Personally, if I subbed out Cascade for Citra, it wouldn’t be oz for oz. Citra is a great hop but can flat take over if used in equal amounts with other hops IMO. I would use 1/2 (or just over) the amount that you used for Cascade. I’m sure it would work either way though.
I’m thinking about trying to bitter with Summit and finishing with Simcoe and Mosaic. I’ve read a lot of threads where people knock Summit, and the profile taste of “garlic/onion” is kind of a turn off. I just had an Oskar Blues Gubna, which is exclusively Summit, and love it.
In my brewery, I find this to be true when the beer is fresh, but as it ages a slight amount (say 3-4 weeks in a keg), the Citra domination seems to calm down so I can find the other hop varieties.
Nice to see others using Cluster for a bittering hop for IPAs. Spares me from having to suggest it.
In addition to Cluster, Northern Brewer is also a great IPA bittering hop.
Now after your Cluster/Northern Brewer bittering hop addition, please proceed with Centennial/Amarillo/Cascade for flavor/aroma/dry hop additions, and you are good to go.
I like most PNW hops in my IPA’s but a Simcoe, Amarillo and Cascade combo used in a Basic Brewing Radio APA was excellent. It was a “15-minute APA” from extract. I like the hop combo so much I’m getting ready to keg an all-grain rendition of it. The gravity samples have tasted awesome! My version is more like an “Extra Pale Ale” at 6.2% abv so it may work in an IPA. The hop schedule for 5G batch per James Spencer on BBR:
2 oz. Simcoe @ 15 mins.
2 oz. Amarillo @ 5 mins.
2 oz. Cascade @ flame out
All late additions so more hops required for desired bitterness but awesome hop flavor and aroma!
EDIT I also don’t get the “cat pee” flavor it aroma from Simcoe that people refer to. A friend of mine who gets that aroma suggested because I’m using it in combination with other hops it may not show up. Others have suggested the Simcoe “cat pee” may me due to hop oxidation. I’ve used it twice and will keep doing so in this combination.
Willamette is my go to hop for Pale Ales. It has an earthy, english-like quality to it. There’s a little citrus in the hop, but not nearly as much as the others mentioned in this thread. For that reason I leave it out of my IPAs.
I had an all Perle IPA this weekend that was interesting.
when I subbed the citra for cascade i did it ounce for ounce. the aroma was very big so i decided not to dry hop with it and it turned out just right for my taste. AmandaK is right that the aroma subsides fairly quick. by the end of my dry hop the citra had struck a nice balance with everything else. this is my new favorite ipa to make.
