All ingredients several years old.  Closet-emptying brew. \\
 \\
60g earl grey ("Countess Grey"), steeped in 500ml cold water in french press overnight.  Entire thing, leaves and all, to pitch in at flame-out for sterilization. \\
 \\
Used extra rice hulls: ~500g \\
Started with a layer of rice hulls, then grain, then a layer of hulls, then rest of grain. \\
Maintained constant recirculation flow during mash, but only on extremely low flow.  It will be slow to drain. \\
Nope, actually sparged just fine. \\
Forgot to check first-runnings volume.  Seems a few liters lower than calculated. \\
0.5 tsp protofloc + 1.5 tsp yeast nutrient @ 10 mins \\

==== Brewday Analysis: ====

Everything went swimmingly. \\
A tiny bit low on predicted volume and a smaller bit high on OG. \\
pH and refractometer readings really made no sense.  pH meter might need new calibration liquid, or a new sensor.  Or else this dark beer is much more basic than the earlier light beers... \\
Ludicrous quantity of dense foam in the fermenter.  Had to stir it down with a spoon to get the yeast into liquid. \\

==== Calculated Recipe Adjustments: ====

Real grain absorption: 1.470 \\
Real efficiency: 67% \\
 \\
Volumes match perfectly when grain absorption rate is changed.

==== Fermentation Notes: ====

Bubbling after 12 hours.  48 hours of vigorous, slowed down for third day. \\
2021-01-23: FG 1.022 (much higher than expected), tastes good.  Porter-ish, with hints of bergamot. \\

==== Bottling Notes: ====

Put on balcony to cold crash before bottling. 24h, dropped to 7°C. \\
Added 138g table sugar to bottling bucket.  Racked and kegged while cold. \\
Volume at bottling: 25L \\
Exactly 5 kegs (4.9kg each), zero bottles. \\
