Never had much luck with normal oats, never noticed that creaminess in the body or smoothness, regardless of using traditional, rolled, quick, added to the mash, cereal mashed ( 19% in a mild ) so I just use malted oats. Don't use them very much but I found them when I was looking for crystal so figured they'd be good for a porter. Ive used malted a few times before but can't really remember how much contribution they made. Last time was only 3% so we'll see this time.
If I don't feel that I can pick up any contribution this time i won't get them again. Could be me though, I've had commercial oatmeal stouts that I don't think we're more creamy than others. Maybe I'm expecting too much, or have poor taste buds haha
