It's based on the Tricentennial recipe from JZ's "Brewing classic styles" book, however mine has a slightly higher OG due to higher than expected efficiency. My FG was lower than his but so was my bitterness so the bitter/sweet balance should be similar.
The fermentation on this was explosive, I had 5 liters of head space in the FV and still ended up with about 2 liters of beer all over the floor after less than 24 hours!
It was named by a friend who poured a glass and held it up to a light to check clarity, but found that it is so dark it simply absorbs all light
