Fine,

Tequila, Vermouth, olive juice is called a Trex

You’d have a Scotch Manhattan.

If you make a margarita with scotch, you’d have a scotch margarita.

We’re not mixologists designing new drinks.

I’ve made tequila with clamato juice, did I make a Tequila Cesar, or is it a different drink??

Gin Martini

Vodka Martini

Martinis is plural. You can make Martinis with any clear spirit. Whether or not you make it again is a different story.

I do like a gin martini, but as a tequila drinker, nothing beats a dirty Tequila Martini.

That makes sense
