I only got about 35L.
36IBU, 7.2EBC 4.6%. I recommend giving it ago.
A few things not right with your numbers, at 35L it puts it around 6.3% ABV (based on 73% efficiency). Additionally, your flameout addition of Citra says it contributes 0 IBUs.. that's not right either unless it's an aroma steep below 80 degrees, even then I'm still getting around mid 50 IBUs with those amounts based on 45L into the fermenter.
Anyway, I've juggled things around and threw a touch of light crystal in there, do you think this will be alright/close..?
