Batch Size: 6 gal
Boil Time: 60 min
Final Bottling Vol: 5 gal

Notes:
Final Gravity on the refractometer was about 8 points higher than the hydrometer, I adjusted the refractometer (I’ve done this a number of times now, starting to think you cannot rely on the refractometer, at least the one I have).
I didn’t have the gas on when I hooked up the c02 ball lock and beer shot up in the gas hose, so I had to clean it out. Looks like it helps to have the gas on to equalize any pressure that may have built up in the keg, or vent the keg first before hooking up the gas line.

both dry hop addionts (keg and primary fermentation ones) were the 75+35g?
Yup, all in the keg post-fermentation. I’d probably consider doubling the dry-hop addition now though.
