It is illegal to own a still, regardless of its intended use in the state of Utah. Residents can distill water, essential oils, etc. if they apply for a license and register the still, which I believe is the same general process for distilling alcohol.
Any person who—
- (1) Unregistered stills - has in his possession or custody, or under his control, any still or distilling apparatus set up which is not registered, as required by section 5179 (a); or
- (2) Failure to file application - engages in the business of a distiller or processor without having filed application for and received notice of registration, as required by section 5171 (c);
- shall be fined not more than $10,000, or imprisoned not more than 5 years, or both, for each such offense.
I was unable to find any information on fuel alcohol for this state.
Utah does offer distillery licenses but the state is the most constrictive against distillers I have seen and much more complicated (which is why I only found 4 distilleries in the state). The fees for a distillery are $3,800, with a $300 application fee and require a $10,000 bond.
There are several licenses you need to request to legally manufacture spirits. Below are the federal licenses only. Additional state requirements will need to be followed as well.
You must submit a request for a license to manufacture spirits: TTB 5110.41 Basic permit.
This license only allows you to produce spirits. You also need a license for the distilling equipment / distillery: TTB 5100.24 Distilled spirit plant
For manufacturing ethanol fuel you will need to submit a request for a TTB 5110.74 for a federal license.
