The present invention relates to a coffee beverage comprising a high yield coffee (HYC) infused with nitrogen thus producing a refreshing cold foamy and creamy beverage; wherein HYC represents liquid coffee having anhydrocarbohydrate content between 25 and 42% w/w.

The present invention relates to a liquid coffee beverage comprising liquid coffee infused with nitrogen thus producing a refreshing cold foamy and creamy beverage.

The present invention relates to a liquid coffee beverage comprising liquid coffee infused with nitrogen thus producing a refreshing cold foamy and creamy beverage.

The present invention provides a method for the manufacture of a freeze-dried coffee powder, the method comprising: providing a coffee extract having from 40 wt % to 55 wt % solids; adding gas to the coffee extract in an amount of from 1 NL/kg to 5 NL/kg of coffee extract, to provide a gas-containing coffee extract at above atmospheric pressure; depressurising the gas-containing coffee extract to form a foamed coffee extract; cooling the foamed coffee extract to below ?40? C. without shear, or with low shear, to form a frozen coffee extract, grinding the frozen coffee extract to a powder; and drying the powder, wherein the step of cooling the foamed coffee extract to below ?40? C. comprises: (i) cooling the foamed coffee extract to a first temperature; (ii) cooling the foamed coffee extract from the first temperature to a second temperature lower than the first temperature; and (iii) cooling the foamed coffee extract from the second temperature to below ?40? C., wherein the first temperature is 1? C. above a freezing point of the foamed coffee extract and wherein the second temperature is 3? C. below the freezing point, wherein step (ii) has a duration of from 5 to 90 minutes, preferably 10 to 60 minutes.
