[ What is claimed is:] [1.] A coffee extract manufacturing method comprising the step of adding a strong alkaline salt to a coffee extract to modulate hydrogen ion concentration, in an amount to prevent precipitation or deterioration of the flavor resulting from long preservation and, at the same time, when said extract is filled into a sealed container, preventing occurrence of gas resulting from passage of time or heat sterilization which can cause expansion, deformation and breakage of the container.
