I bought a bag. I've been eating some. They're good, and they indeed have the tang of beer. Pretty simple ingredient list, too (quoted from the bag):
Potatoes, sunflowr oil and/or corn oil, sugar, malodextrin, BEER (malted barley, corn syrup, hops, yeast), salt, honey (cane syrup, honey), yeast extract.Beer Chips. I love this town.
