How much oatmeal for stout

[Gerrydp22]

I'm planning on doing a 2.5 gallon brew of oatmeal stout with a coopers Irish stout and 500 grams of dme. Just wondering if anyone can help me on how much oatmeal to use? Thanks

12-16 oz should be enough for that batch size.

Consider toasting it on a cookie sheet in the oven at 300* for 30-45 mins beforehand to bring out the oatmeal flavor. Once you really start to smell the oats, they're done and ready for the brew.

Great. Thanks. I read I should boil for 60 minutes and then strain. Does that sound about right? Thanks again for any help

I'm using flaked/rolled oats as they have their starches pre-gelatinized and don't really require cooking. I'd stay away from steel cut oats that do require cooking.

Oats, however, do not have the enzymes to self-convert and you must do a mini-mash with say a pound of 2-row malt. Otherwise you'll end up with unconverted oatmeal starches in your beer and that is not a good thing.

Classic porter grist (works really well):

For an oatmeal stout brewers added even less than 1% oats! The cheats!
