Oatmeal Stout Help

[Donny]

Hey guys,

Need some help with a recipe that got from a book that I would like to try. This will be my first all grain batch and Il be using a 33ltr mash/boiler.

The recipe;

Total Liquor:32L

• 4.2Kg pale malt
• 250g rolled oats
• 200g crystal
• 160g chocolate
• 70g roasted barley

Hops:

• 40g Challenger 60min
• 16g Challenger 0min
• 16g Golding 0min

Mash liquor 12L
Mash Temp 67C
Boil 70min

Is the total 32ltr the overall water used? i.e in total you will use 32ltr but will loose water through the boil and the mash ending up with around 25lt or less of wort. Sorry for the newbish style question but Im very new to all grain. Any tips would be appreciated

Buy Beersmith and set up your profile, it will just save you calculating your vols in future
You use 12l for Mashing
Then you sparge with 20L to rinse any remaining sugars from Grains.
If you were BIAG the whole lot would go in, 4-5L would be absorbed by Grain and on 60Min boil you would lose the same again.

Thanks for the clarifacation. With the BIAB can you top up with water after to bring up the volume? How would that affect the wort?

[Leann ull]

You can but no need do it just your full water vol to start.
Beersmith allows you to bump water vols and will calc increased grain and hops bill if you want a bigger final volume

[Donny]

You have successful convinced me to buy beersmith

Is there enough dark grain there? Only 6% of the bill between the chocolate and roasted barley, I'd push it up towards 10% personally.

Put the recipe in as is in Beer Smith and them you can adjust the percentages using the simple slide rule
It will adjust grain percentage as you do.

I plugged your recipe into brewersfriend.com and the SRM value is only around 21. I'd definitely be putting some more chocolate malt in, maybe even double what you have there based on the volume you posted. What was the target volume in the recipe book you used?

What was the target volume in the recipe book you used?

Just over 5gal

I didn't see these posts until after I had bought my grain. Ended up like this

4.2 kg - Irish Craft Pale Ale Malt
250g - Malted Flaked Oats
200g Crystal crushed grain 225 EBC
160g Chocolate crushed grain
70g Roast Barley crushed grain 1300E

Still learning here. It will be my first all grain brew. Only done extract kits and partial mashes until now. Have a handfull of meads under my belt but beer brewing gets results faster.
