I tried every Slurpee flavor at 7-Eleven I could find and ranked them all from worst to best

• I tried the eight Slurpee flavors I could find and ranked them from worst to best.
• The Vitamin Water squeezed-lemonade and Coca-Cola Slurpees weren't as good as the others.

To celebrate National Free Slurpee Day on July 11, excited customers flock to 7-Eleven in the hopes of snagging a free frozen treat — though, those rules might change this year.

So to prepare for the occasion, I tried eight Slurpee flavors and ranked them from worst to best.

Vitamin Water squeezed-lemonade Slurpee

This flavor has zero sugar and 50% fewer calories, so I didn't have high hopes.

This option wasn't bad, but it simply went against everything the sweet staple stands for. No one drinks a Slurpee because they're cutting down on sugar.

The fake sugar had a noticeable aftertaste, and the mellowed-out lemon flavor didn't have enough zest to it.

It tasted like a frozen version of lemon-flavored Vitamin Water.

Coca-Cola Slurpee

If you are someone who likes soda, and particularly Coca-Cola, you'll likely love this flavor.

Lightly carbonated, sweet, and refreshing, this Slurpee was truly the frozen version of its namesake soda.

That said, it doesn't beat an ice-cold, freshly opened bottle of classic Coke. Lacking that iconic effervescence and carbonation, this Slurpee didn't have the same satisfying quality.

It just tasted like a frozen, flat Coke — so I placed it low on this list.

Piña-colada Slurpee

As a Piña-colada lover, I absolutely adored this Slurpee. That said, my boyfriend, who doesn't like the namesake cocktail, hated it.

It was everything I'd usually want in a piña colada, but in artificial, Slurpee form.

The ratio of coconut to pineapple was solid. Although it could've used a richer flavor and texture, this option wasn't overly sugary, sweet, or fruity and was still quite creamy.

I would love to drink this on a beach somewhere tropical, maybe even with some rum in it.

Cherry Slurpee

Cherry is a classic Slurpee flavor that's reliable and always delicious.

But compared to some of the others, this flavor was so sweet and tasted quite artificial, like a snow cone.

It was more like a maraschino cherry than a real one, so keep that in mind when choosing the flavor.

Peach Perfect Slurpee

When I initially saw this peach flavor, I thought it would taste overly sugary, like artificially flavored candy, but I actually found it balanced and refreshing.

Some Slurpee connoisseurs may say this flavor tastes too natural, but I loved it.

It was sweet enough without being overly sugary, like a well-balanced, natural peach soda

Blue-raspberry Slurpee

I've always been team blue raspberry since the option encapsulates all of my favorite berry flavors — particularly raspberry — and combines them with a zesty, citrusy touch.

It was super sweet, yet perfectly balanced by the tangy notes, slight carbonation, and refreshing aftertaste.

Its bright-blue color also sets it apart from red fruit flavors, like cherry or strawberry.

Mountain Dew Major Melon Slurpee

This watermelon flavor was divine and radiated summertime vibes.

It tasted artificial, but not in an overwhelming way, and its balanced melon flavor practically begged to be guzzled down.

The sweet flavor paired well with the light carbonation. Plus this drink wasn't syrupy or sugary enough to make me feel gross, also reminding me of a refreshing, natural soda.

WINNER: New and exclusive cherry Slurpee

I was excited to try this "new and exclusive" cherry flavor to see if it actually tasted like real sugar and juice, and I'm happy to report it was a lot better than the traditional option.

It wasn't overwhelmingly sugary or syrupy but still boasted that classic cherry flavor.

This Slurpee's balanced tartness and refreshing fizzy texture also made it wonderfully thirst-quenching.
