Don’t: Drink it. Beer is made with malted barley, a source of gluten. A double no-no would be a wheat beer like German Hefeweizen, which packs a double punch.
Do: The exception to the rule above is to order a gluten-free brand made with buckwheat, sorghum, rice or corn (see an extensive list here).
Do: Have a cider if you’re craving a pint of something fizzy.
