Bottle opener, device, server and method for counting beverage consumption

A method for counting beverage consumptions, the method comprising steps of:

• detecting an opening of a beverage bottle by sensing a force applied between a hook and a fulcrum surface of a bottle opener that exceed a predefined threshold, wherein the hook and/or the fulcrum surface is configured to relatively move and/or rotate from a rest position in response of the force applied between the hook and the fulcrum surface exceeding said predefined threshold;
• in response of said detection, capturing an image of the cap by means of an image sensor;
• and
• assigning to said image:
• a device and/or user digital identifier assigned to the bottle opener, an acquisition time, a timestamp, a geographical indication, a geographical coordinate and/or a temperature of the cap and/or of the bottle,
• wherein said step of sensing a force comprises sensing a relative positioning of the hook and/or of the fulcrum surface;
• and
• wherein said step of detecting an opening of a beverage bottle comprises a step of
• determining a first duration of a movement and/or a rotation of the hook or the fulcrum from the rest position;
• and wherein said step of detecting an opening of a beverage bottle comprises a step of
• comparing the first and/or the second duration with a reference duration;
• and/or
• comparing the first duration with the second duration.
