Does This Cpa Recipe Look Ok? Pesky Conversions...

[piraterum]

Hey guys,

I'm going to have a go at the Coopers Pale Ale clone in the RecipeDB:
http://www.aussiehomebrewer.com/forum/inde...&recipe=483

I'm currently doing partial mashes does this conversion look about right?

My setup:
Mashtun holds max of 2kg grain
Typical boil volume = 8L
Typical efficiency = 65%

1.9kg Export Pilsner Malt
0.1kg Wheat Malt
0.01kg Dark Crystal
1.5kg Light Dry Malt Extract
0.5kg Cane Sugar
47g POR flowers (9%AA) boiled for 60min
Recultured CPA yeast

According to Beersmith:
Est O.G. = 1.052
Est F.G = 1.014
EBC = 10
IBU = 28.2

Does that look like it's in the ballpark of the imfamous whiteboard recipe? :huh:

cheers,

Piraterum

Hey guys,

I'm going to have a go at the Coopers Pale Ale clone in the RecipeDB:

Piraterum

Two things.
1. It probably won't taste like the CPA you buy.
2. It'll probably taste better.

recipe looks fine and the calculations okay. Go for it.

28IBU is over the top IMO. I made one at 26 IBU and the bitterness stood out. That may or may not be the fault of the POR (sorry Tony) so maybe FWH is the go. Or else bitter to <20 IBUs and use another neutral bittering hop, NB comes to mind.

 

[AndrewQLD]

I'd reduce the O.G down to about 1.049 and lower the hop amount accordingly.

28 ibu's is spot on for this recipe and I haven't noticed any harshness.

Since your doing a partial I'd mash your grains on the low side, say about 63, the extract won't attenuate as well as an all grain brew so this will help to get your F.G down to around 1.005 where it should be for this beer. Aerated the crap out of your wort and pitch a larger than normal yeast starter.

Cheers
Andrew

Thanks everyone for the feedback. This forum rocks :beerbang:

 

[drsmurto]

Hmmm. Not sure i agree with you on this one Andrew.

The Coopers Pale Ale kit only comes to 19 IBUs when made up to 23L as directed in the can.

Now i know using a kit as proof of concept is a weird thing but dont you think Coopers would make their CPA kit closer to the real IBUs?

I am not saying your wrong as such, i just think 28 IBU would stand out in a beer as thin as a CPA. Particularly if the beer is going to finish as low as 1.005 after mashing low and adding bugger all crystal malts.

The proof is in the pudding, I've brewed this recipe many times as have others on AHB and I can't say I noticed any harshness, give it a brew and see. 28 ibu's is what is the recognised bitterness levels for this beer.

The Coopers pale ale kit is not anything like the CPA that this recipe emmulates so there is really no comparison.

hmmm there seems to be a supply problem with POR hops at the moment.

I'll have to use pellets instead of flowers. Did i read somewhere flowers give better aroma than pellets?

Smurto: The kit is less IBU because homebrewers are encouraged to use sugar adjuncts.

FWIW, CPA goes from ~1.038-1.004. You're probably better off starting at somewhere around 1.042 as you won't get nearly the same attenuation as coopers do.

The flowers are much less harsh than the pellets are when it comes to "that POR taste" that people dislike. If you are using pellets I would heed the advice about part-substituting with a neutral bittering hop.

As in the above recipe?

 

[Adamt]

Uhh... like, more adjuncts... :unsure:

Real CPA has no sugar anyway

 

[Blackfish]

I gave up cane sugar ages ago, but followed this recipe because it was "copied from the whiteboard" <_< .

My advice, lose the sugar! Unless you are nostalgic for the taste of the CPA KIT, not the real thing!

Considering the extract in this recipe, I'd keep the sugar in, otherwise it might end up with too low attenuation.

For my next AG version of this I'll be omitting the sugar.

Hi all,

I have done this beer many times and it comes out very very close to the real thing.

If you are substituting extract and then adjusting bitterness etc I dont think you will get close.

The AG recipe that Andrew has put up will give you an excellent clone.

FWIW I tried it once with a 1056 yeast because the starter I made was doubtful an it was nothing like the real thing.

Cheers

Yes, the yeast is the key. Versions I've made with other yeasts have also fallen far short.

BTW, I'd strongly recommend trying the Coopers yeast in other styles. I used it in an amber ale a little while back and it was a cracker. And of course in a Cooper's Dark Ale clone it is amazing.

I tried Coopers yeast in a Dark Ale and it turned out well, went from 1.056 down to 1.015 and gave a nice finish.
If there was a hint of a banana taste you sure can't taste it through the strong malt flavours of the brew.
