Siphon coffee, also known as vacuum coffee or syphon coffee, is a unique brewing method that involves using a glass or metal apparatus. The process involves heating water in a lower chamber and creating a vacuum that draws the water up through a tube and into an upper chamber containing coffee grounds. The coffee is brewed under precise temperature and timing conditions, resulting in a rich, smooth, and flavorful cup of coffee with no sediment or bitterness. Siphon coffee is often praised for its clarity and complexity of flavor, and the theatrical process of brewing can add a fun and impressive element to any coffee experience.
