AG#2 Effin Oastmeal Stout

[sam.k]

Really? We always used to use the stuff (under 5% of the grain bill) and I can't remember having a problem in the past.
Guess things have changed, whats the suggestion these days?

The effin recipe should have enough with the oats and the flaked barley especially if you do a glucan rest. But for a bitter or pale ale wheat malt is better IMHO a better taste.

Ah good to know, many thanks.

 

[graysalchemy]

I also add oats to pales and bitters as well as wheat malt it adds a subtle flavour and smouthness to the beer. Don't roast it (except for dark beers)and don't forget the glucan rest.

Guiness do something crazy with nitrogen to get that creamy head. never heard of anyone recreating it at home.

 

[zgoda]

Inject some air with syringe into your pint. Air is >70% nitrogen, right? :)

 

[Aleman]

Head retention is always going to be an issue in a beer that contains oats as unfortunately the oats contain high levels of oils that destroy the head. The higher the level of oats the worse the head retention

Apart from using some PGA there is no way to improve it really. Guinness use 20% flaked Barley which doesn't have the oil content so has a much creamer head (even without the nitro injection)

Thanks for explaining that...

The head rention is on a par with many stouts I have had at beer festivals so not bothered at all about it really.

Its a fantastic pint and I have numerous request to get it made again :)

I have to concur with dx4100, it's a great drink. Really good depth of flavour to it, I would recommend it to anyone looking to make a stout, I'll certainly be revisiting it. And very moreish too, always difficult to stop at one.

Thanks to Aleman for sharing the recipe, cheers!

It is far more complex than most commercial stouts you will try, once you drink this you will never enjoy a Guinness ever again. :thumb:

I fired this into Beer Smith and it came out a reddy colour, is that right?

 

[graysalchemy]

No it is a dark beer should be about 200 EBC :thumb:

Where am I wrong

 

[graysalchemy]

By the looks of it you need another 100g of roasted barley, think you have typed in the wrong figure. :thumb:

 

[CoxyBoy123]

This has jumped it to 27.4 SRM sound right?

 

[graysalchemy]

Well I have just typed your figures into beer engine and it went from about 100EBC to 202EBC just by increasing the roasted barley to 130g. Also you seem to have used a light 10L crystal malt.

Don't know what is happening with your beersmith but you should have an srm of about 100 i would have thought.

hmmm changed it to 120l, now at 29.6 SRM

 

[Aleman]

This was the last Grain Bill I used for 80L at 75% Eff

12000g Pale Malt
2250g Flaked Oats (Toasted - 45 Minutes in oven at 150C Or until golden brown )
1000g Chocolate Malt
1000g Flaked Barley
750g Brown Malt
750g Crystal 120EBC
250g Roast Barley

And it was a lovely black colour

 

[graysalchemy]

Your srm figure for the roasted barley looks low as well I would have thought it would be nearer 500.

This is annoying me, can you put me one together for a 3 gallon batch and I will punch it in?

Mash with 2.83 gallon and sparge with 2.66 for pre boil
