What is the name of Starbucks' iced coffee steeped for 20 hours?

The Starbucks iced coffee steeped for 20 hours is Cold Brew. Unlike ordinary iced coffee, which is brewed hot and then chilled over ice, cold brew is made by slowly steeping ground coffee in cool water without heat.

Starbucks describes its Cold Brew as a small-batch drink made from a custom blend of beans chosen for long, cold extraction. The process produces a smooth, naturally sweet flavor with less of the bright acidity often associated with hot-brewed coffee. The finished drink is served over ice and can be customized with milk, syrups, or cold foam.

A common mix-up is Nitro Cold Brew. Nitro is not a separate brewing method: it begins with Starbucks Cold Brew and is infused with nitrogen as it pours, creating a cascading appearance and creamy texture. Iced Coffee is different again because it is brewed hot, often at double strength, and poured over ice. The 20-hour steep therefore points specifically to Cold Brew.
