The last types of machine to consider if offering a "real" coffee are the ones that have been familiar for many years. Filter type coffee made with Pre ground coffee. The type of machines depends upon volumes required. For example, high volumes of coffee may be required for breakfast coffees in Hotels. Conference Centres would require high volumes for seminar coffee breaks. Also, Function facilities, Staff canteens and Theatres where a high demand for fresh coffee is required in a short space of time.
After the initial purchase of a single serve coffee machine which ranges in price from $85 to $190, the cost per cup of coffee is much less than that of a cup of coffee from a gourmet coffeehouse. The average cost per cup of coffee is anywhere from $0.65 to $1.25 with a Keurig coffee machine. Compare this to upwards of $5.00 per cup at a coffeehouse. You will save a lot of money with the single serve coffee brewer.
If you work in a small office, a machine with a small carafe is sufficient. However, you work in a very large office, a machine that can fill a large coffee urn might be what is needed. Another feature that would be useful in this type of environment is a machine with a "time to clean" indicator coupled with a self clean feature. Often, calcium buildup can occur in these machines and an indicator of when the machine needs to be cleaned is important. In a shared environment, it is very likely that responsibilities like cleaning the coffee machine can be ignored due to the phenomenon known as the tragedy of the commons. By having a machine with simplified cleaning measures like an auto-clean, you can avoid the pitfall of nobody taking responsibility to clean.
