IPA Hop Schedule Noob Question

I'm preparing to brew my first batch of homebrew and seeing that I'm a big fan of IPA's I wanted to try that first. I really like the hoppy/citrus flavor and aroma of Bell's Two Hearted and found a clone recipe that I want to give a go.

One thing I don't really understand is the hop schedule. Can someone explain this to me or direct me to where I can find the info? In particular, I'm talking about this one that I found in a Two Hearted clone thread...

Hop Schedule:
1 oz. - Centennial (60 min.)
1 oz. - Centennial (15 min.)
1 oz. - Centennial (flameout)
1 oz. - Centennial (Dry Hop)

Also, if there is anything else I might need to know about brewing an IPA, don't hesitate to let me have it.

 

Generally, the 60 min addition is purely bittering, around 20-10 is for flavor, and anything after that is aroma. If you want something with a big hop punch I would maybe even add a 5 min addition of 1 oz. I tend to really load up the end of my IPA hop schedule. It wouldn't really add any bitterness anyway, but just gives a bigger aroma.

 

I guess mainly what I don't understand is the timing. Based on the schedule I posted, would I add hops 60mins into steeping, then another addition 15mins after that and so on?

Sorry, I said it was a noob question and I'm about as green as they come.

 

i'll just add that the longer the hops are boiled, the more isomerized alpha acids (bittering stuffs) get into the beer, so that's why the longer you boil the hops, the more bitterness you get from them. hops vary in the amount of potential bitterness they have (alpha acid %), centennial is moderate, but there are hops with more bittering potential. it's a great hop all around. that schedule should get you close to a 2-hearted clone.

 

the timing refers to how long they are boiled. 60 = in for the whole 60 minute boil. 30 = with 30 minutes remaining in the boil, and so on.

and this all happens after steeping.

 

What those times indicate is the length of time that you will BOIL the wort AFTER you have added them. So you start your boil add your hops and set your timer for 60 min. When the timer counts down 15 you add the 15 min addition, etc., etc.

 

The 60 minute addition is added when the wort starts boiling. The 15 minute addition is added with 15 minutes left in the boil.

 

Thanks for the info and quick replies! I'm using the iPhone app and the search function isn't the greatest so I appreciate the patience with my greenhorn questions.
