Glugging (also referred to as "the glug-glug process"[1]) is the physical phenomenon which occurs when a liquid is poured rapidly from a vessel with a narrow opening, such as a bottle.[2][3] It is a facet of fluid dynamics.

Uncorking and pouring
Uncorking, first pour, and re-corking of a 70cc bottle of Bourbon whiskey. During the pour, glugging can be heard.
As liquid is poured from a bottle, the air pressure in the bottle is lowered, and air at higher pressure from outside the bottle is forced into the bottle, in the form of a bubble, impeding the flow of liquid.[3] Once the bubble enters, more liquid escapes, and the process is repeated.[3] The reciprocal action of glugging creates a rhythmic sound.[4] The English word "glug" is onomatopoeic, describing this sound.[5] Onomatopoeias in other languages include Gluckern (German).
Factors which affect glugging are the viscosity of the liquid, its carbonation, the size and shape of the container's neck and its opening (collectively referred to as "bottle geometry"), the angle at which the container is held, and the ratio of air to liquid in the bottle (which means that the rate and the sound of the glugging changes as the bottle empties).[3][4][7]
