But scientists say the test doesn't detect all potentially harmful gluten fragments. Recent tests by Canada's public health agency found gluten fragments in beers from Spain and Belgium that use a gluten-removal process similar to Craft Brew's.

Nearly two in 10 adults buys or eats food tagged "gluten-free," sometimes just to support gluten-intolerant friends or family, the market research firm says.Twenty percent?

The fortunes of Omission and breweries like Harvester (100% gluten-free; no gluten-based grains used) hang in the balance.
