American-made Tequila-like Spirits, Revisited
I don't know "for sure" what would happen if someone decided to start making Tequila here in the United States, . . .
I started a thread about just such a situation early last year in regard to a product initially called "Temequila", but now called "JB Wagoner's".
Although the purveyor can't call his product "tequila", he certainly uses the word at every opportunity on his website -- by way of explaining why he can't use the word on the label.
