Abstract

Liquid brewed beverage concentrates and methods of making the concentrates are provided herein. The concentrates are liquid and flowable at room temperature and can be diluted in an aqueous liquid to provide a beverage having the general appearance, flavor, and aroma of a freshly brewed beverage. The concentrates include a low water content, high non-aqueous liquid content, particularly non-volatile non-aqueous liquid content, and high flavor solids content, the amounts of which are balanced to provide concentrates with a desired flavor profile with little or no flavor degradation after storage at room temperature in a sealed container for at least about three months.

First claim

What is claimed is:

1. A liquid coffee beverage concentrate comprising:
about 50 to about 90 percent non-aqueous liquid, the non-aqueous liquid comprising at least one of the group consisting of glycerol, propylene glycol, 1,3-propanediol, polyethylene glycol, polyglycerol, and polyglycerol ester;
less than about 30 percent water and volatile non-aqueous liquid; and
about 10 to about 70 percent coffee solids,
the liquid coffee beverage concentrate being a non-gaseous, flowable, fluid composition at room temperature.

2. The liquid coffee beverage concentrate of claim 1 , wherein the non-aqueous liquid comprises non-volatile non-aqueous liquid in amount exceeding or equal to the amount of water and volatile non-aqueous liquid in the concentrate.

3. The liquid coffee beverage concentrate of claim 1 , wherein the concentrate comprises about 50 to about 90 percent non-volatile non-aqueous liquid.

4. The liquid coffee beverage concentrate of claim 3 , wherein the non-volatile non-aqueous liquid comprises at least one of the group consisting of glycerol, propylene glycol, and 1,3-propanediol.

5. The liquid coffee beverage concentrate of claim 1 , wherein the concentrate includes less than about 20 percent by weight volatile non-aqueous liquid and water.

6. The liquid coffee beverage concentrate of claim 5 , wherein the amount of water and volatile non-aqueous liquid is less than or equal to the amount of non-volatile non-aqueous liquid.

7. The liquid coffee beverage concentrate of claim 1 , wherein the coffee solids are selected from the group consisting of ground coffee beans, freeze-dried coffee, spray-dried coffee, instant coffee powder, ground roast coffee beans, and combinations thereof.

8. The liquid coffee beverage concentrate of claim 7 , wherein the coffee solids comprise ground roast coffee beans.

9. The liquid coffee beverage concentrate of claim 1 , wherein the non-aqueous liquid comprises non-aqueous liquid sourced from at least one of coffee beans, coffee cherries, spent coffee grounds, and coffee oil.

10. The liquid coffee beverage concentrate of claim 1 , wherein the total amount of water and volatile non-aqueous liquid in the concentrate is less than or equal to the total solids content of the concentrate.

11. The liquid coffee beverage concentrate of claim 1 , wherein the concentrate comprises about 25 to about 60 percent coffee solids.

12. The liquid coffee beverage concentrate of claim 1 , wherein the concentrate includes less than about 20 percent water and volatile non-aqueous liquid.

13. The liquid coffee beverage concentrate of claim 1 , wherein the coffee solids are selected from the group consisting of freeze-dried coffee, spray-dried coffee, instant coffee powder, and combinations thereof.

14. A liquid coffee beverage concentrate comprising:
about 50 to about 90 percent non-aqueous liquid, the non-aqueous liquid comprising at least one of the group consisting of glycerol, propylene glycol, 1,3-propanediol, polyethylene glycol, polyglycerol, and polyglycerol ester;
less than about 30 percent water and volatile non-aqueous liquid; and
about 10 to about 70 percent coffee solids, the coffee solids selected from the group consisting of ground coffee beans, freeze-dried coffee, spray-dried coffee, instant coffee powder, ground roast coffee beans, and combinations thereof,
wherein a total weight of water-soluble solids exceeds a total weight of water-insoluble solids dispersed and/or suspended in the coffee beverage concentrate,
the liquid coffee beverage concentrate being a non-gaseous, flowable, fluid composition at room temperature.

15. The liquid coffee beverage concentrate of claim 14 , wherein the non-aqueous liquid comprises non-volatile non-aqueous liquid in amount exceeding or equal to the amount of water and volatile non-aqueous liquid in the concentrate.

16. The liquid coffee beverage concentrate of claim 14 , wherein the concentrate comprises about 50 to about 90 percent non-volatile non-aqueous liquid.

17. The liquid coffee beverage concentrate of claim 14 , wherein the non-volatile non-aqueous liquid comprises at least one of the group consisting of glycerol, propylene glycol, and 1,3-propanediol.

18. The liquid coffee beverage concentrate of claim 14 , wherein the concentrate includes less than about 20 percent by weight volatile non-aqueous liquid and water.

19. The liquid coffee beverage concentrate of claim 14 , wherein the amount of water and volatile non-aqueous liquid is less than or equal to the amount of non-volatile non-aqueous liquid.

20. The liquid coffee beverage concentrate of claim 14 , wherein the coffee solids comprise ground roast coffee beans.

21. The liquid coffee beverage concentrate of claim 14 , wherein the total amount of water and volatile non-aqueous liquid in the concentrate is less than or equal to the total solids content of the concentrate.

22. The liquid coffee beverage concentrate of claim 14 , wherein the concentrate comprises about 25 to about 60 percent coffee solids.

23. The liquid coffee beverage concentrate of claim 14 , wherein the concentrate includes less than about 20 percent water and volatile non-aqueous liquid.

24. The liquid coffee beverage concentrate of claim 14 , wherein the coffee solids are selected from the group consisting of freeze-dried coffee, spray-dried coffee, instant coffee powder, and combinations thereof.
