A system for heating and frothing a beverage comprises a device for heating and frothing a beverage and a froth wand. The device for heating and frothing a beverage includes a steamer, a steam conduit connecting the steamer to a steam nozzle and a froth wand holder for removably holding a froth wand. The froth wand is a disposable froth wand and comprises a tubular wall having a steam inlet end comprising a steam inlet, a steam outlet end comprising a steam outlet separate from the steam inlet and a steam channel extending between the steam inlet and the steam outlet. The froth wand holder is arranged for holding the disposable froth wand at least in an operational position in the device for heating and frothing a beverage in which operational position the steam nozzle is in communication with the steam inlet of the disposable froth wand.

Consumption of safe beverages improves health, physical performance, and prevents disease. A system includes a device that monitors a beverage within a vessel to determine if the beverage is safe to drink. The device may include a pH sensor to determine a pH value of the beverage. This pH value is compared to a pH range that is deemed safe. A comparison between the pH value and the pH range may be made, and the results presented to a user. The system may include a mixing device to automatically mix the beverage, or the system may prompt a user to manually mix the beverage. Data from other sensors may also be used to assess the beverage. The device may be implemented in various form factors such as a cup, lid, straw, stirrer, and so forth. The device may communicate with other devices, such as a phone, tablet, or server.
