Notes

This is a recipe for a smooth and rounded Oatmeal Stout that is appealing to those that wouldn't ordinarily go for a roast style beer.

Use KCl (potassium) rather than NaCl if you have it
Adjust mash pH to 5.4 with lactic acid

My water profile is soft so needed some of these mineral additions

Add dark grains marked 'late addition' at start of sparge to reduce extraction of bitterness but still adds loads of colour. SRM will be around 38 using this method rather than the 46 indicated from the app.

May require a longer mash period due to borderline diastatic power. Check progress with a refractometer and iodine tests.

I've tried this one with Safale S-04 yeast and using the Irish Ale yeast wins hands down.
