Brew Day Complete

A little under on volume--a little over on gravity. Pressurized to 14PSI and adjusted the spunding valve to 12PSI. So fucking cool! The spunding valve is set to release gas like a blow-off tube. We shall see. So fucking cool!

Packaged

Pressure transferred to keg. Added gelatin. Forgot to cold crash after diacetyl rest but things were already in motion. Added gelatin to keg and purged the keg with co2. Transferred beer to the keg. From fermentation chamber to kegerator--fucking awesome!
