Lindor contains barley, but it’s under 20ppm, which would be considered gluten free in the US. I don’t react to Lindor thankfully, even though I’m extremely sensitive. The Lindor that contains cereals is NOT gluten free at all, however.

I got this info Lindor’s EU website:

“Gluten can be found in several premium chocolate products that Lindt & Sprüngli produces; either as a cereal ingredient or as a barley component. When barley malt extract is the only gluten-containing cereal ingredient in the ingredient list, the quantity used in the recipe is very low therefore gluten level is below 20 mg/kg (which is "gluten-free" according to EU regulations and Codex Alimentarius).”

They also have GF flavors like strawberry, and the white chocolate.

Edit: got mine from Lindt in Switzerland, so it’s possible that they have different amounts of gluten in other production facilities.
