Colour issues with stout

[Eoin]

They are listed as part of a partial mash, but it's not really a mash due to needing some proper mashable malt. Also the oat part of the total grain bill is quite high. I expect it would actually settle out to black if left sit for long enough, but it would take a month or two sitting, if not longer. I find my oatmeal stouts had a large amount of the powder at the bottom of the fermenter despite being part of a full mash.

Just an update, as Eoin predicted the colour has darkened up considerably. It appears there was quite a lot in suspension. Kegged today.

First glass from keg. Has dropped jet black. At 3.8% ABV am delighted with the body and flavour.

I'd expect it's quite silky with all the extra starch. Next time you do the same add in a pale malt addition so that it mashes correctly, you'll see a difference and get some use out of those starches which now have just dropped to the bottom.
