When it comes to iced coffee, people tend to have lots of feelings. Good, refreshing, summertime feelings, and bad, am-I-getting-ripped-off feelings. Because when you buy a cup of iced coffee, it’s hard not to wonder how much of the cup’s content is coffee, and how much is just a lot of ice.
The team at BuzzFeed put iced coffee from three popular brands (Starbucks, Dunkin’ Donuts, and McDonald’s) to the test. The video begins with three large cups of iced coffee—the coffee from McDonald’s is 22 ounces while the Dunkin’ Donuts and Starbucks coffees are both 24 ounces. The contents of each cup are then strained through the lids and poured into separate mason jars to separate the coffee from the ice.
How did it go? Well the McDonald’s and Starbucks coffees both totaled around 16 ounces without the ice. For Starbucks this means that 67 percent of the cup’s contents was coffee while this McDonald’s cup was filled with 73 percent coffee. Dunkin’ Donuts, however, ends up being a big winner in terms of their coffee to ice ratio—their cup was 92 percent coffee. However, the video notes that the numbers may not be entirely accurate as melted ice was not accounted for in the percentages.
This doesn’t necessarily mean that your iced coffee is extra diluted. As we’ve previously reported, some coffee shops use cold-brewed coffee for their iced orders and this brew tends to be more concentrated and flavor-packed (which also partially accounts for the increased cost). Of course you have to see if your favorite coffee shop uses this method. Ultimately the results of this iced coffee experiment can be filed away as one of those good-to-know type facts.
