What are the shots for an ICED unflavored drink in small, medium, and large sizes?

For an iced unflavored drink, the correct number of shots corresponds to the second option, which outlines the proper espresso measurements for small, medium, and large sizes. In this case, a small iced drink receives two shots of espresso, a medium also gets two shots, and a large is served with three shots.

This shot composition ensures that all sizes maintain a consistent flavor balance and strength, especially when served cold. The espresso's intensity needs to be slightly adjusted for the larger drink size to enhance the overall taste without diluting the beverage.

The other options either misalign with the standard formulation for iced drinks or do not provide the incremental increase in espresso shots that is generally expected for the large size, which would require more shots to accommodate the larger volume of the drink. This method maintains the drink's quality and flavor profile across different sizing.
