Looks good! What are you replacing the simcoe with?
The closest hop AA%-wise was chinook. Rather than double up on that, I decided to go out on a limb and try other hops that I've meant to try for a while: Amarillo and Northern Brewer. My reasoning was that I can use more of these hops than what was called for with simcoe and hopefully come out close. I'm not too worried, should I be? What would you guys have used instead??
Here's the measured hops for the 30 min addition. I've managed to muck up the timing of the hop additions so far. I'm keeping track of what I'm changing though and I'll post the results at the end.
