Net-filter coffee
Cà phê vợt (cà phê vợt; also known as net-filter coffee) is a traditional method of brewing coffee in southern Vietnam, associated with cafes in alleys and market-adjacent stalls in Ho Chi Minh City (formerly Saigon). It uses a reusable cloth filter suspended in a metal ring to steep and strain ground coffee into a pot, producing coffee that is brewed in batches and kept warm for pour-out service.
