My journeys in beer brewing
Up until now I had been using British Ale yeast with my EPAs. It was time to see the flavor difference switching to a California Ale yeast. Along with that change I wanted a more in-style color. I switch my Crystal Malt 80 and Special B with a Crystal 20 Malt. I kept the Maris Otter for consistencies so the yeast would be the big change in the recipe.
This began a back-to-back weekend of brewing. We had just come north from our 2+ weeks in San Diego, which included attending the Homebrewer's Conference. I had a new water pump for my chiller system and was ready to go. During the brew I had a few mistakes along the whole process.
With this batch I agitated the steeping bags a lot to make sure the grains were well soaked. In the C2 brew, I had dried the grains to give to a friend to use for bread making. I had found a few small clumps of grains and wanted to avoid a repeat. Months later with later batches, I realize that technique may be causing me problems with gravity and clarity.
I let it boil over. For whatever reason, I got distracted by pruning a plant. With only 3.5 gallons of water, it still climbed over the 8 gallon kettle. It was all foam, but it was a reminder to not get distracted. I maintained a mild boil with the lid on, much like with C1, so I felt my water level would be good with less evaporation.
The final issue was it took me a while to cool down the wort. When I tested the new pump the day before, I thought my at least as strong as my father's. But when I hooked everything up, the water could not push through as much hose with all the elevation changes. I changed the hoses configurations and did not go through the hottub for pre-cooling. That took about 10 minutes of sitting before cooling started.
The original gravity came out 6pts (0.006) above target. I scratched my head on that a lot. This might have been the result of my agitating during the steep too much, but 6pts seemed to high for just that. I have yet to find a good way to measure how much wort I have after boil, so I could only speculate that the boil over may have taken out more than I thought.
During fermentation I was treated to a enjoyable show of yeast in action. The California Ales yeast was more vigorous than then others and the currents were fascinating. Because I was brewing on back to back weekends, when I transferred to secondary, I had to leave my 3 gallon carboy outside the fermentation fridge, I tried to keep it cool in the closet, but it was probably around 72-74F. My final gravity came out to be 2pts (0.002) higher originally expected, but hitting target gravity after the original gravity adjustment.
One other thing I did was try to cold crash the beer to settle it before kegging. Here was were I ran into another problem. At the time I did not have a second airlock. So I used the old fashion blowoff tube in a bottle of alcoholic water (half water-half vodka). I moved the whole setup into the fridge to crashed it and I neglected to check my alcoholic water level. The next day I saw this layer on the top of the water and the alcoholic water cup tipped over. I thought the layer was ice, but moving the carboy showed it was liquid. My guess was during cool down it sucked the liquid into the carboy. Not knowing the water level in the cup didn't help. After some discussions with my brewing friend, I siphoned the beer below the layer into the keg and dump the rest.
The beer turned out fine with good in hop flavor. There was clearly more hop flavor in this APA than the C2 version. It could have used more, but that could be fixed by the recipe. What was unexpected was a bitter taste. I initially thought it had to do with the layer in the carboy, but my friend thought it was DMS. At this point I had already brewed my follow on batch the same way as this beer, so I was wondering if that beer would suffer the same fate. Over time the bitterness faded, pointing to a transient issue, not infection, and probably DMS. The solution to DMS was the boil without a lid. Since I had always brewed with a lid, I was unsure why I hadn't seen this before, but I guess that's why brewing is hard to repeat.
So I took the recipe I modified from C1 and tried it out. C1 only had 7 grams of Citra with 5 minutes left in the boil. With C2 I added a 14 grams of Citra at flameout. Otherwise everything was the s
ame Maris Otter, Crystal Malt 80 and Special B.
A lot of the picture show more of the later stages of this brew process because I was trying a closed system for cooling the wart. I borrowed my fathers submersion pump and put it in a bucket on the ground which pumped cool water into the wort chiller. The return from the chiller went through a garden hose that ran through the hottub, i figured I might as well use the 70F water to my advantage as every bit of cooling helps. The garden hose then went into my bottling bucket full of ice with it's pour spout open above the submersion pump bucket. Everything went will until I was about 80F and the pump turned off. I ran off the faucet the rest of the way and was fine. I was never able to get the pump back on. It didn't overheat, but something must have jammed it.
Months later my father tried the pump again and it turned on, so he took it apart and saw the pump oil was only a 1/4 full. It is a very old pump, so it took a while to find the oil, but after he did he filled it up and it works without problem.
Back to the beer. My brew process went well this time. I didn't forget anything during the process. This batch I got a bigger boil, unlike the steady low boil I had with C1. As a consequence, the beer was volume was lower and the original gravity was 2 points higher than expected. Tasting the wort I felt it was better than C1, so I was anxious to see how it turned out. When I calculated how much wort there was and added the extra evaporated water into BeerTools, the gravity came back into line.
I kegged this beer as we were having a late May hottub party. My friend brought his gear to serve his Wheat EPA and my C2. The C2 didn't disappoint. Everyone like it and kept going back to that tap. I was pleased with the flavor, it had a bit of that maltiness from the Maris Otter with a gentle Citra note. My friend would ways say it's a good American Pale Ale and that I was off-style by saying it was an EPA. I didn't mind and I wasn't too concerned with names.
