I had checked the archives and could find nothing on Yoo-Hoo so I tracked
down the company and called.

I just got off the phone (201) 933-0070 with a rep at Yoo Hoo Beverage
Company.  They make a chocolate drink called Yoo-Hoo.  Yoo-Hoo comes in
juice boxes, bottle and cans.  She indicated to me that they had the
product tested and both the ready-to-drink original chocolate flavor and
the strawberry flavor are gluten free.  Their syrups which are sold
separately to add to milk, however, had not been tested and she couldn't
guarantee those.
