Coffee brewers with pourover water reservoirs make large quantities of coffee, accommodating more people at a time than single-cup or drip coffee makers. These commercial coffee makers do not require onsite plumbing and only require an outlet to operate. Water must be poured into the reservoir before brewing. These coffee makers can be moved to wherever coffee is needed. They are suitable for use in spaces with high-volume foot traffic such as cafeterias, industrial break rooms, or hotel lobbies. Pourover coffee brewers use filters and grounds to make coffee.
