Process of brewing tea leaves contained in a capsule
View Patent ↗The invention concerns a process for the preparation of a beverage in a beverage machine with a capsule comprising an enclosure containing tea leaves comprising the steps of: a) introducing water in the capsule to submerge the tea leaves in the capsule enclosure, then b) introducing water at a soaking flow of at most 80 ml/min, then c) introducing water in the capsule until the required volume of beverage is delivered, wherein during at least one period of step b), water is introduced in the capsule at least once at a stirring flow superior the soaking flow to stir tea leaves.
1. Process for the preparation of a beverage in a beverage machine using a capsule comprising an enclosure containing tea leaves comprising the steps of:
a) introducing water into the capsule to submerge the tea leaves in the capsule enclosure;
b) introducing water at a soaking flow between 20 and 80 ml/min;
c) introducing water in the capsule until a required volume of beverage is delivered; and
during at least one period of step b), water is additionally introduced into the capsule at a stirring flow greater than the soaking flow to stir tea leaves.
2. Process according to claim 1 wherein during step a), water is introduced at a flow of at least 150 ml/min.
3. Process according to claim 1 , wherein during step b), the soaking flow is null.
4. Process according to claim 1 , wherein the length of time of the at least one period during which water is introduced into the capsule at a stifling flow greater than the soaking flow to stir tea leaves is less than 5 seconds.
5. Process according to claim 1 , wherein the length of time of step b) is at least 5 seconds.
6. Process according to claim 1 , wherein during step b) the stifling flow is at least greater than 150 ml/min.
7. Process according to claim 1 , wherein during step c), water is introduced at a flow of at least 150 ml/min.
8. Process according to claim 1 , wherein water is introduced at a temperature of between 30 and 95° C.
9. Process according to claim 1 , wherein the capsule further comprises
a filtering wall defining at least one filtering side of the enclosure, and
an overflow wall that is located in a path of the brewed liquid after the filtering wall and which comprises at least one overflow aperture.
10. Process according to claim 1 , wherein the filtering wall extends from below a median horizontal plane passing through the enclosure when the capsule is positioned so that the overflow aperture is located above the plane.
11. The process according to claim 1 , wherein step c) comprises filling the capsule with hot water first at a flow of 150 ml/min and then rapidly at a flow of 225 ml/min until the total desired volume of tea beverage flows through the capsule outlet and fills the cup.
12. The process according to claim 1 , wherein step b) comprises an additional soaking flow after the stirring flow.
