How much ice is typically included in a medium iced latte from Black Rock Coffee Bar?

A medium iced latte from Black Rock Coffee Bar typically includes about 3/4 cup of ice. This measurement balances properly with the espresso and milk to achieve the desired flavor and temperature for the drink. The ice serves to chill the beverage while also diluting it just enough to prevent it from being overly strong as it sits. It ensures that customers enjoy a refreshing and balanced iced coffee rather than an overpowering espresso experience.

The other options, while they are all plausible amounts of ice, would either result in too much dilution (like 1.5 cups) or not enough chill (like 1/2 cup). Thus, 3/4 cup is the most appropriate amount to deliver the perfect iced latte experience.
