I just bought the liquorice flavor of these as a holiday gift for an exchange at work. The recipient has to eat a gluten-free diet and she loves licorice (and has trouble finding gluten-free licorice that isn't gross), and I couldn't see anything on the tin that looked like trouble. It's devoid of any useful info.
Does the website have any gluten-related information? Their English text is just about how delicious the candy is, which doesn't help me here, and I don't speak or read French.
