Alternative for Ahtanum in Punk IPA

[Dunfie]

As some of you will know I am a big fan of Punk IPA. I have already attempted a clone but it didn't have the big, in your face, grapefruit hammerblow so I am planning to try another over the next month or so.

On the Brewdog website the Punk IPA brewsheet mentions that Chinook, Ahtanum and Nelson Sauvin are used in "bucket loads". I have never used this trio but I am assuming that the Chinook are the copper hop and the that the Nelson Sauvin are likely to be the aroma hop. So my question is, where does the Ahtanum come in and what would be a good alternative. Also, would I get away with just using Chinook and Nelson Sauvin?

Cascade maybe?

I made a hoppy session beer for a mate with that and I'd say it has a grapefruit taste.

Surely if you want Grapefruit then it has to be Amarillo . . . which is a supercharged cascade . . . Ahtanum is not High Alpha IIRC probably coming in at around 5-7%

I would bet the hopping schedule would be something like Chinook for bittering, and then an insane amount of Ahtanum/Amarillo for flavour followed by the NS for Aroma . . . but to me It would be a waste of the NS hop as that "C" Hop profile would really dominate

Thanks TM and A - great suggestions. :thumb:

I have both amerillo and cascade in the freezer somewhere (although the amerillo is well out of date). Hopefully get a chance to through this one together in a couple of weeks.

I'll have a brewday thread where I will post my attempt. :thumb:

I love Punk IPA, every bottle seems to taste different.

Amarillo is a good sub for Ahtanum. The predominant hop is Chinook, even through middle and late additions.

Here's my recipe, US-05 is the yeast. The malt should be lower colour MO.

If you can get your hands on a copy of Jan-Feb 2010 Brew magazine from Brew Your Own ( its a US mag ) there is a great article in there on Brewdog, they have clone recipes for Punk IPA, Rip Tide Stout and Hard Core IPA. Their recipes are usually published as all grain and an extract versions.

Unfortunately they publish the recipes based on 5 US gallons ( 19L) and tend to use pellets (this makes me weep as most of the hops we can get our hands on are whole as you know. I would love to get hold of the pelleted versions as whole hops are such a waste if like me you only brew occassionally) so there is a little bit of jiggery pokery to get to a 25L batch and to modify the hop bill ( they use hop utilisation of 25%, but if you want to use whole hops you will also need to increase the hops assuming a factor of 10% less utilisation).
I don't think I can give the recipe here as it would be an infringment of copyright. Just to say they use Columbus in for the whole boil, Ahtanum at 0 and dry hop with Amarillo. They used a Dry English ale yeast from White Labs.

you can subscribe to the mag from there, I liked it so much I have a 3 year subscription which saves a load money. There's loads of other stuff in there and what those 'mericans get upto at home is amazing, they are years ahead of us kit wise.

Actually only using a factor of 25% for hop utilisation is somewhat flawed it is easily possible to get 30% utilsation and using a formula to determine IBU contribution is a much more accurate way of doing things as it takes into account Alpha acid content, Boil Duration, Wort Gravity, and kettle factor.

There's loads of other stuff in there and what those 'mericans get upto at home is amazing, they are years ahead of us kit wise.

Indeed they are, but that is because there are a lot more people home brewing in the US . . the majority of which are all grain or extract (Here in the UK it is mostly kit brewing, with about 5% All grain . . . if that). They are also more prepared to spend money on kit built to do the job rather than "Bodge it Cheaply and Make Do" which is the prevalent attitude over here. . . . When you do get well made kit for sale the number of posts you see about people saying I can make it for a third of that . . . or look how much this plonker paid for . . . Tends to put people off making and selling good quality kit though.

BYO is a good mag though . . . Brewers Porn a bit like the More Beer catalogue. . . . The one I miss is Brewing Techniques which was excellent. . . . Brewers Contact is pretty good though, with some excellent articles in, and biased towards the UK market . . . and very few adverts . . . Which reminds me I must finish Proofing the March Issue :whistle:

Really? am I in that much of a minority? I suppose kits are pretty easy and not everyone has my 'tinkering' obsession.
