Abstract

Roast and ground or flaked coffee products which provide more brew strength and cup color at lower levels of brews solids. These coffee products contain darker fasted roasted coffee that is predominantly high acidity-type coffee that provide, when brewed appropriate conditions, a consumable coffee beverage having:

(1) a brew solids level of from about 0.4 to about 0.6%;

(2) a Titratable Acidity of at least about 1.52;

(3) a brew absorbance of at least about 1.25, provided that when the Titratable Acidity is in the range of from about 1.52 to about 2.0, the brew absorbance is equal to or greater than the value defined by the equation:

1.25+ 0.625×(2.0-TA)!

where TA is the Titratable Acidity.

Claims

1. A roast and ground or flaked coffee product having a Hunter L-color of flora about 13 to about 19 and which comprises from about 50 to 100% high acidity-type coffee, from 0 to about 30% low acidity-type coffee, and from 0 to about 50% moderate acidity-type coffee, said coffee product being capable of providing a consumable coffee beverage having:

(1) a brew solids level of from about 0.4 to about 0.6%;

(2) a Titratable Acidity of at least about 1.52;

(3) a brew absorbance of at least about 1.25, provided that when the Titratable Acidity is in the range of from about 1.52 to about 2.0, said brew absorbance value is equal to or greater than the value defined by the equation;

space="preserve" listing-type="equation">1.25+ 0.625×

(2.0-TA)!

wherein TA is the Timtable Acidity.

2. The coffee product of claim 1 which comprises from about 70 to 100% high acidity-type coffee, from 0 to about 20% low acidity-type coffee, and from 0 to about 30% moderate acidity-type coffee.

3. The coffee product of claim 2 which comprises from about 90 to 100% high acidity-type coffee, from 0 to about 10% low acidity-type coffee, and from 0 to about 10% moderate acidity-type coffee.

4. The coffee product of claim 3 which has a Hunter L-color of from about 14 to about 18.

5. The coffee product of claim 4 which has a Hunter L-color of from about 15 to about 17.

6. The coffee product of claim 2 which provides a coffee beverage having Titratable Acidity of from about 1.6 to about 3.0.

7. The coffee product of claim 6 which provides a coffee beverage having Titratable Acidity of at least about 1.58.

8. The coffee product of claim 7 which provides a coffee beverage having Titratable Acidity of from about 1.8 to about 2.7.

9. The coffee product of claim 2 which provides a coffee beverage having a brew absorbance from about 1.3 to about 1.9.

10. The coffee product of claim 2 which provides a coffee beverage wherein when the Titratable Acidity is in the range of from about 1.58 to about 2.2, said brew absorbance is equal to or greater than the value defined by the equation:

space="preserve" listing-type="equation">1.25+ 0.625×

(2.2-TA)!.

11. The coffee product of claim 2 which provides a coffee beverage having a brew solids level of from about 0.42 to about 0.58%.

12. The coffee product of claim 2 wherein said brew absorbance is equal to or greater than the value defined by the equation:

space="preserve" listing-type="equation">2.475- 0.075×

(Hunter L-color of coffee)!.
