 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. \\
+.5 tsp protofloc + 1.5 tsp yeast nutrient @ 10 mins \\
+==== Brewday Analysis: ====
-==== Fermentation Notes: ====
+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: ====
-==== Bottling Notes: ====
+Real grain absorption: 1.470 \\
+Real efficiency: 67% \\
+ \\
+Volumes match perfectly when grain absorption rate is changed.
+==== Fermentation Notes: ====
-==== Brewday Analysis: ====
+Bubbling after 12 hours.  48 hours of vigorous, slowed down for third day. \\
+-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. \\
