Apparatus, systems and methods for dispensing drinks

An apparatus for dispensing a first liquid comprising a second liquid, the apparatus comprising:

• a male coupling configured to enter and establish a friction seal with a female coupling of a container containing the second liquid by inserting the male coupling into the female coupling and applying a load to the male coupling, the load being provided by the weight of a portion of the apparatus;
• a spout;
• and a pump for causing the second liquid to exit the container and the first liquid to be dispensed via the spout after the friction seal is established between the female and male couplings;
• wherein the male coupling is V-shaped, and thus configured to enter and establish a friction seal with a V-shaped female coupling;
• comprising a first carbon dioxide level sensor strip configured to connect with a second carbon dioxide level sensor strip of the container when the friction seal is established between the V-shaped female coupling of the container and the V-shaped male coupling of the apparatus.
