Vietnam has a unique way of brewing coffee called “phin”. First, a perforated metal filter plate is placed on top of a glass or mug. A few tablespoons of finely ground beans are added to the reusable metal brew chamber, which sits on the filter plate. A gravity chamber is pressed down on top of the coffee, before hot water is poured over top. This process allows the coffee to slowly drip downward into the glass, enhancing its flavour.
