This is possible by knowing the specific gravity of each product poured inside of the glass: the heavier ingedient must be poured first on the bottom of the glass; subsequently the other ingredients, progressively lighter, must added in the the most delicate way, often is used a bar spoon to reduce the intensity of the flow of the liquid, or the liquid is poured against the edge of the glass.
