Abstract: A stackable glass having a bowl with a rim and a partially hollow base formed by a wall coupled to the bowl opposite the rim. A central structure is arranged in the partially hollow base that extends away from the bowl. The central structure and tapers toward the wall of the partially hollow base to define an annular moat surrounding the central structure. There is at least one vent passing through the wall of the partially hollow base arranged in the partially hollow base proximate to a point at which the central structure meets the wall of the partially hollow base that provides a passage between an inside of the partially hollow base and an outer surface of the stackable glass.

Abstract: A stackable liquor glass has a bowl and a stem with set of equidistantly spaced holes to reduce vacuum pressure. In addition the stackable liquor glass includes a drainage passage, vented by the equidistantly placed holes for passage of fluid and air through a drainage pathway. The drain passage drains fluid through an asymmetric pathway for drainage outside of the glass through an opening in the glass. In addition a flat surface inside the bowl of the glass provides for a structure for the stacked glass to rest upon.
