yeah i always mix it well.
i think i figured out the problem this morning while laying in bed. this is my big IPA, and the last time i brewed it i noted i needed to increase the batch size because the hops soaked up a lot of wort. i didn't acount for the amounted soaked up, so basically i thought i hit my final volumn with the boil off, but really i just didnt boil off enough.
