A method for controlling an automatic coffee bean grinder (2) which is separate from an automatic coffee brewing machine (1) using ground coffee produced by said coffee bean grinder (2), is shown, wherein a flowmeter sniffer element (15) is located in or at a housing (3) of said coffee brewing machine (1) is capturing the water flow-through information measured by a water flowmeter (5) of said coffee brewing machine (1), and transmits the water flow-through information to a grinder control unit (26) located in the automatic coffee bean grinder (2), and the grinder control unit (26) controls the grinder module (24) as a function of the water flow-through information transmitted from said flowmeter sniffer element (15).

Provided is a heat-sterilized and packed beverage containing a high concentration of a medium chain triglyceride (MCT) and obtained by heat sterilization, wherein issues of poor aftertaste and throat discomfort caused by a combination of a high concentration of the MCT and heat sterilization are resolved. The heat-sterilized and packed beverage is obtained by causing 10-120 mg/100 ml of caffeine to coexist with a beverage containing 1.2-32 g/100 ml of the MCT.

A machine for preparing coffee beverages comprises an infusion unit comprising an infusion chamber suitable to contain a quantity of coffee powder to be subjected to infusion, a grinding unit to grind coffee beans and obtain coffee powder, a water tank connected to the grinding unit, means for feeding and heating the water, and a dispensing unit fluidically connected to the infusion unit and configured to dispense the beverage prepared into a receptacle. The invention also concerns a method to regulate a machine for preparing coffee beverages.

According to the present disclosure, when drip coffee is extracted, it may learn drip coffee recipe information of a barista to be imitated and extract the drip coffee based on the learned reference acidity and reference concentration. The extracted drip coffee may be compared with the learned reference acidity and the reference concentration and evaluated, and when the acidity and concentration of the drip coffee are matched with the reference acidity and the reference concentration, the drip coffee having the same acidity and concentration as the drip coffee may be extracted. Alternatively, when the acidity and concentration of the drip coffee are not matched with the reference acidity and the reference concentration, drip coffee having the same or/and similar acidity and concentration as or/and to the reference acidity and the reference concentration may be extracted by changing extraction conditions of the drip coffee through reinforcement learning.
