A beverage container or package that includes an internal surface for promoting nitrogen bubble nucleation and growth. The surface incorporates a plurality of nanoscale structures, e.g. between 6 and 100 nanometres in size. Most preferably the structures are pits, greater than 15 nm in depth/height. Upon opening the container filled with a Nitrogen (and carbon dioxide) supersaturated beverage, a foaming effect occurs which provides a desirable head of fine bubbles when transferred to a drinking glass. |
