The present invention provides a cartridge for a beverage preparation system, the cartridge comprising an inlet for the introduction of an aqueous medium into the cartridge, an outlet downstream of the inlet for the discharge of a beverage from the cartridge and a flow path connecting the inlet to the outlet, wherein the flow path includes within it a non-gelled beverage liquid concentrate containing about 0.01 to about 5 weight % in total of one or more thickeners. The cartridge may comprise an aperture having a cross-sectional area of 2 mm2 or less downstream of a chamber in which the beverage liquid concentrate is loaded. The beverage concentrate may comprise methyl cellulose and at least one alginate in a weight ratio of 1:5 to 5:1 to provide improved the organoleptic properties such as mouthfeel.

1. A sealed cartridge for a beverage preparation system for producing a brewed beverage, the sealed cartridge comprising: an inlet for the introduction of an aqueous medium into the cartridge,an outlet downstream of the inlet for the discharge of the brewed beverage from the cartridge,a flow path connecting the inlet to the outlet, the flow path comprising a first cross-sectional area greater than a second cross-sectional area downstream of the first cross-sectional area,a beverage liquid concentrate in the flow path upstream from the second cross-sectional area, the beverage liquid concentrate comprising a liquid concentrate and an alginate and/or a thermally reversible gelling thickener, and the total concentration of the thickener in the beverage liquid concentrate is about 0.01 to about 5 weight %, andthe one or more thickeners configured to provide delayed thickening so that the beverage liquid concentrate is non-gelled when in the sealed cartridge but capable of flowing through the second cross-sectional area and thickening the brewed beverage after introduction of the aqueous medium into the cartridge. 2. The sealed cartridge of claim 1, wherein the reversible gelling thickener is selected from one or more of methyl cellulose and hydroxy propylmethyl cellulose. 3. The sealed cartridge of claim 1, wherein the alginate is selected from one or more of sodium alginate, potassium alginate, and ammonium alginate. 4. The sealed cartridge of claim 1, wherein the beverage liquid concentrate comprises an alginate and methyl cellulose in a weight ratio of about 1:5 to about 5:1, wherein the methyl cellulose and the at least one alginate are present in a combined amount of about 0.01 to about 5 weight %. 5. The sealed cartridge of claim 1 further comprising: a chamber including the beverage liquid concentrate, and the chamber has a cross-sectional area, andan aperture having a cross-sectional area of 2 mm2 or less and less than the cross-sectional area of the chamber downstream of the chamber. 6. The sealed cartridge of claim 1, wherein the liquid concentrate comprises a coffee extract. 7. The sealed cartridge of claim 1, wherein the beverage liquid concentrate comprises an alginate and further comprises a calcium ion sequesterant. 8. The sealed cartridge of claim 1, wherein the thickeners in the beverage liquid concentrate are hydrated in a liquid ingredient. 9. The sealed cartridge of claim 1, wherein the first cross-sectional area is 5 mm2 to 1000 mm2 and the second cross-sectional area is 0.05 mm2 to 2 mm2. 10. The sealed cartridge of claim 1, wherein the first cross-sectional area is 10 mm2 to 500 mm2 and the second cross-sectional area is 0.1 mm2 to 0.5 mm2. 11. The sealed cartridge of claim 1, wherein the first cross-sectional area comprises a chamber including the beverage liquid concentrate and the second cross-sectional area comprises an aperture downstream from the chamber. 12. The sealed cartridge of claim 6, wherein the coffee extract comprises soluble coffee. 13. The sealed cartridge of claim 8, wherein the thickeners in the beverage liquid concentrate are hydrated in the liquid ingredient using a hydration technique comprising at least one of sugar hydration and high shear mixing. 14. A sealed cartridge for a beverage preparation system for producing a brewed beverage, the sealed cartridge comprising: an inlet for the introduction of an aqueous medium into the cartridge,an outlet downstream of the inlet for the discharge of the brewed beverage from the cartridge,a flow path connecting the inlet to the outlet,a chamber comprising a beverage liquid concentrate in fluid communication with the inlet and outlet, the beverage liquid concentrate comprising a liquid concentrate and an alginate and/or a thermally reversible gelling thickener, and the total concentration of the thickener in the concentrate is about 0.01 to about 5 weight %,an aperture downstream from the chamber and having a cross-sectional area less than a cross-sectional area of the chamber,the one or more thickeners configured to provide delayed thickening so that the beverage liquid concentrate is non-gelled when in the chamber but capable of flowing through the aperture and thickening the brewed beverage after introduction of the aqueous medium into the cartridge. 15. The sealed cartridge of claim 14, wherein the chamber's cross-sectional area is 5 mm2 or more and the aperture's cross-sectional area is 2 mm2 or less. 16. The sealed cartridge of claim 14, wherein the chamber's cross-sectional area is 5 mm2 to 1000 mm2 and the aperture's cross-sectional area is 0.05 mm2 to 2 mm2.
