Mash went great with new PID, and new grist ratio @ 4l per kg. Really ran smoothly with good throughput and nowhere near a stuck mash. Downside, perhaps, is a much smaller batch sparge vol (12l) but mash efficiency was actually OK @ 80%. I had issues with water volumes that I have described elsewhere, and ended up with 33l instead of 31 in the boil.Recipe Specifications

Notes:
------
Water vol issues meant a higher volume at the end as well (about 27l) and correspondingly lower SG @ 1.055. Never mind - I did consider adding some DME but decided against it, as the beer should still be fine. Perhaps even more drinkable at mid 5's % than nudging 7 (after bottling).
Couple of obligatory shots, boil:

Cold break forming:

One bummer is that I managed to leave an airlock (bubbler) in the fermentor when I filled it (had been sanitising it and left in there until required). I *think* it should be pretty sanitary. Let's hope so..
Pitched a 1.8l starter of WLP090 (San Diego super yeast) to 18C wort. First time with this one, quite excited to see what its like.
