First you need a yeast. Most people use Saccharomyces cerevisiae. First you need to sterilize you source of carbon. Second S. cerevisiae produce ethanol anaerobically but a certain level of oxygen is required. You can produce alcohol in fermentation chamber which can be a large container with a small neck. You put a plug on it with a swan neck or a device that let the CO2 out and not contaminant goes in. You can always check your local bootlegger, it probably has all the necessary material for brewing.
