I have found success using a light mounted polarizer in combination with a lens polarizer. It's not perfect, but it gets much of the nasty reflections under control. I've yet to try this technique with a troublesome bottle of drink that is curving in two directions. I used this technique in the attached photo.http://www.miketaylorphotoarts.com/uploads/1/3/5/1/13516347/gran-orendain-comp-1-web_orig.jpg
