March Haters Ale

Here in Central New York State the month of March can be kind of depressing. By that time we have dealt with many cold days, shoveling, scraping, fewer hours of daylight, and heating bills. The first day of spring is observed during March (my mother's birthday), but spring weather is still some weeks away.

In our family, it was Chloe that spoke up and voiced her dislike for the month of March. She didn't like the fact that there are no holidays or recess weeks off from school. "I hate March" she exclaimed, clinching her fists. The rest of us now echo her sentiment with similar fervor. We have started to think of ways to create our own holiday to make the month a little bit better. My own offering, for the over 21 crowd, will be this beer: March Haters Ale.

This beer is my first all-grain beer, which means that I milled my own grains (well, the kids helped a little) and mashed them to convert the starches into a sweet wort, as opposed to using a half gallon jug of pre-prepared malt extract. The recipe for this beer is Jamil Zainasheff's American Pale Ale recipe, which is published in the book, Brewing Classic Styles by Jamil Zainasheff and John Palmer.

On the day before (01-14-2012), I used a scale to measure the grains and a Corona grain mill to crush the grains. I milled the following grains:
  • 11.3 lbs (5125 grams) of pale two-row malt
  •  .75 lbs (340 grams) of Munich malt
  •  .75 lbs (340 grams) of Victory malt
  •  .5 lbs (226 grams) of wheat malt
25 pounds of pale two-row

I also prepared a yeast starter the night before. The recipe states that, if using liquid yeast, one should have either two packets of yeast or use one packet and make a starter. The goal is to have around 200 billion yeast cells. (I think I did; I lost count around 200,000. lol) I did the following steps to make a 1 liter starter:
  1. Smack the yeast smack pack (preferably an hour earlier and at room temperature)
  2. Clean and sterilize: glass container, sauce pan, spoon, funnel, yeast packet, tinfoil
  3.  Mix 4.2 cups (1000 ml) of water and 100 grams of DME in a sauce pan
  4.  Boil the wort for 15 minutes. Cover wort immediately after removing heat.
  5. Cool the wort in a cold water/ice bath to 70 degrees
  6. Pour wort into sanitized glass container, using a sanitized funnel
  7. Pitch yeast
  8.  Cover container with sanitized tinfoil
  9. Swirl mixture to aerate
  10. Place in warm, dark/dim area

Now that's a yeast starter!

I brought all my equipment in the basement up to the kitchen. I put my brew kettle on the electric stove and started measuring out my strike water, which is the first water added to the grain to begin starch conversion.

Strike Water Volume: 4.2 gallons
Strike Water Temperature: 165 F
Target Mash Temperature: 152 F
Actual Mash Temperature: 150 F ?
Mash Time: 60 minutes

I used an iPhone app, Sparge Pal, to determine my strike water amount and temperature. However, I guessed the temperature of the grain, which may have caused my recommended strike temperature to be low. My target mash temperature, as stated in the recipe, was 152 degrees.

Note: When using software to determine the strike water temperature, take time to check the temperature of the grain (a typical variable for such a calculation).

I pre-heated my mash tun by adding a half gallon of hot water and closing the lid. This may or may not be a sufficient means to warm a mash tun.

After I poured the strike water into the mash tun (at 12:10 pm), I stirred the grains. The grains came nearly up to the top. I put my thermometer in and got 150F. Mind you, my thermometer is analogue and is not precise. Also, my thermometer probe was only a few inches into the grain. I decided to heat a couple cups of water and try to raise the temperature. Even though I had the lid closed on the mash tun, I got 140 F after I added the extra water. I started to freak a little at this point. There was little room left for additional water. I warmed more water to 180 F and added that. I was still only reading about 140 F. I couldn't add any more water. I decided to just close the lid and let it rest. I figured my original water was close to the target temperature and hopefully most of the grain, further down, was fine.

Note: Regardless of calculated strike water volume, make sure there is enough room in the mash tun to add water in case the temperature needs to be adjusted.
When I closed the lid on the mash tun, some water (sticky, brown mash water now) came out on the floor. Also, while stirring the grain, some of the grain splatted on the floor--looks like soupy oatmeal. I decided that in the future I should have a tray underneath the mash tun when pouring water and stirring.

