Omission is not gluten-free. The fact that they can label it as such in Oregon is a travesty, and the fact that they can't label it as gluten-free anywhere else doesn't stop bars and restaurants and grocery stores from selling it as such. At least half the people I know with a gluten sensitivity, including myself, react to it. Their process is not based on medical research at all, it's based on on exploiting a flaw in the main test for gluten used in the beverage industry. The fact that many people don't "react" to it doesn't mean anything other than a) people often mistakenly self-diagnose a gluten intolerance when another issue may be present, and b) that gluten intolerance is a spectrum of disorders, and the only way to ensure something is safe for *everyone* is to avoid using any gluten-containing ingredients at all.
I also think it's not a very good beer. The lager is generic, I could just as well drink Budweiser (I react about the same, since Bud is made with quite a bit of rice and is about as low in hordein as Omission), and the pale ale has a weird aftertaste that I really don't like. I'd prefer to drink Harvester, Steadfast, or even New Planet over Omission's Pale Ale, even if I didn't react to the Omission. Sadly, they are made by Widmer Bros., who are owned in part by a major brewing conglomerate with the distribution and marketing budget necessary to flood the market with their product and steal shelf-space from beers that are really gluten-free. There are few things in this world that make me as angry as Omission, but I am confident that in time, as research improves, it will finally come to light that they should not be legally allowed to sell this product as "gluten-free". Then they'll be kicked to the curb where they rightfully belong.
