I tried iced black coffee from 4 coffee chains, and there's only one I'd like to buy again

Although I did not find the drink to be as "full of flavor" as the chain's website mentions, this coffee had a crisp, light flavor that was enjoyable without being overwhelming.

This was definitely the most refreshing iced coffee I tried, and I would absolutely order this again.

Interestingly, this was also the cup of coffee that had the largest amount of ice in it. Usually, a lot of ice can lead to a super watery, overly diluted drink, but I was pleasantly surprised that wasn't the case here.

The iced coffee from Tim Hortons was the only one that seemed to have a clear flavor. The brew actually tasted slightly nutty, which was pleasant.

However, despite being described as a medium roast, the brew seemed very strong and quite bitter.

The coffee didn't have a lot of ice, either. I think if more ice had been used and melted into this coffee, it may have been diluted enough to be more drinkable.

In my experience, Starbucks makes its iced coffee using its medium-roast Iced Coffee Blend, which is described as "smooth" and "caramelly." This was not my experience.

I found this coffee to be the most bitter of all the ones I tried, and difficult to finish. Just like the hot Starbucks coffee I'd previously tasted, this is not a drink I would order again.

This also had the least amount of ice, which should've been a good thing — more room for coffee! – but didn't do much to sway my opinion on the overall drink.

When I tried hot black coffees from these same four chains, Gloria Jean's brew was my favorite — so I was surprised that the chain's iced coffee was too harsh for my liking.

The coffee tasted rich, but it was very bitter and ultimately difficult to drink. This drink had a lot of ice — just slightly less than what Dunkin's had — but it didn't do much to dilute the overly bitter flavors of the coffee.

Dunkin's iced coffee was the most enjoyable and drinkable coffee I tried by far, and it was smooth and crisp in a way that the others just weren't.

Overall, every coffee was affordable and I got all of my orders quickly — but if I were to order an iced coffee from any of these chains besides Dunkin', I'd probably feel the need to add some cream or sugar.
