I was trying to get the most out of the CTZ, but that’s also why I posted to see others opinions and gain some more knowledge.
There's so little increase in hop utilization between 60 and 90 min. that I consider it negligible.
Re: Pinski's advice....if you do that, it will leave you without a 60 min, addition. although I FWH a majority of the beers I do, I still use a 60 min, addition for bitterness. For me, I don't get enough "sharp" bitterness with FWH only, especially in an IPA. Here's what I'd do...
1oz Warrior FWH
1oz CTZ 60min
1oz Amarillo 10min
1oz Simcoe 5 min
1oz Citra 0min
Be sure to recalculate the IBU fpr the recipe to be sure you're getting the right amount for your IPA.
