Manufacturing
Missourians over the age of 21 may manufacture up to 100 gallons per person each year of any alcoholic beverage for personal use, without further limitation, without taxation, and without any license. It should be noted, though, that for production of distilled alcohol (i.e. not beer or wine) for personal use, it probably still is necessary for the private citizen to obtain a permit from the Federal Alcohol and Tobacco Tax and Trade Bureau and meet other requirements under federal law.
Besides that, however, the only alcohol which is illegal for sale or possession in Missouri is that which has been manufactured without a license and/or that on which the required taxes have not been paid.
