Are Reeses always gluten-free?

Reese's Pieces are a candy-covered peanut butter treat created by Hershey's, and on Hershey's own website they say that these candies are gluten free! ... That means you won't find a GF label on the candies. So, these have never been tested to be gluten free. Reese's Pieces just don't contain any gluten ingredients.
