Mises Economics Blog: Abolish the Alcohol and Tobacco Tax and Trade Bureau (TTB)
From the TTB website:
Distillation of Ethanol - In recent days, we have seen several news items on people distilling ethanol at home to supplement their gasoline needs. Unfortunately, some of the reports do not inform the public that it is illegal to distill alcohol without first obtaining a Federal permit through the Alcohol and Tobacco Tax and Trade Bureau (TTB). Failure to obtain a Federal permit prior to engaging in this activity is a criminal offence under the Internal Revenue Code.
