Funnel: A funnel is needed for pouring the wort into the glass carboy. It is also useful when straining or sparging grains.
Airlock (Fermentation Lock): The airlock forms an airtight seal that allows C02 to escape but prevents foreign material from entering the fermenter.
The airlock will be partially filled with water. A carboy will require a stopper.
Capper: A capper is a tool that will attach a cap over the top of the bottle. With a firm squeeze of the capper, a cap will seal taste and carbonation in the beer.
Bottles/Caps: A five-gallon batch of beer yields approximately 2-2 1/2 cases of beer (48-60 bottles). The American Homebrewers Association recommends using brown bottles which may be purchased new, used or recycled. The bottles must be the "pop top" variety, not the twist-off type.
All bottles must be thoroughly sanitized before bottling, and the inside free of any contaminant.
Caps must be purchased new. They come in a bag with more than enough to cap two cases of beer.
Bottle washer (optional): This will speed up cleaning and sterilizing bottles. Attached to the sink, the washer shoots a concentrated spray of water into the bottle.
Sanitizer: An iodine-based sanitizer is recommended over other cleansers. Immersing equipment in an iodine solution will kill any bacteria on the equipment. Antibacterial soap and chlorine bleach are also excellent sanitizers, but the equipment must be rinsed thoroughly after cleaning.
Hydrometer: This instrument measures the alcohol content in beer and determines when a beer is fully fermented and ready to be bottled. The hydrometer measures specific gravity, the thickness of, the density of and the potential alcohol content in a beer.
Brew Kit: For beginning brewers, beer kits include all necessary ingredients to make a five-gallon batch of beer. Most kits come with malt extract, hops, priming sugar and bottle caps.
