The ingredients of this product on Amazon.com indicates that the chips contain organic unbleached wheat flour. I contacted Ghiradelli directly to obtain clarification since these are also advertised as being "gluten free" on Amazon.com.
This is Ghiradelli's response to my inquiry:
"Thank you for contacting Ghirardelli Chocolate. Ghirardelli currently offers one product which contains a gluten ingredient which is our Milk Hazelnut Crisp Squares. The Milk Hazelnut Crisp Squares contain barley malt as an ingredient. As a result, the line on which our Chocolate Bars and Squares are produced, share a common line with barley gluten.
The Ghirardelli Chocolate Chips (Mini Semi Sweet, 60% Bittersweet, Double Chocolate Bittersweet, Semi-Sweet, and Milk Chocolate) line and powder line (hot chocolates and baking cocoas) will remain free of gluten ingredients. However, our Classic White Chips are made in a facility that uses wheat.
Ghirardelli takes the following measures to reduce cross contamination on our production lines: lines are cleaned between the changing from one product to the next.
Below is the correct ingredient list for the Semi Sweet Chips and the allergen information.
