Oatmeal stout

[time01]

I'm looking to make an oatmeal stout for winter and hoping I can adjust recipe below I have used previously from database, trouble is I'm not sure on what to drop or add to make it an oatmeal stout?

I'd also like to bump it up to 5.5-6%

And finally do I just add oats to boil like grain.? Any specific oats required?

Three shades of stout
4.5 kg Bairds Golden Promise Pale Ale Malt
2 kg Weyermann Pilsner
1 kg TF Brown Malt
0.7 kg Flaked Barley
0.5 kg TF Roasted Barley
0.5 kg TF Pale Chocolate Malt

For oatmeal stout, I use a base stout recipe and add oats. No need to replace grain.
How you use it depends a little on the type of oats but I presume you mean mash rather than boil.
Look up adjuncts, gelatinisation and cereal mash. Pre-gelatinised oats can be added to the mash with no special treatment.

I like to toast mine first though - nutty.

Thanks manticle.
Yes your right I meant mash
How much oats would you recommend? I've read comments for it to be 5% of grain bill?
I've previously used danstar Nottingham British ale yeast, any others you would recommend for this style?
I found the below oats from craftbrewer, I'm assuming I could use rolled oats from supermarket?

Those oats are the right ones, they can also be called flaked oats. Just call into the supermarket and grab some off the shelf or from the LHBS.

Percentage wise start with 10% and work from there, I use 12% and find that adds the right complexity to make the style. Often I use about 5% flaked oats in American amber ales and black IPA to add mouth feel and creaminess.

 

[Tahoose]

My first attempt at the style. Was aiming for a thick to chewy mouthfeel, hopefully really nice and smooth. Steeped the black grains overnight in cold water and added at the end of the mash.

Have you added gypsum to malt driven dark beers before Tahoose? General recommendation is to avoid adding sulphate to dark beers although with some of the more hoppy styles like American browns and blacks it can work.

I would have gone for cal chloride but see how you go.

 

[Tahoose]

No I haven't, first really dark beer that I have made to be honest. I was trying to push the malt mostly.

Also was deliberately liberal with crystals.. I suppose I'll just have to suck it and see.

All up I used about 2 tsp's in a 4.9kg grain bill.

 

[manticle]

Calcium chloride is the salt you want to use to push malt. Calcium sulphate should accentuate dryness and hop character.

 

[Tahoose]

Think I hit the wrong button when I was plugging in the recipe. Pretty certain I did actually use calcium chloride in the mash.

Hi tahoose, what's the reason for steeping black grains over night? And what's the process? Also why do you add them at end of mash?

 

[Tahoose]

Paging manticle here.

From my understanding, it reduces astringency. The process was simple; milled by black grains, added 2-3 litres of water and put that container in the keg fridge. Added the contents after I'd hit my mash out, stirred the mash again and ran into the kettle.

It's also has something to do with the ph level of the mash, like I said I'm not totally across it so hopefully someone with a better knowledge can throw in a few words here.

 

[manticle]

You're pretty much on it tahoose. A lot of roast can reduce pH too low so brewers find ways to combat it. A common one is adding chalk but this is not super effective due to chalk's relative insolubility. Some don't enjoy the flavour contributions chalk brings either.

Adding roast at the end of the mash means you can get pH right as for any other beer, it will buffer itself pretty well by that point. Cold steeping simply allows full, smooth flavour extraction for the belated addition.

 

[Tahoose]

Thanks for the clarification.

 

[time01]

Thanks for the tips boys, I read a bit more about and it makes sense. A few articles suggested adding it at the end of the boil as opposed to end of mash, anyone tried this? Also any tips on yeast for this style?

 

[manticle]

If using liquid, I have used WY1469, 1084, 1099 and 1275 and been happy. 1469 is my favourite.

hi guys, after a bit of critique on my latest recipe, thoughts?
aiming for say 5.5% with 33 IBU
70% Maris Oter
10% flaked oats
5% pale chocolate malt
5% roasted barley
10% crystal malt dark (should this be a combination of crystal dark and crystal medium?)

appreciate the feedback, the reason for the thorough research is a I brew a bday stout for sons bday each yr. 1st yr was an extract, 2nd was my 1st all grain stout, this yr I want to step it up a notch.

bump

 

[Tahoose]

Time seeing as this is the first time I've ever made a stout, and I'm not a regular stout drinker I can't really critique the recipe.

Tbh though your recipe there doesn't look much different to mine. I think the other thing is with this beer is that yeast plays a big part. I ended up using wyeast 1084 irish ale. As Manticle said 1469 west Yorkshire is a nice English yeast for a few styles.

Kegged mine tonight and drank the entire hydrometer sample, very tasty, looking forward to having this on tap.

Also currently sipping a sam smiths oatmeal stout which I picked up on the weekend for something to compare too. At first (probably too cold) I found this over carbed and too much liquorice. But now as it warms up a little it really nice and smooth and the roast flavours are starting to shine.

Thanks tahoose, be sure to post how yours turns out

 

[Tahoose]

I'll try and remembers, I suppose it depends on how many I've had..