Note: For the sake of cleanliness, have a tray under the mash tun when adding water or stirring grain.

After 60 minutes, I started the vorlauf (at 1:10 pm), which consists of draining the caramel liquid from the mash tun into a clear plastic pitcher, then pouring it back into the mash tun. The idea is to cycle the liquid a couple times until it is free of small grain particles. Once the liquid is running clear, it is drained into the brew kettle. This is called, "first runnings."

In the meantime, I had heated 3 gallons of sparge water to 150 degrees. I poured the water into the mash tun, but not all of it would fit.

Sparge #1
Sparge Water Volume: about 2 gallons
Sparge Water Temperature: 150 F
Mash Time: 20 minutes (1:18 - 1:38 pm)

After 20 minutes I emptied the liquid into the brew kettle. There was still not enough wort collected so I heated more water and poured another 2 gallons or so into the mash tun. This may be typical for a 5 gallon mash tun and so much grain (13.3 lbs).

Sparge #2
Sparge Water Volume: about 2 gallons
Sparge Water Temperature: 150 F
Mash Time: 20 minutes (2:00 - 2:20 pm)

After I emptied the liquid from the second mash, I took a sample of the wort to get my pre-boil gravity (once the sample liquid cooled to 60 degrees in the refrigerator).

Pre-Boil Gravity: 1.062
Pre-Boil Volume: about 7 gallons

The recipe expects a pre-boil gravity of 1.048. My reading was high. I'm not sure what accounts for it. Maybe I just got wicked amazing starch conversion. That reading prompted me to test my hydrometer by putting it in tap water. I got a 1.000, which is correct, I believe.

I started heating my wort to begin a 60 minute boil time and hop additions (at 2:30 pm). I use the Clock app on my iPhone as my 60 minute timer. I used my new scale to weigh the hops.

Boil Time: 60 minutes (starting at 3:14 pm)
Music: This is Happening by LCD Soundsystem

Hop Additions
  • .66 oz (18 grams) Horizon @ 60 min
  • .5 oz (14 grams) Centennial @ 10 min
  • .5 oz (14 grams)  Cascade @ 10 min
  • .5 oz (14 grams) Centennial @ 0 min
  • .5 oz (14 grams) Cascade @ 0 min
  • 1 oz Amarillo dry hop 1 week before bottling
(I'll also add the leftover Horizon hops when I dry hop.)

After I added the last of the hops, I turned off the burner, put on my (new) oven mitts, and carried the lidded brew kettle down to the utility sink in the laundry room.

To use the immersion wort chiller I need garden hose threads to attach to the faucet. I tried to find an adapter to fit our kitchen faucet so that I would not have to carry the hot kettle down a flight of stairs, but I was unable to find one.

Usually, brewers put their wort chiller into their wort during the last 15 minutes of the boil to sterilize. But because I knew I had to carry the hot kettle downstairs, and I wanted the lid shut tight on the kettle (no hoses sticking out), I did not put the chiller into the wort. Instead, I had the chiller submerged in a StarSan and water mixture.

Once downstairs, I submerged the wort chiller, attached the hose to the faucet, then started running the cold water (at 4:15 pm).

After the wort was cooled to 70 degrees, I carried the wort back upstairs and poured it into the (sanitized) fermentation bucket. I took my original gravity reading and pitched the yeast (at 4:42 pm).

Original Gravity: 1.060

The recipe calls for an OG of 1.056, so I wasn't too far off. The wort tasted sweet....and bitter when I got some of the zero minute hop sediment.

I ended with 5.5. gallons of wort in the bucket, which is exactly what I was aiming for, as per the recipe.

Fermentation Temperature: 65 F

Because of my brilliant yeast starter, the stopper was bubbling away within five hours.

Grain: $11.14
Hops: $6.78
Yeast: $6.25
Other: $7.99 for shipping
Total: $32.17

I used an All Grain Recipe Template and All Grain Brewing Checklist from Brewer's Friend. They came in handy; I may use them next time. I'll use the Brewhouse Efficiency Calculator later.
