As everyone knows, on May 24, 2021, Luckin Coffee launched three brand new "First Love Green Grape" series products:

When our workshop team learned that Luckin Coffee's new products were themed around "first love flavor," we couldn't help but smile knowingly :)

So we couldn't resist ranking these "first loves"...

Seeing this scene, our workshop team immediately decided to find an auspicious day to test the taste of this "first love" (laughs...)

Luckin Coffee First Love Green Grape Sparkling Americano

Recommendation: 3.5 stars

According to the official introduction, this is a new member of the "classic sparkling Americano flavor" series~

It's a new product made with IIAC Gold Award coffee beans + Ristretto (a type of extraction method in espresso) finely extracted concentrated coffee + refreshing soda water~

Ristretto coffee extraction method

Perhaps seeing this, you might ask what is Ristretto? (Confused face???)

Let me give you an analogy:

If Espresso is the essence of coffee, then Ristretto is the essence of Espresso (laughs)

Alright~ enough chatter, let's continue~

When I took this green grape sparkling Americano from the barista, the distinct layers of coffee and sparkling water were visually appealing, making me eager to take a big sip.

How should I describe it? The first impression is the characteristic burnt aroma of dark-roasted coffee beans that suddenly rushes into your nasal cavity, followed by the tongue—you can clearly feel your tongue enveloped by the sparkling water, and at the moment of swallowing, the sweetness of the green grape sauce blends with the bitterness of the espresso.

Green grape sparkling Americano tasting

This "first love" has an overall flavor that's refreshing, sweet but not cloying, burnt but not bitter. It's somewhat similar to drinking white grape sparkling wine, but like a first love that ends prematurely, the aftertaste of this entire drink is... very short...

Luckin Coffee First Love Green Grape Oat Milk Latte

Recommendation: 3 stars

According to the official introduction, this cute drink is made with espresso extracted from IIAC Gold Award coffee beans + lactose-free oat milk + Shine Muscat green grape flavored syrup~

Oat milk latte ingredients

First, the iced "oat milk first love" carries the aroma of oat grains. Since we did our homework beforehand and learned that the entire "first love" line cannot be made sugar-free, we all obediently ordered half sugar.

Mmm~ the half-sugar sweetness was just right. It has a medium to high intensity of grape fermented wine aroma, almost like the taste of fully ripe grape flesh, with caramel and brown sugar notes. The overall mouthfeel is rich and full-bodied, and the oat milk gives a heavy sensation on the tongue. I like it~

Just as the poster says: "Oat milk and sweet-tart refreshing green grapes intertwine together, creating an exceptionally fresh mouthfeel~ as if it's the heart-pounding feeling when you fell in love that early summer~"

Second, the hot "oat milk first love" has a unique seaside atmosphere, like walking on the shore with a gentle breeze blowing across your cheeks, giving that salty feeling.

As that endlessly summarized saying goes: those who like it will really like it~

Research shows that our sense of smell can continuously store images—connecting scents with memories

(Wry smile) The hot "first love" is remarkably like those inexplicable preludes before the first love game ends (another wry smile)

Luckin Coffee First Love Green Grape Thick Milk Latte

Recommendation: 3 stars

Thick milk latte ingredients

According to the official introduction,

This "first love" is made with espresso extracted from IIAC Gold Award coffee beans + cold brew thick milk + pure milk + Shine Muscat green grape flavored syrup

To be honest, with the "oat milk first love" as a comparison, this "thick milk first love" appears somewhat... unremarkable (laughs)

What happened to the promised just-right sweetness? What happened to the promised subtle acidity?

Dear readers~ please forgive my dull sense of taste~ I'm afraid I'll disappoint you all (expression)
