What is the common espresso shot count in all Tall drink variations?

For a Tall drink at Starbucks, which typically refers to a 12-ounce size, the standard number of espresso shots is indeed 1. This is consistent across various drink variations, whether it's a Latte, Cappuccino, or Americano. The Tall size is designed to deliver an optimal coffee experience with one shot of espresso, balancing the strength of the coffee with the volume of milk or water typically added to the drink.

This 1-shot standard is particularly important for maintaining consistency in flavor and strength across the menu. Larger drink sizes (like Grande or Venti) would have more shots to maintain the same coffee flavor profile, but for Tall drinks, one espresso shot is the well-established practice.
