A tea spirit and a method for preparing the same are provided. The method comprises steps crushing tea leaves and soaking the crushed tea leaves in a solvent to obtain a tea suspension; subjecting the tea suspension to distillation under reduced pressure to obtain a tea aroma extract and a remaining tea pulp; filtering the tea pulp to obtain a tea soup, and subjecting the tea soup to concentration under reduced pressure and filtering the tea soup to obtain a filtrate; adsorbing the filtrate with macroporous adsorption resin, then adding food-grade anhydrous alcohol, letting the resultant mixture stand, separating solid from the mixture and drying the solid to obtain a tea theanine extract; and mixing the tea aroma extract and the tea theanine extract with Chinese baijiu to obtain the tea wine. The tea wine as obtained has both tea aroma and wine aroma, and also has an improved intoxication tolerance time.

A recirculation brewing process and apparatus for performing the same are disclosed. In some embodiments, the coffee brewing process comprises: a brew chamber to hold a packed chamber of coffee grounds; and a pump to force a liquid under pressure through the packed chamber of coffee grounds to extract coffee flavor from the coffee grounds into the liquid using acoustic cavitation.

The present disclosure relates to the technical field of tea brewing devices, and more particularly, to a beverage brewing device. The beverage brewing device comprises a kettle body, a heating disc, and a tea-leaf basket. The heating disc and the tea-leaf basket are located in the kettle body and an air cylinder mechanism is fixed in the kettle body. A moving piston is arranged in an inner cavity of the air cylinder mechanism, and the piston is connected to the tea-leaf basket. The air cylinder mechanism is connected to an air pump, which is used for conveying a driving gas to the air cylinder mechanism. The piston is driven by the driving gas, thereby driving the tea-leaf basket to move in the kettle body. The air cylinder mechanism may automatically drive the tea-leaf basket to move up and down, achieving a simple structure and a low cost.
