I visited Bertolli Pasta Sauce and asked them if any of their products had gluten in them. This is what I received from Bertolli:
"Ingredients that may contain gluten are always listed on the label. Accordingly, the best way to determine whether a product contains gluten is to check the ingredient list on the label. If you are allergic or sensitive to gluten and cannot determine whether the product contains gluten, we suggest you do not use it."
