Newbie 90 min IPA clone question

I've only made 2 extract batches from kits (Belgian Ale and Honey Brown Ale), which both have turned out fine. For my 3rd I wanted to make an IPA and found the clone for partial mash 90 min Dog IPA.

I messed around with Beer Smith and just tried to get the OG, FG, and color to the partial mash using LME and DME and kept the hops the same.

Below is the recipe I came up with and my basic question is even if this doesn't turn out close the the 90 Min Dog IPA, does this look like a do able recipe. I'm still learning the ropes.

I will be doing a partial boil of about 3 - 3 1/2 gallons in a 5 gallon stock pot.

I believe the bitterness at 62.4 IBU is probably not what it will end up being since Beer Smith is figuring on a 90 min boil.

Just wanted some thoughts before I go out and spend 50 bucks on a recipe.

Why not boil the hops for the entire 90 minutes, hop schedule still shows 60? It would increase your bitterness alittle, if that's what you want.

Or maybe you are, you can change the boil time in beersmith for the individual ingredients. You could even add in every different timed addition for every .2 oz, but that would be tedious.

Also, with that much malt, you may consider doing a late addition with some (if not most) to avoid over carmelizing the brew.

Other than that, looks good. Don't forget to make a good starter for that yeast. Happy brewing.

doh, forgot to change the hops to the full 90 minutes. And yes, putting in each .2oz addition is going to be too tedious for me.

This is the 1st I've heard of doing a late addition of malt, I'll have to read into that and follow your recommendations.

Thanks for the info.
