Gooseneck Kettles are a brewing tool used by baristas to help brew pour filter coffee and create more consistent results in doing so. They are useful for brewing pour-over filter coffee but are absolutely non-essential especially if you brew no more than 2 cups of filter coffee daily. They do spark joy for both home and professional baristas though. Gooseneck Kettles are all about controlling the pour of water over the bed of ground coffee within the pour-over brewer. There are four ways that goosenecks work better than regular kettles for baristas.
