Step-by-step explanation:
Typically, a chai latte at most coffee shops, including Starbucks, will vary in the number of pumps of chai depending on the size of the drink ordered. For instance, a Starbucks Grande size coffee, which is 16 ounces, would usually contain 3 to 4 pumps of chai concentrate to make the chai latte.
