serves to create the wort (the unfermented slurry that contains all of the ingredients except for the yeast). The brewing kettle should be large enough to accommodate both the water and other ingredients as well as to account for bubbling that can occur during the brewing process. A general rule of thumb is to purchase a brewing kettle that can hold at least double the amount of beer you are attempting to brew. Next, any beer kit should contain a fermenting container. This container will serve to hold the brew while the yeast does its job. It should be transparent or semi-transparent so that the brewer can monitor the fermentation process. The fermenting container should be accompanied by an airlock, which is a one-way flow device that lets gases escape the fermenting container without allowing impurities to enter. Another necessary device is a hydrometer. This is a small probe that measures the specific gravity of your wort during and after the fermentation process. Since the homebrew process involves both boiling and cooling steps, it is necessary to have a good liquid thermometer that can measure from approximately sixty degrees Fahrenheit to two hundred and twelve Fahrenheit (the boiling point of water). Many kits come with specialized cleansers that serve to sterilize all of the homebrew equipment. However, a mixture of water and bleach can do the job just as well if your kit does not provide such a cleanser. Finally, any complete homebrew kit should contain 上一页 [1] [2] [3] [4] 下一页 |
