Notes (Include any important notes from brew day until tasting)

Very happy with actual boil. 6 hours: Fermentation active. Temp started at 75/76F. Reduced to 72 with wet tea towel. 1 day: Blew lid off 6.5gallon fermenter. Very very active. Using a blow-off tube into jar of Star-San. Temp still at around 73/74F. Aiming for 68F but not getting there. House ambient is 71F. Got regular airlock back on 8 hours later (9pm). Temp at 72/73F. 2 day: yeast cake dramatically smaller. Down to 1/2 inch. Still bubbling, but more slowly. Temp down to 70F.

Gravity Estimates

Based on boiling 6.50 gallonsliters at 1.046 for 60 minutes, this will decrease your wort by 0.00 gallonsliters, bringing your after boil OG to 1.046.

You wanted an OG of 1.052. It looks like it will be under.

Tasting Notes (1)

Tasted on 3/30/2016 by Apprentice-Brewer-US-GA

Notes:

Sweet. Not surprsing given the low attenuation and consequent higher than predicted FG. ABV dropped from a predicted 5.1% to 4.7%. No depth to flavor; more of a single flavor note. Might change with more time. Perhaps should have left in fermenter another week as well (was only 3 weeks total). Low carbonation (again). However, it was only chilled from 70F to 40F in the bottle for a few hours. Probably needs a good 3 to 4 days of chilling to get CO2 into the beer more effectively. Also need to work on head retention.
