1. A glass bottle comprising a neck, a shoulder and a body; a sealable opening at the end of or above the neck and comprising optionally a finish, wherein the bottle comprises a hydrophobic layer, coating or film, formed within or on a surface of the glass of at least in part the inner surface of the neck or shoulder of the bottle, said hydrophobic layer, coating or film, constituting an anti-gushing zone, inhibiting or preventing a gushing of a carbonated aqueous liquid when or at opening of said bottle filled with said carbonated aqueous liquid, that part of said hydrophobic layer, coating or film contactable with a surface of said carbonated aqueous liquid constituting an anti-gushing zone wherein the anti-gushing zone within or on the surface of the glass inside the bottle of the present invention does not cover the entire inner surface of the glass bottle, wherein the bottle is filled with a carbonated alcoholic beverage comprising living yeast. 2. The glass bottle according to claim 1, wherein the anti-gushing zone within or on the surface of the glass inside the bottle is in such portion of the inner bottle surface such that in the closed bottle, filled with carbonated beverage while standing or while lying, at least that part of the surface is hydrophobic which contacts the edge of the surface of the stored carbonated beverage. 3. The glass bottle according to claim 1, wherein the finish of said bottle does not comprise the anti-gushing zone. 4. The glass bottle according to claim 1, wherein the hydrophobic zone is localized so that when the container is filled by the carbonated aqueous liquid, the edge of the liquid surface contacts the hydrophobic zone and the hydrophobic zone is at least 5 mm above the edge of the liquid surface and at least 5 mm under the edge of the liquid surface. 5. The glass bottle according to claim 1, wherein the hydrophobic zone is localized so that when the container is filled by the carbonated aqueous liquid, the edge of the liquid surface contacts the hydrophobic zone and the hydrophobic zone is less than 2 cm above the edge of the liquid surface and at least 5 mm under the edge of the liquid surface. 6. The glass bottle according to claim 1, wherein the hydrophobic zone is localized so that when the container is filled by the carbonated aqueous liquid, the edge of the liquid surface contacts the hydrophobic zone and the hydrophobic zone is at least 1 cm above the edge of the liquid surface and at least 1 cm under the edge of the liquid surface. 7. The glass bottle according to claim 1, wherein the hydrophobic zone is localized at least 1 cm under the cap of the bottle. 8. The glass bottle according to claim 1, wherein the anti-gushing zone or the hydrophobic zone comprises polyethylene, poly(vinyl chloride), poly(vinylidene fluoride) or chlorinated polypropylene or surface treatment with glycidyloxypropyl-trimethoxysilane. 9. The glass bottle according to claim 1, wherein the anti-gushing zone or the hydrophobic zone comprises polydialkylsiloxane, polyalkylsiloxane, poly-diphenylsiloxane or polymethylphenylsiloxane; or surface treatment with dialkyldichlorosilane, alkyldichlorosilane, highly reactive oligosiloxysilane, oligosiloxysiloxane, polydimethylsiloxane, dimethyldimethoxysilane, dimethyl-dichlorosilane or diacetoxydimethylsilane. 10. The glass bottle according to claim 1, wherein the carbonated alcoholic beverage comprising living yeast is a beer. 11. The glass bottle according to claim 10, wherein the carbonated alcoholic beverage comprising living yeast is a top-fermented beer. 12. The glass bottle according to claim 1, wherein the carbonated alcoholic beverage comprising living yeast is a sparkling wine or champagne. 13. The container according to claim 1, wherein said inner hydrophobic zone is manufactured in the bottle by a spraying, a dipping, or a contact application method. 14. The container according to claim 1, wherein said inner hydrophobic zone obtainable by dipping said finish, neck or shoulder in a solution containing a hydrophobic coating or in a hydrophobic treatment liquid over a vent to achieve inflow of said solution or liquid into the bottle. 15. The glass bottle according claim 1, wherein the anti-gushing zone comprises a hydrophobic thin layer, a hydrophobic thin film, an ultrathin hydrophobic layer or an ultrathin hydrophobic film formed within or on the surface of the glass of at least part of the internal surface of said bottle. 16. The glass bottle according to claim 1, wherein the anti-gushing zone can be formed by the hydrophobic coating or by a layer of deposited hydrophobic treatment composition. 17. The glass bottle according to claim 1, wherein the anti-gushing zone is formed within or on the surface of the glass as a fixed layer, a fixed coat or a fixed film. 18. The glass bottle according to claim 17, wherein the fixed anti-gushing zone formed is not loosenable or is not detachable and is not a removable, not a re-introducible or not a replaceable plug, sprout, crown, cap or stem, for instance to prevent liquid dripping during a pouring action into a cup.
