Often known as ‘mustache’ spouts as it resembles the shape of a mustache, the spouts are attached at the bottom of the machine portafilter. Two spouts in a coffee machine allow the brewing of two cups of coffee simultaneously. Almost all coffee espresso machines come with 2 filter baskets. One holds grounded coffee for an individual shot & the other holds coffee for 2 shots. The larger filter basket allows for brewing 2 shots at one go & the mustache spout perfectly dispenses the coffee into two separate cups at once.
