oatmeal stout went primo. no sticking at all, i was shocked. evidently a 4 hour mash allows plenty of time for the enzymes to do the job. took the sparge slowly and it flowed out real nice, and left a quite impressive layer of protein/gloopy material on top of the grain bed at the end. waaay overshot the gravity (1046 recipe predicted; 1055 actual) but rather than water it down, just left it and decided a stronger stout would be just the ticket for mid-winter. fermenting nicely this morning. am a happy bunny.
well it was only an improvement over what the recipe predicted; i always thought the recipe looked a little big for the predicted OG. for a total grain bill including oats of 4.75kg, 1055 is absolutely normal for me (between 11 and 12 gravity points per kilo. since all my brews are 20L that's how i calculate my overall efficiency, since it is easier than points per pound per gallon or whatever the yanks use).
What a comedy of errors! I woke ready to start brewing, the sun was shining, it was my birthday, a fresh packet of hops waiting.....
I tend to be an anti-perfectionist generally speaking and my brewhouse practice is no exception to this rule. I usually have to be satisified with an efficiency of between 50-55%. Not sure why, although i'm beginning to suspect the number of uncrushed grains in my malt may be the culprit. I had a rare stuck sparge today, nightmare. It took me quite a while to correct and as a result the sparge took double the time it usually does. After the sparge I checked the gravity, and I'd overshot my recipe by a mile from 1.052 to 1.064.
Ah well, I thought, I could just dilute it back. Following the boil, I set up my copper coil chiller into the wort and left it to its work, I came back about 20mins later to find the hose had slipped off and was merrily splashing into the wort. I caught it before it was ruined but I'd added about 4 litres of water into the wort...... I thought I'd blown it, and maybe I have. But the dilution gave me an OG of a respectable 1.050, Swings and roundabouts.

Fermenter is sat in the garage which is showing a steady temperature of around 16 degrees - bit borderline but as long as it kicks off strongly it should be OK.
