A reusable bottle cap system includes a bottle cap and a bottle cap cover. The bottle cap includes a proximal handling portion and a stem that extends from the proximal handling portion to a distal end. The stem has opposing outside and inside surfaces. The outside surface includes a sealing feature for sealing to the mouth of a beverage bottle. The inside surface defines an opening extending to the distal end of the stem. The shell has an inside surface defining a cavity that is closed at a distal end. A pin extends from the distal end of the inside surface of the shell. The pin is received into the opening of the stem to provide a holding force to secure the bottle cap cover to the bottle cap.
