The Possible Reason The Trenta Size Isn't Advertised At Starbucks
BY EIBHLIS GALE-COLEMAN
The trenta size at Starbucks is a colossal 30 fl oz cup for non-espresso drinks. However, it's not shown on the menu, probably for cost and practicality reasons.
By keeping this size quiet, Starbucks can offer it for select drinks and doesn't have to keep a trenta option for all drink choices, especially for costlier ones like a mocha.
Furthermore, since this serving size is extremely large, advertising it could lead to backlogs in queues, especially when it's doubtful there are standard recipes for this size.
