A floating lid is provided which enables the preparation of a beverage of uniform consistency which is retarded in its loss of volatile, oxidation and contamination. The floating lid is buoyant and has an aperture through which the beverage passes. The aperture is surrounded by upwardly-extending walls which form a chamber for the purpose of creating a hydrostatic head of beverage above the aperture.
In a process for preparing brewed coffee and storing the coffee brew in an essentially straight-walled vessel wherein a buoyant lid is placed within the vessel prior to introducing the coffee brew into the vessel, said coffee brew having a soluble solids concentration profile such that the initial portion of brew which is received within the vessel has a higher concentration than the brew which is later received, and wherein the buoyant lid is sized to cover substantially the entire surface of the coffee brew contained in the vessel, the improvement comp...