I brought it to our Worts of Wisdom brew club meeting and people there like too, so it was good to see peers giving it a nod. I got a comment about style again which was fine.
I have not been a fan of high IBU beers. I like malt characteristics of English-style beers, so I found an English Pale Ale (EPA) recipes with Maris Otter, Crystal Malt, and Special B. Instead of Kent Goldings switch it with Citra. I know Citra is not an EPA hop, but it was my experiment to see how much the flavor changed. I used the same hop weights as the recipe, so I had a one to one comparison. If there weren't a lot of Citra characteristics then I'd still have a drinkable beer. If there were a lot more flavor, then I'd know how much the oil differences between Citra and Kent Goldings affect the flavor.
My recipe was for 3 gallons. From the start I wanted to make smaller batches so I could experiment more. I don't drink everyday and I don't want a bunch of beer lying around. What beer I do brew has encouraged more hottub parties at my house, so maybe not a bad thing for my friends.
My wife was away so I went to my friends place, kettle in-hand, to brew with him as he was doing an EPA partial mash. Side note, For my friends brew, he had a mystery grain in his cabinet so he through it into his mash tun. Turned out to be a wheat malt so
that beer was forever named a Wheat EPA. We had to take a trip for more propane with my friend's burner which allowed my steeping to fall to 140°F before warming it back up to 155. There were a few mishaps. I forgot my clarifier and I put in the chiller late which made me run the boil a bit longer. Probably hurting my hop flavoring a bit, but only a few minutes extra. Nevertheless, I hit the target gravity and was ready to ferment. The 3 gallons looked a bit funny in the 6 gallon carboy. Luckily the thermowell that had finally came in stock at MoreBeer. Also luckily it was long enough to reach the wort.
Even before I got home I felt it was going to be too light of hop flavor. I modified the recipe and planned to brew another batch when the fermentation fridge was empty. I named this beer C1, and the following on recipe C2.
The end result was only a hint of Citra. It was a drinkable beer, just not a lot to distinguish it.
With a brand new pot and burner, we began brewing our Amber with our brew-buddy Marvin (right). Again the winter weather of March 2015 gave us near 70°F day. Our friend wasn't there yet when we started brewing so we went off the kit instructions. As we began, I realized the instructions were different from what we did with our friend. Previously we targeted 155°F to steep the grains, but the instructions say to heat up to 170°F and let the temperature fall. I'm not sure the difference as everything I've read about enzymes and such that you want to extract from the grains that the temperature should be around 155°F
The brewing process went will, although I would later realize after bottling that it came out really dark for a Blonde when compared to one of my favorite Blonde beers, 805. Even so much that I inadvertently started calling it an Amber.
One thing I didn't like what we did at my friends house was to waste the water using the chiller. Dumping it not the lawn was not efficient. Knowing that some day soon we'd be on water rationing, I decided that this was the day we would fill our hot tub in our recently purchased house. The idea worked well as I filled about 1/3rd of the 5 person tub. From the picture (second on the right) you can see the hose ready to be deployed
One of the projects I had undertook before this brew day was the construction of a fermentations fridge. In what I can only describe as fate, a few months before this brew day a friend had asked if we wanted their wine fridge of 10 years for free. It was slightly noisy, but nothing that would keep you up at night and couldn't beat the price. When I realized I should convert the wine fridge, I started searching online. I ended up buying a two stage warm/cool temperature controller from MoreBeer. I cringed at the thought of spending a $150 for it, but I figured the fridge was free. I later realized I could have built one for a lot cheaper, but knowing me it would have been many months before I finished the project.
After hookup up the controller and putting wires through the foam, I had the perfect fermentation fridge that was less needed in March, but certainly was needed during the summer in our non-AC house.
I had taped the temperature probe to the side of the carboy because the thermowell I wanted from MoreBeer wasn't in stock. I like the one with the stopper on top, not the hood. Personal preference.
The beer in the end was ok. It had a buttery note to it and I wasn't thrilled with the color and flavor, but for my first beer, it was a success. I didn't kill it.
Our first brewing experience was a partial mash and mostly watching. Our friend, who has brewed for many years, showed us the ropes with our stout kit. It was good to see the more advanced processes because it first, gave me an idea what it takes to brew, but secondly I was able to separate the simpler processes of steeping and know what I needed to perfect before moving on the partial mash myself.
Seeing the use of the mash tun and the temperature requirement was a bit intimidating. Certainly it was very difficult to hit a target temperature from a kettle to a mash tun. But our friend showed how he used BeerTools to calculate the temperature of the kettle with the distance in tubing from the kettle to the mash tun and the temperature of the grains, to get the mash tun the right temperature. Nevertheless, I happy to wait a while before I tried a mash tun on my own.
After hitting our target temperature, we got out the sparge and got a good grain bed to make some good wort. After boiling, doing the hop schedule and chilling, we popped it into the carboy and waited for fermentation. The original gravity came out on target, but the final gravity was a bit high. Our friend has a fermentation closet, and given this was December, his closet was in the low 60's. So we let the carboy sit for two weeks. We should be thankful that 2014 was a very mild winter or else the closet may have been better for a lager.
Even with the beer a little sweet, it turned out pretty good. Nice character and enjoyable. It left a good impression in my mind and my wife and I processed to purchase a starter kit from MoreBeer. With the kit came an Amber recipe, so my first brew recipe was set.
