A pre-portioned moist product comprising a portion of plant material and a coating is disclosed. Preferably, the plant material comprises tobacco. The coating includes a soluble, non-cross-linkable component and an cross-linkable component which becomes substantially water-insoluble upon crosslinking. The soluble component of the coating dissolves upon placement in the mouth, while the insoluble component disintegrates and/or loses structural integrity once the soluble component has dissolved to release and disperse the plant material in the user's mouth.
