Hi,
I'm brewing a Brewers Best Australian IPA extract kit. The kit instructions indicate an IBU of 64-68. I put the recipe into iBrewmaster and it calculates an IBU of just over 31. I'm wondering if I maybe entered the recipe wrong? Or the software calculated incorrectly? Recipe follows, as entered in iBrewmaster.
