A brewing kettle is a large pot used in the process of making beer. It is designed to hold water and malted grains, allowing them to be heated together. This process, known as mashing, helps extract sugars from the grains, which are essential for fermentation. Brewing kettles can be made from various materials, including stainless steel and aluminum, and often come with a lid to maintain temperature. After mashing, the mixture is boiled in the kettle, where hops are added for flavor and aroma. The boiling process also sterilizes the liquid, known as wort, preparing it for fermentation with yeast. Many brewing kettles are equipped with features like temperature gauges and spigots for easy pouring.
