feel.  I tried it 2.5 weeks after bottling while home for thanksgiving and it was okay.  After 6 weeks the beer has hit its stride and is pretty nice.  The beer came out smooth, malty, and very tasty.  The head is a little off and collapses pretty fast, but it appears to be carbonated about right.  Definitely worth doing again, but I might make some minor adjustments to the hop schedule.

My Brew Notes

Execution Notes

I’ve always used RO water as I didn’t know what was in my home water for a long time.  When I finally figured out my water I learned that it comes from two sources which are pretty much on the opposite side of the spectrum and there is no way to know what is coming out when.  So I’ve continued to use RO water which is cheap at the filling station next to the grocery store (30 cents per gallon).  This was the first time I tried doing water adjustments from the RO water.  I bought some things last minute, but didn’t have anything to make Chloride adjustments.  I’ll work to get better at this, but was focused on doing too little rather than too much.

Had similar issue with the mashing again where I started hotter than planned and then dropped about 8 degrees over the coarse of the mash.  My numbers came out okay, so nothing to worry about on this batch but certainly something to work on.

I tried using a little pump from ebay to do a whirlpool (not a real whirlpool, but enough to keep the wort moving over the coils when chilling), but clearly wasn’t ready as I fussed with that for about 20-30 mins before giving up and just using a spoon to stir.

Other minor notes.  My measurements don’t seem to be too accurate as I gained wort from the post boil measurement to the fermenter.  Need to get better at that.  I allowed for 30 mins for the trub to settle and then used my filters for the post boil transfer which resulted in a very low sediment in the fermenter. I collected the yeast into a clean spagetti jar as practice for yeast washing.  The yeast came out really clean and if I do things right (sterile jar and water) it seems I can start re-using yeast in the future.

Recommendations for next time

  • When compared to a Red Seal Irish Red mine is more malty and not as hopped.  I think I’ll slightly up my hops a bit next time, but not too much.
  • Get pump to work
  • Take better measurements
  • Try harvesting yeast

Trying to start a project just as you become a dad isn’t the best plan, but I’ve finally completed my fermentation chamber after about 6 months.  I’m already making a beer in it and so far it is working great.  The ironic thing is that the temperature is about 70 degrees right now and the fermentation chamber doesn’t really have to do anything, but at least I’ve staying at a constant temperature.

First things first, here are pictures of the completed project  (click an image for a larger view)



I bought my things from four main places.  The temperature controllers came from E-bay, the A/C unit was from craigslist, the 110VAC lights, switches and relays are from, and the rest of the material was from Home Depot.  The box is made of 2x4s, 1/4 plywood, and 2 inch foam.  I used foam glue to attach the plywood to the foam and 2″ screws to join all the 2x4s.  To join the foam pieces together and cover holes I used Great Stuff.  After I add up all the pieces I spent just a bit under $500.  I bought a few tools, but was able to borrow most of the big tools from family and friends.  The most surprising thing was how expensive outlets, outlet boxes, fuse holders, and  the controller box were.

The Build

Overall the project came together pretty close to the plan.  I can’t cut straight, follow my directions, or paint, but other than that I did pretty good.  The borrowed tools really helped cutting relatively straight lines, not straight, but straight enough.  When I built the controller box I had a few errors that needed correcting, but that was fine and not completely unexpected.  I also didn’t like how my doors were going to seal so I added another foam border to help with that.

The control box almost was a disaster.  I used a bremel to cut out the switches with no problem.  The wiring went to plan.  I did have a bit of difficult soldering the wires to the switch contact points, but eventually got it.  the I used a few contact boards to provide a secure attach point for the external wires to the internal wires.  At the very end I almost couldn’t get the lid to close.  I had to move and twist the wires around and apply some pressure to finally seal things up.  I had two mistakes during this build.  First, my initial wiring for the relay looked really good, but upon testing I discovered that I did about 50% of the connections wrong and had to redo it all.  Finally, once it was all sealed up I discovered that my compression did break a couple of contacts that I had to go in and fix.  But in the end the controller works great and looks pretty good.

As an extra thing that I worked on while I couldn’t get down to the garage is that I converted two old cell phones into IP webcams, one to watch the control panel and the other inside the chamber to watch the fermenting process and to double check temperatures.  To get my wifi signal to reach the garage I had to setup a wifi repeater.  The two phones were android phones and I was able to use free apps to setup the webcams.  I installed IP Webcam for the webcams, droid VNC server to get into the phone remotely along with Screen Widget to turn the screen off (if needed).  Finally, I can watch the webcams with the built in webpages from IP Webcam and I also use IP CAM Controller to see things from my phone.  I had planned for this which is why I have an outlet not controlled by the STC-1000s so that the internal cell phone could remain on all the time.

Looking Back

Now that I’ve build my project I think I’d do it a bit different next time.

