<<Disclaimer: Verify this information before applying it to your situation.>> There are several areas of concern with regard to ice cream. The primary one as I understand it is the flavoring and the potential use of grain alcohol in the extraction process.(ie: vanilla extract ) It is not enough to trust labels you must question the source of the 'colorings and flavorings you see listed there. Contact the manufacturers directly for a list of which ice creams are GF. You may still have a difference of opinion about the potential of Gluten contamination through the use of grain derived extracts as some chemists believe they are removed during the extraction process. A more obvious area of worry would be in the flavors that include any type of 'caramel' or caramel coloring. Chocolate would seem to be a safer choice because it is often produced without the obvious vanilla extract, however, according to an industry source , chocolate is the perfect 'dumping' ground for other flavors that the company wants to get rid of. Only by directly contacting the Manufacturer will you learn the answers. Good Luck.
