Notes

10g of S04 yeast.
Lower than expected OG of 1.050. Same amount of yeast, so possible over-attenuation issue. Also, added sugar to to boil which may account for efficiency problem i.e off target OG.

Second brew:
New equipment and much bigger volume. Pre-boil gravity 1.047, very near target. OG at 61c (adjusted for temp) was 1.053, so a few points off. Not sure why though... Will test again prior to pitching when temp comes down. Trialling no-chill in the primary fermenter.

Chilled in the kettle outside to 68c then transferred to fermenters and left outside. Brought in overnight and by morning down to 18c! Yeast pitched. It is Autumn now, so that is why the overnight temps are cool enough.

Very vigorous fermentation with little headspace in the fermentor led to stout all over the place and replaced the sanitiser solution in the airlock. Successful test run for my fermentation chamber.

Gravity at 10 days 1.014. I think it is done, but will leave for another three days and test again. Gravity at 12 days 1.013. Cacao nibs and drops of Orange essence into the primary of one fermenter. The other will be left as a staright Oatmeal stout with a big chunk of chocolate malt.

This is a very decent stout. It's now been bottle conditioning for a couple of months. Will brew this again. Possibly cocoa powder into the boil next time for chocolate punch. Orange also barely noticeable, will need a much bigger dose next time.
