Whether you call it large, venti, grande, or grand, the 20 oz. cup is the new standard in beverage service. Hot or cold 20 oz. cups can be used to serve water or fountain drinks, or coffee and tea. The 20 oz. in cups size increases the perceived value of the beverage purchase and is large enough that customers are more likely to be full and not get refills. Since there are 2.5 cups in 20 oz. and 2 cups in a 16 oz. cup you only lose an additional half cup of product when you serve a customer the larger, more appealing 20 oz. cup.
