We may have found the “kiki” and “bouba” of Diet Coke.

I might still be), but the Diet Coke girlies definitely got to me.

Before I knew it, cracking open a 2 p.m.

Bottles and cans of Diet Coke lined up on a counter

Diet Coke in the office became somewhat of a ritual that I always looked forward to.

Each Diet Coke was assigned a number and then poured into 3-ounce cups, which we labeled.

Before we dive into the results, we need to have a chat about McDonald’s.

Not going to lie, this kind of blew my mind.

With all that Diet Coke science in mind, we came up with a McDonald’s plan.

Second, dilute the Diet Coke with about 1 ounce of water to replicate the dilution from melted ice.

Last, pour it into SodaStream bottles to prevent it from going flat.

I also realized I definitely needed more.

Again, they were flat.

Whew, what an emotional roller coaster.

With our McDonald’s fiasco finally settled, here is our official Diet Coke ranking from worst to best.

If anything, we all thought it would have some of the best fizziness.

Alas, we were left disappointed.

OVERALL RATING: 1.5/5

Glass Bottle

A few of our testers thought it had that “classic” Diet Coke taste.

Some thought the flavor was flat, and when it came to fizziness, they were split.

Some found it to have a good fizz, while others thought it was flatter or even watered down.

But I definitely understand that it didn’t meet everyone’s bubbly Diet Coke expectations.

Funnily enough, half of our testers thought this was the plastic bottle.

One person described the flavor as “smooth and light,” and I’d have to agree.

Whereas McDonald’s was “bouba,” the canned Diet Coke was aptly described as “kiki.”

I took one sip and immediately said, “Whoa, zigzaggy.”

Even though guesses were still relatively split, most people guessed this was the can.

One tester literally took one sip and said, “Yup, that’s a can” it wasveryimpressive.
