Hop ratios for an APA

[Shade]

My inlaws are coming this weekend, partly because I offered to my father in law to come and guest brew at my place.

I asked what style he wants to make, he pointed to an APA he had recently. The brewer nicely puts a lot of info on their website about the beer:
ALCOHOL CONTENT: 6.5% BY VOLUME
BEGINNING GRAVITY: 1.063
ENDING GRAVITY: 1.015
BITTERNESS UNITS: 65
YEAST: AMERICAN ALE YEAST
BITTERING HOPS: MAGNUM
FLAVOUR & AROMA HOPS: SIMCOE, CITRA, & AMARILLO
MALTS: PALE & CARAMELS

Using a American Ale yeast, this is a beast of a beer, which is high in alcohol and hop bitterness as an IPA should be. We have used all the soft bitterness hops however, to create a surreal explosion of hop flavour from the latest and greatest hops on the planet. Pine, citrus, orange & tropical fruits dominate the flavour and aroma of this beer.

Planning on making a 23L/5.5gal batch.

Hops come in 100g (~4oz) bags from my LHBS so don't really want the buy Magnum because I'd have a lot left over. To get that hop profile I'd probably use Amarillo for bittering, but I'd be interested in some advice about getting that aroma/flavour profile in terms of hop ratios and how much to add when.

And as a secondary concern, whether to go 95% pale, 5% crystal or mix it up a bit.

Thanks!

I would go 3% crystal and put something in for body/head retention. I would use a pale English caramel malt.

I would go 1:0.5:1 Simcoe:Citra:Amarillo keeping Citra out of the boil.

I would bitter with an economical bittering hop for as not to waste good aroma hops.

I would use plenty of hops, mainly spilt between a stand and dry hop at least 3oz in each

Thanks for the response!

For me in NZ, imported US hops are similar in price and come in 100g/4oz bags as I mentioned above so I am fine with using one of the hops I have. For instance, I can get Magnum for $11.50 and Simcoe for $12.00 (NZ dollars) so not much incentive to use Magnum since Simcoe costs about the same and will do a similar job.

I'm most interested in having the hops work together and not overpower each other so your ratio advice is helpful.

How does this sound:
.5oz Simcoe @ 60 mins (24 IBUs)
1oz Simcoe @ 10 mins (18 IBUs)
1oz Amarillo @ 10 mins (12 IBUs)

1.5oz Simcoe @ 0 mins
2oz Amarillo @ 0 mins
1.5oz Citra @ 0 mins

1oz Simcoe dry hop 5 days
1oz Amarillo dry hop 5 days
2.5oz Citra dry hop 5 days

(note, I try to aim not to have hops hanging around at the end so I've put the extra Citra into the dry hop)

Some of the online shops will do hops in smaller quantities. Craft brewing will do by the gram, baylandsbrewery by 50grams.

Good tip - Baylands doesn't (look to) break up the US hops I want to use into 50g, only seems to apply to a specific few - could get Warrior 50g for $4 but then I'm left with some extra Simcoe so will stick with plan A.

Also craftbrewing doesn't make it obvious if they do by the gram, only looks like 100g bags and a limited set at that.

I work up the street from Brewtopia/allgrain.co.nz so get my hops from there, seems cheapest in Wellington.
