A retaining member for use with a vacuum-insulated vessel is described. The retaining member may include a body and a deformable member. The deformable member may have a first layer and a second layer extending from the first layer to a resilient end of the second layer. The resilient end of the second layer may define an opening of the second layer and the opening of the second layer may be aligned with a first aperture of the body and a second aperture of the body, to receive and securely hold a bottle such as a wine bottle within the opening, the first aperture, and the second aperture. The second layer may be resiliently flexible between a first position and a second position of a peripheral edge of the resilient end, to receive and retain bottles having various sizes.
