<<Disclaimer: Verify this information before applying it to your situation.>> List mates, While I received only a limited number of responses on Nakano Seasoned Rice Vinegar, the results are in favor of the GF status. Only one person indicated any problem/concern with the product. Several people indicated they used the Natural Rice Vinegar with no problems. Two people indicated they used the seasoned varieties with no problems. One individual has a response from the manufacturer indicating GF status for the entire product line. Another individual had a response to an inquiry on the Natural Rice Vinegar indicating it was safe for us to use. Hope this helps those of you that haven't tried the product yet. I have had no problems with the product personally. I also have no personal interest in the product or company, just looking for ingredients that are safe for us to use. Thanks to everyone that responded to my inquiry. Dave Taylor, Mentor, OH.
