Abstract: A drinking vessel product includes a wine glass with an inner cavity filled at least partly with wine. The wine glass has a body that defines the cavity, an upper opening that is sealed with a removable seal such as a metal foil, and a smaller fill opening at the bottom. The glass includes a support that is attached to the body and that includes a pedestal, a stem and a stop formation that seals the fill opening. The body and support are molded from plastic materials. The cavity is filled with wine after the upper opening has been sealed, by inverting the glass and filling it from the fill opening, before fitting the support to seal the fill opening.
