The first one is in a corny keg so I can test it in a few weeks.
I only ended up with 14l in the racking bucket so for this one I've increased the boil volume to give me a ful 23l in the primary rather than 19l
I increased the grain and hops to compensate and I added 350g black malt instead of 150g along with 250g chocolate instead of 150 to make it darker.
I ended up with 25l post boil instead of the target 23l (Still need to dial in accurate figures) so my target OG is down a little but I'm not too worried about that.
I've kept some of the spent grain to make some goblin bread
