A Brew Kettle is a key piece of equipment used in the beer brewing process. It is where the wort, a mixture of water and malted grains, is boiled. This step is crucial as it helps extract flavors and aromas from the hops, which are added during the boil. The kettle is typically made of stainless steel to withstand high temperatures and prevent contamination. After boiling, the wort is cooled and transferred to a fermentation vessel, where yeast is added. This process leads to the production of alcohol and carbonation, resulting in the final product, beer. Brew kettles come in various sizes, catering to both home brewers and commercial breweries.
