I'd like to experiment with gluten-free oats to see if this is something I can tolerate. I'd prefer an oat flour to an "oatmeal" as I have a slice of challah twice a week and the rest of the time I'm pretty much grain free. I'd prefer my oat experiment to be in place of my weekly rice bread, not in addition to (I'm on a low carb diet for weight loss, in addition to being unsure of how grain products in general affect my overal health.)

If gluten-free oat flour isn't available, what brands of oats are gluten-free and how hard is it to grind my own flour? Would a coffee grinder work? Would I need to get a new one or is it easy to get coffee residue out of a coffee grinder?

Here are all the manufactureres of gluten-free oats:

Only Oats
Bob's Red Mill
Glutenfreeoats.com
Gifts Of Nature
Creamhill Estates

The only one that offers oat flour is Only Oats. You can make your own oat flour in a blender, coffee gringer or food processor. Just put the oats in and process until finely ground. I don't have a coffee grinder, so maybe someone else can comment on that part of your question.

HTH.
