2. A ground coffee bean product according to claim 1 , wherein the product has a moisture content of less than 6%.
3. A ground coffee bean product according to claim 2 , wherein the coffee bean particles are particles of roasted coffee beans.
4. A ground coffee bean product according to claim 3 , wherein the product has an Agtron scale score of between 20 and 90.
5. A ground coffee bean product according to claim 1 , wherein the product comprises between 0.88% and 1.56% (w/w) paraxanthine.
6. A ground coffee bean product according to claim 5 , wherein the product comprises 0.1% (w/w) caffeine or less.
7. A ground coffee bean product according to claim 6 , wherein the product comprises between 0.96% and 1.44% (w/w) paraxanthine.
8. A method of producing a ground coffee bean product according to claim 1 , comprising:
(i) admixing solid paraxanthine and coffee bean particles to form the admixture, or
(ii) admixing solid paraxanthine and unground coffee beans and grinding the admixture to form coffee bean particles,
wherein
