Porridge! (rolled oats)

[beanstalk]

Are these essentially porridge oats then? Want to make an oatmeal stout tomorrow morn...

[robotmonkey]

Yep, same thing 

[beanstalk]

Here's the recipe I'm thinking: Any thoughts? Should I up the % of oats?

I thought i'd go for a slightly higher bitterness because I want to add a fresh vanilla pod in the primary to offset it a little...

It's looking like it'll be a little light on colour too maybe I should up the crystal or roasted barley.

[DEMPSEY]

Porridge is what it is ok A typical dry stout recipe would be 70% pale 20% flaked barley 10% roast barley so you could up your roast % to bring up the colour.

[beanstalk]

Thanks! Well i think i just might have enough porridge in the house to up the oats a little, but wanna leave some for my working week!

I wonder what porridge would be like soaked in this stout... 

Anyway, here's what i'm thinking now...

Right so I've brewed this recipe and the OG, instead of the 1.048 estimated, has come out at 1.060! It's bubbling away now, and I have just exactly 11litres in the primary. What went wrong i wonder? did I udnershoot my efficency?

I did it in a simple BIAB.

[TheSumOfAllBeers]

Have you factored in your liquor calculations? Usually when you see an efficiency spike it means that you ended up with less liquor than you planned

[molc]

I've had the same happen a bit as I'm dialing in my efficiency in all grain. I just use the dilution calculator in Beersmith to dilute down to the appropriate gravity, both pre and post boil. You want to get the correct pre boil gravity, otherwise your hop utilization will change due to the different concentration of sugars.

This.  Or this AND you got better efficiency.

I was going to tell you to either mill the rolled oats or crush them well with a rolling pin to get more out of them.

What was your sparge procedure like?  -Single batch, double batch, fly or no sparge?

[beanstalk]

Cheers folks. I'm still getting used to beersmith, but it was saying no sparge just 18 litres mash water to end up with eleven after boil. I did fly sparge with one litre just to rinse the  bag and bring the pre-boil up to 16litres as it suggested in beersmith but I don't understand how I got such a high gravity. Maybe it was the oats or something. I used lidle jumbo oats, but I would have thought smaller oats would be more efficient?

[beanstalk]

Beersmith was saying I should have gotten 1.046 gravity

[beanstalk]

@sumofallbeers: please excuse my ignorance, but I'm not sure what you mean by liquor calculations?

[johnrm]

Maybe means Wort?
