Default Deuchars IPA Clone Recipe?

I've been looking for a good Deuchars IPA clone recipe but haven't had much luck finding one.

For those of you unfamiliar with it, this is a really nice lighter IPA session beer around 4% ABV.

Has anyone seen a good one around? Preferably a partial grain recipe?

Thanks,
John

Here's your start.

Quote:
Ingredients

Malts: Golden Promise and Optic.
Hops: Fuggles, Super Styrian Goldings.
“Deuchars IPA is a fabulous beer. A brilliant blend of malt and hop character and above all a drink with enormous drinkability.” Roger Protz, Editor of the Good Beer Guide.
I drink it all the time and it's the one I go for if there is not any guest beers on. Lots of the bigger pub chains have it as a house ale

I'm stabbing at around 30 IBU and colour of about 8(ish)
They have only listed the base malts so it's probably going to have some crystal in it.
It's a very good beer and it's refreshing. If I was going to brew It I'd put a small amount of wheat in it to give it that summer beer feel.


So far.

Golden Promise
Optic
Crystal
Wheat
Fuggles
Stryian Goldings

IBU 30
SRM 8
OG 1040

Yeast, I'm not sure but it's got to be worth a shot with a Scottish ale yeast.

If you are looking to go for a PM I'd use the Golden promise as the base malt (LME) the mash the Optic and other grains.

A word of warning for brewers looking for an American style IPA.
This is not it.

It's just a Pale ale. A good one but not a real IPA.

I emailed the brewer shortly after leaving Scotland. He was very up front. Here is his reply.


Quote:
Hi Ryan,

I'm so pleased to hear of your affinity for IPA, but I assume supply could be problematic in Montana!

For our, malt we used to use entirely Golden Promise, but, due to supply and quality, we now use a blend of around 65% Optic. However, malt from varieties such as Marris Otter is an excellent one, and if it works well micro brewery and home brewed beers I would stick to something like that. We also add around 3-5% wheat malt to the final grist. We also use around 10% sugar to control colour and help fermentation

We use very high hopping rates due to our late hopping in traditional hopback and as a result only achieve around 20-22 % bitterness utilization, aiming for a final bitterness target of of 28 for both the draught ( 3.8ABV) and bottle (4.5ABV)

For home brewing I would tend to go for the higher ABV version!

We use Fuggles as the main copper hop at a level of around 10% of total hops –around 0.2 g per litre



We use Styrian Golding as the main hop, these days blended with Willamette, which we find compliments the aroma and also acts as a buffer against the variable quality of Styrian Golding . If you can’t get Styrian Golding, replace with Willamette initially

The usage rates in g per litre are as below for all hops



Copper Late

Styrian Golding 0.25 1.75

Willamette 0 0.4

Super Styrian 0.2 0

Fuggle 0.2 0



If you can't get any Super Styrian simply add more fuggle (around 0.3 g per litre) or some other variety of your choice such as Challenger or perhaps US varieties like Liberty or Mount Hood.



To get more late hop character why not try "hop tea". This is simply made by bringing hops to the boil in Water for around 5-10 min ( too long and you will add too much bitterness), straining and cooling and adding the resultant "tea" at the end of fermentation. Remember to allow for dilution effect on the original brew! I suggest you start in the range 1-2 g per litre



Simply add any variety ( in this case Styrian Golding /Willamette) but you try other varieties to give different characters



I hope you find this useful – good luck and cheers!









Regards





Robert

I asked a follow up question about yeast and he went as far as offering to send me some. I am a Caledonian fan for life.


Quote:
No problem – I hope it turns out OK

Only thing I forgot is the yeast – we expect fermentation to be complete within 48hrs at 20 degrees C

This can be problematic for home brewers, but I would avoid too high a temperature as this will cause flavour changes and use fresh active yeast, even if that requires growing up a starter culture of dried yeast in some sugary nutrient first.

Yes we have our own strain

I would be glad to send you a small sample but I’m afraid we only have it in slurry form and it would autolyse during transit.

I suggest you sue whatever yeast your home brew friends find to be the most reliable – you could take a sample form their fermentations and use that?

Regards



Robert

Cool, good info.

Here's my update guess then.

So far.

Golden Promise - 65%
Optic - 15%
Crystal - 6% (Although not mentioned I think it may be too dry without it. I think I'd need to do a sample brew to decide.)
Wheat - 4%
Demerara Sugar - 10%
Fuggles - Bittering
Styrian Goldings/Willamette - Flavouring/Aroma
(Styrian - Hop tea)????

IBU 28
SRM 8
OG 1040

I've not run this through any software so it need playing with.

It sounds like they use a massive amount of hops in the hop back.
I think it'd would be more economical for home brewers to just load up the late addition hops. Remember this is comparably not a massively hoppy beer. Just enough to be pleasant.The hop tea may be worth ago.

I'll run it through Beersmith and round the figures up or down to keep it simple.

Default Thanks!

Wow! Thanks Orfy and Fifelee!

I'll be brewing a 5 gallon partial mash.

Are the amounts given for the "US Partial Mash (3 gallon pot)" actually for a 5 gallon or a 3 gallon batch?

Also, since I'm new to this, I'm not sure exactly what the following lines represent:

Excellent. Thanks again Orfy!

It looks like my LHBS does not not have '1 lbs 1.2 oz Pale Malt, Optic (3.0 SRM) Grain'. Can anyone recommend a good substitute?
