Abstract
The invention relates to a container (1) made of glass or stoneware for a beverage having surface irregularities in a chosen region, the irregularities forming nucleation sites inside the container, the nucleation sites favouring the formation of bubbles in contact with a carbonated beverage, comprising a layer of enamel (10) coating the chosen region, a plurality of enamel grains (12) arranged on the surface of said layer of enamel (10) and attached to said layer of enamel (10), and a hydrophobic compound (13) arranged on a portion of the surface of said enamel grains (12).

A container made of glass or stoneware for a beverage having surface irregularities in a chosen region, the irregularities forming nucleation sites inside the container, the nucleation sites promoting the formation of bubbles in contact with a carbonated beverage, the container comprising:
- an enamel layer coating the chosen region,
- a plurality of enamel grains arranged at the surface of said enamel layer and attached to said enamel layer, and
- a hydrophobic compound arranged on a part of the surface of said enamel grains.
A method for manufacturing a beverage container having surface irregularities in a chosen region, the irregularities forming nucleation sites inside the container, the nucleation sites promoting the formation of bubbles in contact with a carbonated beverage, the method comprising:
- depositing an enamel layer coating the chosen region,
- depositing a plurality of enamel grains on the surface of said enamel layer, and
- cooking the enamel layer whereby the enamel grains are attached to said enamel layer by a same heat treatment, the enamel grains having a hydrophobic compound arranged on a part of the surface of said enamel grains.
