Brewday Notes:

First brew on induction stove.
Strike hit 67C according to one thermometer. Two thermometers, two values. Yay.
Mash extract was too good: 6L from bag, batch sparged in 4L and topped up to 10L. Boil SG 1.082
Boiled at stove #8 (biggest burner), partially covered. Good rolling boil.
1 tsp fermaid, 1 tsp floc @ 10min remain.
Added 3L cold water to boil at flame-out – to prove it fits. Up to 2L more in boil would work if very, very careful with DME. 3L leaves no head space for DME foam.
Exactly 10L post-boil (13L post top-up). Added another 12L cold tap to 25L @ 34C.
OG 1.068. Why is it a bit low after super efficient extract? Damn it.
Added 2kg boiled blood oranges in muslin bag to fermenter.
Yeast starter: smack pack in oven at 35C for 2 hours until inflated, then mixed with 250ml/25g DME in oven at 35C for 2 hours, then left on counter for 4 hours until frothy. Split between Icelidae and Nociception.
OG 1.072 @ 24C, on target. Must not have been mixed well for previous reading.
Shook bucket for 3 minutes.
Mild bubbles at 12 hours, strong bubbles at 24 hours.
Bodacious bubbles at 36 hours, calmed to frequent bubbles at 48 hours.
Bubbled firmly for ~14 days. Kept bubbling slowly for 30 days. Removed orange bag to see if it stops (2017-03-19)
SG @ 2017-03-19: 1.018 (ABV: 7.1%)

Left for over 1 year. Airlock dried out.
FG: 1.012 (ABV: 7.9%)
Uncarbed tasted like a low-hop pale ale with a nice sour cherry hint.
Bottled 21L with 110g table sugar (~4.2L of trub)
Only 18L ended up in glass.

2018-06-24: Didn't carbonate after 3 months, so moved back to bucket to retry. Turns out it was carbed by then, and SG measured 1.012. Interesting that it was flat and uncarbed for literally months, then suddenly carbed up. Taste is very malty, no hops left. Reminds me of a Belgian Strong Ale. Rebottled 15L of carbonated beer in 5L mini-kegs. Added 40g (total guess) table sugar to replace the CO2 lost in the bucket, and pitched packet of Safale S-33 hydrated in a 20g/200ml DME starter for a few hours (starter was highly active and gassing). Scale only goes up to 4.5kg, so weighed kegs up to that and added another ~10s from the bottling wand, leaving 2-3cm headspace.
