Which modification would you use to indicate a beverage is less strong than usual?

The correct modification to indicate a beverage is less strong than usual is referred to as "HD," which stands for "Half Dose." This terminology directly communicates that the beverage has been made with a reduced amount of the primary ingredient, typically coffee or espresso, resulting in a milder flavor profile. Using "HD" effectively informs both the barista and the customer that the drink will be lighter in taste compared to the standard preparation.

In contrast, other options serve different purposes: "ES+" indicates an extra shot of espresso, thereby increasing the strength, while "HCP" and "HS" refer to other specific modifications or enhancements that don’t convey the idea of reduced strength. Therefore, "HD" is the appropriate choice for signaling a beverage that is intentionally made less strong.
