Single serve capsule for producing coffee beverages with and without crema

Abstract

This invention relates to a single serve capsule for producing a coffee beverage. The single serve capsule has a capsule base body, in which a textile fabric and a beverage substance are arranged, said beverage substance being provided in the single serve capsule in order to be stored and to be extracted from said capsule through the textile fabric by means of pressurised hot water. The beverage substance is substantially in powder form and comprises roasted, ground coffee, the roasted coffee having a colour value from 50 to 150.

1 . A single serve capsule for producing a coffee beverage,

         2 . The single serve capsule as claimed in  claim 1 , wherein the textile fabric has an air permeability in the range from 50 to 4000 l/(m 2 s). 
     
     
         3 . The single serve capsule as claimed in  claim 1 , wherein the beverage substance is present in the single serve capsule in an amount in the range from 4 to 11 g. 
     
     
         4 . The single serve capsule as claimed in  claim 1 , wherein the beverage substance is substantially pulverulent, comprises roasted, ground coffee which in the dry state has a D[4,3] value in the range from 200 to 500 μm. 
     
     
         5 . The single serve capsule as claimed in  claim 1 , wherein the capsule base is partially open or closed. 
     
     
         6 . The single serve capsule as claimed in  claim 1 , wherein the textile fabric has an air permeability in the range from 100 to 600 l/(m 2 s). 
     
     
         7 . The single serve capsule as claimed in  claim 6 , wherein the textile fabric has a weight per unit area in the range from 400 to 1500 g/m 2 . 
     
     
         8 . The single serve capsule as claimed in  claim 6 , wherein the capsule base is partially open. 
     
     
         9 . The single serve capsule as claimed in  claim 6 , wherein the coffee beverage does not have a crema. 
     
     
         10 . The single serve capsule as claimed in  claim 1 , wherein the textile fabric has an air permeability in the range from 1800 to 2200 l/(m 2 s). 
     
     
         11 . The single serve capsule as claimed in  claim 10 , wherein the textile fabric has a weight per unit area in the range from 20 to 120 g/m 2 . 
     
     
         12 . The single serve capsule as claimed in  claim 10 , wherein the capsule base is closed. 
     
     
         13 . The single serve capsule as claimed in  claim 10 , wherein the coffee beverage has a crema. 
     
     
         14 . The single serve capsule as claimed in  claim 1 , wherein the achievable beverage volume is in the range from 20 to 170 ml.
