Success! My experiment with summer brewing (using a temperature-controlled freezer) has gone well, so last night I bottled my summer blonde ale. Here are the stats:
- I fermented it from June 28 to July 7 at 62°. I didn’t see quite as much krausen as I’m used to, but I suspect that is because of the lower temperatures and thus a less vigorous fermentation.
- On July 7, I raised the temperature to 64°, so that the yeast could clean up any stray diacetyl.
- I bottled on July 12. Final gravity was 1.008, down from a starting gravity of 1.046. This works out to 5.0% abv, and an apparent attenuation of 82% (right in line with the expectations for the yeast, Safale-05).
- I kegged 5 L in a mini-keg, with 1.5 tbs. of corn sugar.
- The remainder (3.75 gallons) was bottled. I wanted a target carbonation of 2.5 volumes, which worked out to 3.1 oz. of corn sugar boiled in 2 cups of water.
- Bottling yield was 22 12-oz, 6 18-oz Grolsch, and 4 22-oz. bottles.
The flavor was somewhat malty with a touch of hops bitterness (but not overly bitter). No off flavors were detected, thankfully. The beer is hazy in appearance, but not overly so. I expect this will settle out during conditioning and refrigeration.
