Notes

2017 version had all kinds of malts in there: c20, c120, brown, chocolate, black barley (pic)
2018 I'm simplifying and just using brown, c120 and black barley

  • expect terrible efficiency in the 55% range. There's just so much grain to mash. Maybe try leaving it overnight next time for some extra grav points and better fermentability.
  • Last time was 10kg of base malt for 24L. Mashed 1hr and got 1.078 pre-boil.
  • added 500g sugar to get us up over 1.085; shooting for around 9% ABV
  • Experimenting with adding 1/2 Bourbon-soaked oak spiral (and some of the oaked bourbon) to the keg.
  • bumped up the black barley (+100g) as this one (2018) is a bit light once it clears.
