A beer glass (10) comprises a base (12) and side wall (14). A minor part of the base (12) e.g. an annular region (16) at the junction between the base (12) and side wall (14) is treated e.g. by sand blasting or laser etching. In use, pouring of a carbonated beverage of a relatively high carbon dioxide content (e.g. about 1.3 - 1.5 volumes) induces the evolution of bubbles in a controlled manner in the beverage, by contact of the beverage with nucleation sites produced in the sand blasted region or laser etched region (16). The method tends to induce evolution of bubbles in a controlled manner in the beverage. <IMAGE> |
