What does 1/2 caf mean?

The term "1/2 caf" refers to a blend of coffee that contains equal parts of regular and decaffeinated coffee. This means that the drink will have both the caffeine content from the regular coffee and the lack of caffeine from the decaf in a balanced ratio, resulting in a milder caffeine effect. This is particularly appealing to customers who want to enjoy the flavor of coffee without the full impact of caffeine, making it a popular choice for those looking to reduce their caffeine intake while still enjoying a coffee beverage.

The other choices do not accurately represent the concept of "1/2 caf." While "regular coffee only" does not incorporate any decaf, two pulls of decaf would imply an entirely decaffeinated drink, which is contrary to the definition. Lastly, half the size of a regular shot does not relate to the caffeine content and does not describe the compositional balance between regular and decaf coffee. Therefore, the answer effectively highlights the unique blend characteristic of "1/2 caf."
