Instead of following suit, I found myself formulating a recipe for a special bitter pale ale and got to brewing this past Sunday afternoon. The high pressure propane burner warmed my feet as it melted the ice and snow away from underneath the stand. This was my first wintry brewing experience, although I did enjoy a weather-ridden brew with Matt when the sky opened up during our Rainy Day IPA this past fall. In my opinion, a bit of chill in the air beats being soaked by a cool fall rain.
Using Designing Great Beers as my guide, I put together a rather simple recipe. Here are the details:
U.S. Pale 2-Row: 8 pound (85% gravity contribution)
U.S. Crystal 40L: 1 pound (10%)
Belgian Carapils: 0.5 pounds (5%)
Cascade Bitter hops (60 min boil): 1.5 ounces
Willamette Flavor hops (5 min): 0.5 ounces
Willamette Aroma hops (2 min): 0.5 ounces
White Labs London Ale (013), liquid yeast
IBU: ~40
Target gravity units: 41
Target conversion efficiency: 60%
Previous conversion rates had been pretty low with our all grains brews. I wanted to be on the safe side this time around so I calculated the weights using a 60% efficiency. This was also only the 2nd time attempting the batch sparging method (versus fly sparging in the past), and it was quite obvious that this time around I did something right...
OG: 1.046
Actual conversion efficiency: 68% - not too shabby
My liquid yeast starter wasn't fully active, and I had recently read a blog post by Ben's Homebrewer of Tarentum who described a time-saving method of pouring the wort into the carboy at around 160F and allowing it to cool overnight; so I decided to try this practice out. Proper sanitation combined with the pasteurizing temperature should leave the carboy in a bacteria-free state, and time is saved not worrying about driving the temperature down to a yeast-friendly 70-80 degrees F.
To bring the temp down from boiling to the low 160's, I took advantage of the snow in my backyard:
So far this method seems to have worked perfectly. I poured the starter into the carboy this morning and upon my arrival home at the end of the work day, I was greeted with a popping airlock and a foamy headed vessel of brew.
Here's hoping it's a tasty one!
