Iced Coffee is briefly hot brewed and poured over ice and served as a chilled beverage. Cold Brew is brewed for about 18 hours at room temperature for a very full flavor. Because of this process, Cold Brew has less acidity than Iced Coffee and makes for a super-smooth, clean cup of coffee that tastes very different than coffee over ice. And our Frappe uses a shot of espresso and is blended with ice and other artisan syrups.
