There are full ranges of manual, semi-automatic and automatic coffee machines available. Manual models are designed for occasional use and would suit a small business.
Semi-automatic machines need dispense staff to be well-trained on machine operation to provide coffee with the best flavour and the trademark creamy topping on espresso (manufacturers offer training packages with the sale of a machine). Fully automatic machines require less operator skill, but staff members still require proper training.
Both types are designed for continual use and are commonly found in specialist coffee shops. The two main advantages of automatic machines are that they deliver quality with consistency and speed.
Smart, shiny, well kept machines that are prominently displayed will boost sales as coffee is a "lifestyle product".
