This brew is a very special one for a couple reasons. First, I started around 11:00am on Sunday, and so didn’t down a single beer during the process until the boil, around 2:00pm, and had only one beer throughout the whole process. In other words, I was much more sober than usual. And wow, was the brewing process much smoother. I suspect I’d begun to take “Relax, Don’t Worry, Have a Homebrew” a little too much to heart, particularly that last clause.
The other reason this brew was special was my first ever use of a yeast starter. Which kicks ass! I’m very stoked that I did this, as it wasn’t all that much work and I ended up with a lag time of less than three hours(!!!), as far as I could tell (we went to Barclay’s Oktoberfest celebration directly after pitching the yeast at 5:00pm, and by the time we got back at 8:00pm, the bubbles were bubbling through the airlock).
I don’t know how starters should be done to be safe and professional about it, but I used info from Dave Miller’s Homebrewing Guide. I didn’t quite do it to his specs, but I will probably eventually try his method (which involves a canner or pressure cooker to sterilize several bottles of wort, to be stored and used as necessary).
Yeast starter method
On Saturday, about 20 hours before I needed a starter, I boiled 3 quarts of filtered tapwater and added enough DME to make a wort of SG 1.025. I was aiming for a final volume of two quarts with a volume of 1.025. I cooled the wort down to 72 degrees Farenheit with an ice bath in the kitchen sink (my usual cooldown method - much easier with 1/2 gallon of wort). I ended up with about three quarts of wort at 1.025, so a bit more volume than I was hoping for. After cooling down the wort, I poured it into a gallon jug, covered it in foil, and shook it for five minutes to aerate the wort. I thought I’d be able to fit an airlock onto the jug, as I have stoppers for large carboys and small bottles. Turns out, I don’t have stoppers for gallon jugs, dammit. So after aerating the wort, I shook up the yeast (which had been sitting out of the refrigerator for about an hour), and dumped it into the jug. Unfortunately, I didn’t shake the yeast enough and I ended up with a bit of sludge still in the beaker. I covered the jug with fresh foil, shook it gently to remove some yeast that had stuck to the side of the jug, recovered the jug with more fresh foil, and placed it on the living room table for observation. Bubbles were observed around 12:00am 10/7/7.
Mash-out
One other minor bit of novelty in this brew was the mash-out, which I haven’t done before. Miller claims mashing out (raising the temperature of the mash from 15x to 165 or so after conversion is done and holding that for 15 minutes) kills the enzymes responsible for conversion and makes the wort less viscous. I forget why the first bit is important. The less viscous bit is for an easier runoff without as much danger of clogging. I just figured I’d give it a go.
I also used my 20 quart kettle for mashing, rather than mashing in a plastic bucket with a spigot. So I had separate mash and lauter tuns for this brew. It’s my third mini-mash, and the first where I mashed in the kettle. I’ve had problems with rapidly dropping mash temperature in the past, so I wanted to be able to easily heat the mash if necessary. In the end, it wasn’t necessary, though it would have been in the plastic bucket.
Sparge
Sparging only took about 35 minutes, 10 less than recommended, but by the time it was done, I had so much wort (~4 gallons at 1.049) that I had to take out a quart for the first hop addition, after I’d added the five pounds of extract and started the boil. I slowly added that extra quart of wort back in as the boil went on. I’m thinking of drawing five gallons of wort in the future, and giving that extra gallon a separate boil, so I can at least add wort instead of water to make up the five gallons in the fermenter. That, or just buying a new, 7.5 gallon kettle for a full boil.
Cooling
The final step, cooling, is my least favorite. As mentioned earlier, I use an ice bath in my kitchen sink, and cooling down 4.25 gallons of wort takes 30 to 45 minutes and is a bit nerve-wracking. I used two bags of ice, added in half-bag increments. First, I’d pour some ice into the water surrounding the kettle, then stir briskly with a sanitized plastic spoon for 10 to 15 seconds, then cover the kettle and start stirring the cold water around the kettle by hand. After I got bored with that, I’d open the kettle up, take the temperature, and start stirring again. Etc., etc.. I fucking hate cooling down the wort. Next on my to-purchase list - an immersion cooler.
As usual, I didn’t quite cool the wort down as much as I should have (I cooled it down to about 95 degrees), so even though I added two quarts of cold, filtered tapwater, and then added in three quarts of 70 degree yeast starter, the final temperature of the wort was about 78 degrees - a little too high. Also, that three quarts at the end knocked the volume up to about five and a half or five and a quarter gallons, and knocked the gravity down a bit (I think - not sure since I didn’t take a pre-yeast sample), to 1.065.
Fermentation
Fermentation started, as I said, within a few hours. It went completely nuts for about 36 hours, remaining at about 76 degrees despite being in a cool, dark room (the sweet heat of gorging yeast). The fermenting room (aka the computer room) and the hall leading to it smelled like fermenting beer, there was so much gas being released. As of the third morning, the bubbles were down to one every second or so, and the yeast was starting to flocculate and settle, though there was still a decent crust. By the fourth morning, most of the yeast cake was gone from the top, there was an inch or two of sediment on the bottom, and the airlock was bubbling about once every 30 seconds.
Funk
One worry about this beer - it has a distinct hop funk smell and some funk flavor, as well. This isn’t an off flavor, really, it’s the way certain strains of hops taste to me. I’m never sure which they are, though. On a positive note, this kind of funk goes away over time, and since this IPA will be around 7% ABV, it should age well for several months, maybe even a year.
