At the back of the IPA book by Mitch Steele he lists a number of recipes and the hop bill for most of the recipes he lists as percentages. I’m not too sure what this means. Percentage of what? Is this percentages of the total IBU’s of the beer?
If its percentages of IBU does it take into consideration the lower IBU contribution of later hop additions? if so since 0 min additions theoretically add almost no IBU’s this doesnt make a whole lot of sense.