  1. I’d probably simplify all the cuts I have to do and make the outer plywood fit around the foam entirely then have the 2×4 brace around it.  This would make the project cost just a bit more, but it would save so much time.
  2. I’d make the doors fit flush with the outside edges rather than fit inside the openings to make the seals easier.  I didn’t follow my original plan for the doors as I was worried they wouldn’t seal well.
  3. I would make the A/C cutout a bit larger.  This ould make it easier for the great stuff to get in the cracks.  I didnt’ have much space and don’t really know how well I sealed this in. (I’m yet to do a dry ice test).
  4. I was excited and cut the foam pieces first, but looking back I should have made the frame and then cut the foam to fit into it.  I’m pretty sure my method is a rookie mistake, but I was excited to see the foam cut out.

 Next Steps

I haven’t made the dividing section so that I can have two temperature zones inside.   I have the controller and the wiring all done and all is left is to figure how I would do this.  I’m thinking some type of relay to open and close a small opening and then a fan to circulate air.  I also have to figure out how to make the section so that it can be moved around and then “expanded” to give it a tighte fit.  I’ll have to think about this for a while, until then…

After my last batch of beer, Baby-T Double Trouble Belgium Dubble, came up short on the alcohol content I’ve decided that my problem is due to my fermentation temperatures…and possibly my aeration.  I was also having a hard time using my wort chiller since the hose water that I’ve circulated through it wasn’t too cold.  So I’m stepping it up a notch.

I got a drill off of Craiglist for about $20 and a drill water pump from Home Depot.  Next time I chill the wort I’ll be circulating iced water from a cooler through the chiller which should bring the temps down right away.  I also bought a large drill-attached paint mixer to help aerate the wort after it is chilled.  One thing I’m slightly hesitant on is that while I plan to sanitize the mixer, I don’t know if I’ll run into any problems since it isn’t a food grade mixer. I guess I’ll learn soon enough.

Now to the main issue, temperature control.  For all my batches to date I’ve simply left the beer to ferment in the back of the garage.  The temperature usually stays around 60 degrees, but on really hot days it will rise to 70 and on consecutive cold days it will drop to low 50s.  For my last batch I started fermenting right as a cold spell hit which I’m pretty sure caused the yeast to not ferment all the sugars.  After a lot of reading the only way I’m going to get around the problem is to get some temperature regulation through a fermentation chamber.

I did a lot of reading in the forums to get ideas of how to go about building a fermentation chamber.  I think there are basically three types of chambers, those that use ice, those that use a fridge components, and those that use air conditioners.  The ice ones are simple (1,), but if you ask me annoying to maintain. The fridge styles have many variations.  Some work as is, some take some cutting of the interior to make room for a carboy (1,2,), some look to extend the fridges dimensions with some type of add on (1,), and others strip out the cooling component and then use a custom box (1,).  For the AC styles they are pretty much the same, take an AC unit and build a custom box (examples below).

Our garage is already packed with stuff, so the custom box idea was the most attractive to me.  The next part was to decide fridge or AC which is the single most expensive part.  I simply trolled Craiglist for a while until I found something cheap.  For me it ended up being a $30 Haier 5000BTU AC unit (HWF05XCK-1) which I learned was purchased from Target the year prior when we were having a huge summer heat wave and the person selling it was moving to Saudi Arabia.  I joked with the person that they probably should have taken the unit with them, but assured them that I’d put it to good use. Anyways, just as noted in the Racer X design to override the temperature cutoff on the AC unit a simple loosening of the screw behind the temperature knob will do the trick.

The screw is here (hard to see)

This is the other side, do not mess with this screw

With the screw loosening I rigged up a quick test to see that I did things just right

The temperature is down to 36 degrees F!

With the AC unit and the idea to make a custom box, I needed to sort out the temperature controller.  I very very long forum about an aquarium temperature controller that can be bought on ebay seemed like the ticket for me.  This controller usually can be bought for $15-$20 and I got my first one for $15.50 and the second for $18.25 (I’ll explain later…which if I knew how to do ebay better should have been $17, but I’ve wasted $1.25 on worse before). Here is a quick look at one with my measurements marked up on it:

Now off to design the chamber.  My design was strongly influenced one the 2 Tier, 2 Zone fermentation chamber (Racer X).  It is a really nice build and as it turns out I ended up with the exact same AC unit as his (even though they are listed as different brands).  This chamber is really nice as it allows for one cooling unit and two temperature controllers to create the two zones.  There are a few others with similar ideas that I looked at too (1, 2, )

I decided that while I really like the 2 zone idea I don’t need that right now, but that I’d make my design with a future expansion in mind.  I wanted to make sure that this could hold a keg plus kegging gear, 3 soda kegs plus gear, 4 carboys, or 4 5G buckets, or 2 buckets and all of my other brewing gear so that I’m not scattered all over the garage.  With this in mind I settled on an interior dimension of 34″ x 36″ x 24.5″ (height, width, depth when looking at the front).

