1. A drinking vessel adapted to receive ground coffee and hot water for brewing coffee so that the brewed coffee may be drunk from the vessel, comprising: a base section having a first chamber; and,a pump member adapted for an operable communication with the base section so that the pump member is slidably moveable upwardly and downwardly relative to the base section; the pump member comprising a hand operated piston operable in the first chamber and arranged to fit closely within the first chamber of the base section;sidewall parts defining a plurality of apertures;a shroud adapted to form an outer surface of the drinking vessel; and,a filter located at a base of the first chamber;wherein the hand operated piston divides the first chamber into the first chamber below the piston and a second chamber above the piston as the piston is urged downwardly in use;whereinthe base section further comprises an outer part with an outer wall and an inner part with an inner wall, the outer wall and the inner wall defining a third chamber arranged to convey brewed coffee from the first chamber into the second chamber via the plurality of apertures of the pump member as the piston is urged downwardly in use; and,the shroud overlies the outer wall of the outer part of the base section. 2. The drinking vessel of claim 1, whereas the plurality of apertures are slits which extend longitudinally along substantially the length of the pump member. 3. The drinking vessel of claim 1, wherein the shroud extends the length of the pump member. 4. The drinking vessel of claim 1, wherein the outer part comprises a base wall and a tubular outer wall, the tubular outer wall having an upper region:the inner part comprises a tubular inner wall with an upper region, the upper region of the inner part including a plurality of spacers defining a plurality of inner part apertures therebetween; and,as the piston is urged downwardly, brewed coffee flows from the third chamber through the plurality of inner part apertures and into the second chamber. 5. The drinking vessel of claim 4, wherein the tubular outer wall has a threaded upper region:the tubular inner wall has a lower region and a threaded upper region; and,the threaded upper region of the inner part being adapted to be threaded into engagement with the threaded upper region of the outer part. 6. The drinking vessel of claim 4, wherein the upper region of the inner part extends radially outwardly away from the tubular inner wall. 7. The drinking vessel of claim 4, wherein the lower region of the inner part includes a removable flow control means. 8. The drinking vessel of claim 7, wherein the lower region of the inner part comprises retaining protrusions adapted to hold the flow control means in place when twisted into position. 9. The drinking vessel of claim 7, wherein the filter is located on the flow control means and positioned securely between the flow control means and the lower region of the inner part when the flow control means is connected to the lower region of the inner section. 10. The drinking vessel of claim 7, wherein the flow control means comprises: a ring part;a plurality of spokes extending inwardly from the ring part; and,a plurality of fins depending from the spokes, the fins defining a plurality of angled outlets adapted to cause mixing of liquid as it passes through the flow control means. 11. A method of brewing coffee, comprising the successive steps of: obtaining the drinking vessel of claim 1;putting ground coffee into the first chamber of the base section;introducing hot water into the base section;allowing the water to pass through the ground coffee until liquid levels in the first and third chambers are in equilibrium; and,operating the piston to pump water remaining in the first chamber through the coffee into the third chamber, the operating including conveying the brewed coffee through the plurality of apertures. 12. The method of claim 11, wherein brewed coffee is conveyed from the third chamber to the second chamber. 13. The method of claim 11, wherein the filter remains stationary relative to the base section. 14. The method of claim 11, wherein the pump member moves relative to the filter. 15. The method of claim 11, wherein the steps of (i) allowing water to pass through the ground coffee extracts soluble material from the coffee; and,(ii) pumping water through the coffee extracts non soluble oils to form an emulsion. 16. The drinking vessel of claim 10, wherein the fins are arranged to contact the base wall of the outer part.
