Cocoa Nibs and Coffee in 5 gal for 10 days

Divide into 3 fermenters for final week

more cocoa nibs 3.5 gal
coconut 1 gal - 
cherry 1 gal - 

Brewing notes:
Mash temp was a little low at 143 so added a gallon of boiling water to raise it to 153. (if brewing in cold weather, start mash water temp at 180 deg.)
Used 5 gal mash water and 5 gal sparge water.  Probably only needed 4 gal sparge water.
Mash got stuck so had to take out of mash tun, clear issue and replace back into mash tun.
Collected too much wort.  One gallon extra. ooops.

Alcohol estimated at 8.9% from all grain ABV calculator

Original Gravity
(These taken preboil, so will be inaccurate)
brix - 20.5
Potential Alcohol - 11%
Sp. Gravity - 84

Rack base beer into all 3 fermenters
Add cocoa (2 oz) and coffee (3 oz) to 3.5 gallon for 10 days

One gallon Cherry version
Add cocoa (0.5 oz) and cherries (8 oz)to 1 gallon for 10 days (small mouth jug)used a bag of TJ's tart cherries.  Way too much cherry and sugar (bottles overcarbed) - reduce to 1/3 bag.

One gallon coconut version
Add cocoa (0.5 oz) and toasted coconut (3.5 oz) to 1 gallon for 10 days (large mouth jug) toasted the coconut in the oven, but used too much, regardless, it was quite good.

Removed cocoa and coffee in 3.5 gal batch after 4 days for fear of it getting too bitter.  Added 1 oz cocoa nibs to replace.



The regular version did not carb up well (neither did the coconut version)
On March 23, 2020 I dumped all regular version bottles and 3.5 bottle of cherry version into keg and carbonated.  This mixture turned out very good, with a nice cherry chocolate flavor.  Toned down the cherry flavor.

Use less cocoa nibs to reduce bitterness
