Water is incorrect. I can't save it as total 64L of water. 34 mash and 30 spare. It records it as total water of 34 which puts the above overall water report out.

Notes

Attempting a smooth chocolate and coffee stout using Cacoa nibs and coffee, likely add to the late fermentation. Lightly roast the Cacoa nibs. Considering soaking the Cacoa in Vodka for a week and adding the liquid to the fermenter towards end of fermentation.

Adding both chocolate malt and the roasted barley in last 10 mins of mash after cold steep overnight in 4.2L of treated water from the mash volume. Used a sieve to separate the dark drains from the malt. Added the thick dark liquid down the side of the grain basket into wort during early sparge. Added the grains to top of grain basket and sparged with the cooler sparse water 65C. 30L sparge water used.

Adding 1kg of sugar to the boil to replace lost sugars in the higher temp mash 68c Aiming for about 5.6 to 6% ABV. Also added 1kg lactose to sweeten the brew to accompany Chocolate and Cocoa.

Very sticky slow mash. Not sure why as there wasn't much stuff got out of the grain basket.

Achieved 52L in fermenter at 1064 which is 75% efficiency.
