Fill a tall glass (highball or Collins) with ice all the way to the top.
A cold, full glass keeps the drink crisp.
Add 1/2 ounce each of vodka, white rum, gin, and tequila blanco.
Pour in 1/2 ounce triple sec for a touch of orange aroma and sweetness.
Add 3/4 ounce fresh lemon juice and 1/2 ounce simple syrup. This balances the spirits with bright acid and a hint of sweetness.
Give it a quick stir to chill and combine. No need to shake; the glass does the work here.
Top with a splash of cola (about 1–2 ounces) until the drink has that light iced-tea color.
Gently stir once more and garnish with a lemon wedge.
Serve with a straw if you like.
