IIPA Recipe Feedback

[rivertranced]

Looking to create a hearty, full-bodied IPA with a good percentage of late addition hops to pack a nice aroma. Thinking of the DFH 120 style in terms of body, though not that big (don't want it to be chewy). This one will fall right between the IPA/IIPA style guidelines.

Any feedback, on the malt bill especially?

Looks good. Might want to stack up even more on the late hops though given what your goal is. Maybe 2 oz. at 10 min., another 1 oz. at flameout, and another 1 oz. at dry hop.

What are you looking for in terms of malt presence other than fuller body? The higher mash temp and cara- malts should help you with body. You could even substitute some flaked oats like Surly Abrasive does.

You're mashing at the ratio of 1 lb. grain to 1.75 quarts water, correct? I'd go lower, but that's me.

Are you making a yeast starter with the WLP001?

What's with the "Dry Hop 0.0 Days" for Citra?

Thanks for the feedback. I was considering adding a little more late addition hops...I think I'll do that.

I'd like a little sweetness in the malt as well, which I think the crystal and munich will help with. I was debating whether it's necessary to have this many malts (I usually go for a simpler malt profile), but I think each one I have here brings its own benefit and might add a little complexity.

I like the idea of the flaked oats. Would you sub out the cara-pils for this?

My mashes have been pretty thin. The reason for this is I batch sparge, and I'm shooting to get a 1:1 lauter:sparge ratio where possible. I've not had any issues with efficiency (in fact, my mash efficiencies have been in the mid 80s). Is there any other reason to go thicker?

The Dry Hop for 0 was my error - I didn't add length to that one. I typically dry hop for around 7 days.
