Carbonated beverage nucleation accessory

A method comprising:

• pouring a beer into a beverage container, wherein a carbon dioxide gas is dissolved within the beer;
• placing a nucleation accessory into the beer within the beverage container, wherein the nucleation accessory includes a body that includes top and bottom surfaces and a rounded outer surface that extends around an axis between the top and the bottom surfaces, wherein the body includes a bore extending completely through the body from the top surface to the bottom surface along the axis, at least one recess in the rounded outer surface of the body, and at least one recess formed on a surface of the bore facing the axis, and wherein the carbon dioxide gas attaches to the at least one recess in the rounded outer surface of the body and to the at least one recess on the surface of the bore facing the axis;
• and
• generating, by the at least one recess in the rounded outer surface of the body and the at least one recess on the surface of the bore facing the axis, bubbles within the beer due to gas bubble nucleation to generate a head of foam.

A method comprising:

• submerging a nucleation accessory within a carbonated beverage, wherein the nucleation accessory includes a body that includes a top surface, a bottom surface, an outer surface that extends between the top surface and the bottom surface and around an axis, and a bore that extends completely through the body between the top surface and the bottom surface along the axis, and wherein the outer surface includes a plurality of recesses within the outer surface at a depth of 0.025-0.063 centimeters, and wherein carbon dioxide dissolved in the carbonated beverage attaches to the plurality of recesses;
• and
• generating, by the plurality of recesses, bubbles within the carbonated beverage due to gas bubble nucleation, wherein the plurality of recesses in the outer surface includes a zigzag line that extends circumferentially around an entirety of the outer surface, a first plurality of diamond shaped lines etched in the outer surface between the zigzag line and the top surface, and a second plurality of diamond shaped lines etched in the outer surface between the first plurality of diamond shaped lines and the top surface,
• wherein the bore further includes a plurality of recesses on a surface thereof facing the axis, such that bubbles are also generated within the carbonated beverage due to gas bubble nucleation by the plurality of recesses on the surface of the bore facing the axis.