Additionally, here are a few design notes that I took from all my forum reading

  • Use the best (i.e. highest R-rated) rigid foam.  A look at Home Depot says there is a 2″ foam with an R-10 value that is moisture resistant
  • Seal all the edges to avoid air leaks
  • A 2×4 is not 2″ by 4″.  It is really 1.5″ x 3.5″
  • On the interior paint the inside with a mildew resistant paint and caulk the edges.
  • I want easy access to the interior.  No top doors so that I can leave things on the top.
  • 20A requires 12 guage wire.  10A requires 18 gauge.

I messed around for a bit trying to figure out how I would go about designing this.  When I did my bar a few (many) years back, which I’ll post about some other time, I did it all in excel where each cell represented 0.25″.  that worked out well, because a quarter inch was the smallest thickness of wood that I used.  For this design I plan to use 1/8″ plywood and excel just won’t work as there are too many cells needed.   I ended up doing the design the simple way, engineering paper, a ruler, and a pencil.  For the most part I had each square represent 2″. The 1/8″ is hard to draw clearly, but I made it work.  I won’t go into all the effort spent making the design, but below are the drawing for the chamber.  As in the Racer X design, the doors are the hardest part. I decided to have two doors that swing open from the sides. If you look carefully at the design, I’ve staggered the plywood and foam cutting one inch from the sides, the top, and between the doors. With this staggered approach the doors actually don’t come together in the middle, but I have a door cover that makes it appear as if it does. I need to sort out how to add the weather stripping, but for now I’m planning on just slicing a bit of foam away from the edges for it. The other thing that I know I have left off is the hole for the AC unit.  I’m planning to simply cut as needed and figure the support required to keep it at the proper angle (note the AC unit isn’t supposed to be level.).

Once I had the design drafted I determined how much wood and foam I’d need. I was able to get it down to 13 2x4s, 2 foam sheets, and 3 plywood sheets.

The next thing I needed to sort out was how I was going to wire the chamber up. The temperature controller forum had a lot of good ideas. I decided that I’d have one outlet for the hot, one for the cold, and two for either hot or cold. I also wanted to be able to turn the outlets on and off without unplugging them so I needed a switch. I added some indicator lights. I added another switch for another outlet that I can keep on the outside of the chamber. I’m going to wire up the second temperature controller to just be a simple thermometer since the temperature probe on the beer will be slightly different due to the exothermic reaction of the yeast fermenting beer. I plan to have this whole circuit plugged into a 20A circuit, but the temp probes are only rated for 10A so I’ve added a 10A fuse to each circuit. 10A will be plenty as the AC unit is only ~4A and I don’t intend to pull a full 20A at once. As I mentioned above I got the temperature controllers off of ebay. I found a really good deal on switches, relays and indicators from and now just need to get the outlets, wire, and boxes.

So that is all the planning which I did before my birthday. In hopes of getting some home depot gift cards I’ve waited a while to actually get going on this. In my free time which is very limited now that we have baby Chase on our hands I modeled the design in Sketchup. This took me a bit of learning to be effective at this, but after a short while I got the hang of it and was able to put together the plans. Good thing too as I learned a few things that caused me to make some adjustments in the design.

For my birthday Lisa got me a home brewing kit from South Bay Brewing Supply in Torrance and had picked out a wheat beer.


With some help from Alex, Tom, and You tube we set out to create the first batch

It didn’t seem like the stove could get things hot enough to keep this at a full boil so I was somewhat worried that the flavors wouldn’t turn out right.  On top of that when we  pour the wort into the fermenting container I think we got too much of the bottom gunch and was worried that the flavor would end up weird.  But we packaged it up and let it ferment for 2 weeks

After 2 weeks I took the top off and saw this

I wasn’t too sure if this was a good thing or not, but continued on.  I siphoned the beer into another container and added the priming yeast and sugar.  Here is my bottling operation

I tasted it here and it was not good, but continued on with the bottling and let it sit for 2 more weeks.  I was pretty certain that I messed up somewhere.  After 2 weeks Alex and I tried a couple bottles.  It fizzed when I opened it so I knew I didn’t kill the yeast.  The color is pretty nice and best part it tasted pretty good.   The next week we had an opening happy hour on the  roof.

One 5 gallon batch makes ~50 bottles of beer so now I have a full fridge of beer in the garage!

So the beer tastes pretty good, but I’m not too sure how much alcohol it has in it.  According to my measurements the starting gravity is less than the ending gravity, but it is supposed to be the other way around.  If I play with the numbers a bit it might be a 3.2%, but who knows and it still tastes good.

This Memorial day we had some great weather and got to beach it and some burgers on the roof.  We put a good dent in Batch #1 and due to my outstanding success I hope to make another batch of beer in time for July 4th!
