Some information conflicts. For instance, here is a Nestlé gluten free product listing:

Gluten free product listing (PDF) as of August 2009.

And in their FAQ (under Nestlé Brand Categories --> Tasty Treats --> Chocolate, Sugar Candy and Snacks), they report the following for Wonka candies: Almost all the WONKA® candies are gluten free except WONKA® OOMPAS® and the WONKA® Bar. We recommend that consumers always read the ingredient statement for the most current information.

The FAQ entry from this page may be telling:

• Q. Looking for LEAN CUISINE® products which might be Gluten free. Is there a list of NESTLE® products which are Gluten free?
• A. Unfortunately, we cannot provide a list of NESTLE® products that are gluten free. Most of our products contain gluten or a derivative of gluten.
