Keeping the background white while preserving detail in the glass is tricky.
This technique is called "bright-field photography" or "bright-field illumination" should you want to Google it, and yes, it can be very tricky to get it right.

This worked OK but the foil created new problems in that it created unwanted gray tones on the white sweep at the bottom of the glass. The foil did help add a thin dark line to give the edges of the glass some separation from the background though.
I think the main element I was missing was adding a light from underneath. The time factor and budget made this not possible so I did the best I could. I need to get some thin white lucite sheeting so I can practice adding light from the bottom.
Instead of (or in addition to) white Lucite, try clear glass. You can set the stemware on the glass, which is elevated well above the floor. Then you set black panels on either side of the background, just out of frame, and another underneath, also just out of frame. The black panels reflect on the edges of the stems, giving them outlines to delineate their shapes, but because they're sitting on clear glass there's no "unwanted gray tones" or reflections under the base of the products.
If you're only shooting glass, this method only requires one light, the background light, which greatly simplifies the shot. The background can be opaque white material, lit from the front, or translucent material, lit from behind. Either way works fine. Meter the background, and add two stops or so to bring it up to white level.
If you're shooting glass and accessories, like the bottles and stoppers example, you'll need additional lighting for the accessories, but it needn't be too complex.
HTH.
