What does the modification "ES" stand for in beverage preparation?

In beverage preparation, the "ES" modification typically stands for "Extra Strong." This term is commonly used to indicate that a drink, such as coffee, has been made with additional coffee grounds or a stronger brew method, resulting in a more robust flavor and higher caffeine content. It enhances the overall intensity of the beverage, meeting the preferences of customers who enjoy a bold taste.

While the other options do represent modifications that could be made to beverages—like "Extra Sweet," which would suggest additional sugar or sweeteners, "Extra Large," indicating a larger serving size, and "Extra Cold," suggesting a colder temperature—the specific "ES" abbreviation is most commonly recognized in beverage practice as signifying the strength of the drink rather than those other attributes.
