Homebrewing equipment includes essential tools and supplies needed to brew beer at home. Key items are a brew kettle for boiling ingredients, a fermenter for allowing the beer to ferment, and a bottle filler for packaging the finished product. Additional equipment may include a thermometer, hydrometer, and sanitizer to ensure cleanliness and proper fermentation. Other important components are bottles or kegs for storage, as well as airlocks to allow gases to escape during fermentation while preventing contamination. Homebrewers may also use a mash tun for all-grain brewing, which helps extract sugars from grains for fermentation.
