Los Amorosos
Shake all but sparkling wine, strain, serve up or on a rock, top with rosé.
The strawberry-infused tequila is called Tequila por mi amante, and is first cited in Charles H. Baker's Gentlemen's Companion. A recipe can be found here: bit.ly/dyEs1J Spanish speakers will note that "Tequila para mi amante" seems more likely to have been the original name than "por mi amante" ("for my lover," rather than "by my lover"), but it wouldn't be Baker if it weren't odd and confounding.
The original version of this drink called for half an ounce each of Lillet Rosé and rhubarb syrup instead of the St. Germain, a quarter ounce more lime, and no sparkling wine. I decided to update this drink to reflect what I think would be the more popular recipe and list the original here, rather than create two separate listings for very similar recipes.

- Havana Harbor Special — St. Lucian Rum, Sweet vermouth, Cherry Liqueur, Absinthe, Bitters, Club soda, Lemon juice, Simple syrup
- Colletti Royale — Reposado Tequila, Rosé Champagne, Triple sec, Elderflower liqueur, Orange bitters, Blood Orange Juice, Lime juice
- Brass Flower — Gin, Champagne, Elderflower liqueur, Grapefruit juice
- I Should Buy A Boat — Champagne, Barbados Rum, Grapefruit juice, Cinnamon syrup, Grapefruit
- The End of Something — Champagne, Absinthe, Elderflower liqueur, Grapefruit juice, Grapefruit peel
I've only ever made TPMA with (cheap) blanco; I don't know how the smokiness from a reposado would complement the strawberry favor. It would probably work well with the rhubarb, though. Interesting idea. I might give it a shot this year when strawberry season rolls around, I'm almost out of my current batch. Calle 23 would probably work.
So two quick things. Have you made this with both blanco (Baker) and reposado (Taggart) tequila? I'm going to change this to read Blanco tequila (strawberry infused) to simplify things.
