I been correcting some of my to-be-brewed-recipes since I learned about the bitterness ratio not too long ago. One of my recipes was way out of chart and I had to look at the original recipe to see where I typed wrong, but it seems like I hadn't. I did scale the recipe slightly, the original was for 19 litres and I got it down to 10 litres, which is the amount I've been brewing so far since it fits me well. I scaled the hops accordingly of course.
However, the IBU is at 112 (the original says 108), giving it a BU:GU ratio of 1.73...which would make it very bitter if I've understand things correctly?
I've been looking at this chart http://www.bullcityhomebrew.com/images/Bitterness-Ratio.pdf and the top value in that chart is a imperial IPA coming in at a max ratio at 1.33. So my question, is it something wrong with the original recipe or could some beers actually have those high IBU:s?
