Nayuki's Little Green Bottle: The "Slim" Refers to the Bottle, Not Your Body — Fruit and Vegetable Drink Slimming Claims Spark Controversy Again

A hit drink from Nayuki, the "Nayuki Slim Little Green Bottle," sparked discussion due to a line of small print in its product details. In the official explanation, "slim, light" refers to the new square bottle shape being slimmer and more portable, not to the drink having any functional benefits. Many consumers had assumed it was a fruit-and-vegetable tea suitable for people trying to lose weight, and were taken aback after learning the truth. This kind of situation is not an isolated case—fruit-and-vegetable drinks from brands such as Good-meh and Luckin also often use "body-slimming" and "light-body" as selling points, then add clarifying small print. How many calories are actually in a cup of kale drink? The gap between merchants' marketing and consumers' understanding deserves the attention of every coffee and tea lover. [more…]

Nayuki's Little Green Bottle criticized as tasting like vegetable-leaf bathwater; the company responds: it's truly freshly squeezed, and the color change is due to oxidation.

The first product in Naixue's newly launched "Daily 500 Fruit & Veggie Bottle" series, "Slim Little Green Bottle," focuses on the daily 500g fruit and vegetable ratio recommended by the Chinese Nutrition Society, and claims to have no added sugar and to be freshly squeezed to order. After hitting the market, however, quite a few consumers reported that it tasted noticeably sweet, with some even describing it as "syrup-like," and others posted photos showing the drink looking yellowish, questioning whether it was really freshly squeezed. Naixue employees responded on social media that the sweetness comes from fruits such as apples, pears, and sweet oranges that naturally contain sugar, while the yellow-green color is a normal phenomenon after apples oxidize, and stressed that all ingredients are processed the same day and kept refrigerated for a limited time. The controversy also sparked playful online discussion about the kale leaves at the bottom of the cup. [more…]

Blue Bottle Coffee's limited-edition green cup quality control fails: Controversy over hand-glazing and differences in cup-bottom markings in China spark heated discussion

Blue Bottle Coffee recently launched a 2023 holiday limited-edition pine green mug in Japan, which quickly became a hit in collector circles thanks to its high aesthetic appeal. After the China region officially announced its release on November 5, the mini-program sold out instantly, with many enthusiasts going so far as to use international proxy shopping services or visit physical stores just to get one. However, when the mugs arrived after crossing the ocean, many consumers discovered flaws such as uneven glaze and bumpy walls, and customer service's response citing "artisan handmade" further sparked skepticism. In addition, the China version only has "Made in Japan" printed on the bottom, creating a gap compared with the complete information on the Japanese version. Even more frustrating, some online orders arrived with the mug shattered upon opening due to flimsy packaging. Front Street Coffee has also been following this incident, and this article will provide a complete rundown of the Blue Bottle green mug's journey from hot demand to backlash, offering a reference for coffee gear enthusiasts.

Heytea's Super Plant Tea launches another new product, the Beetroot Beauty Bottle, with polarized reviews

After the National Day holiday, Heytea launched the third product in its Super Plant Tea series—the Beetroot Beauty Bottle. This fruit-and-vegetable tea drink, starring beetroot, continues the previous slimming bottle line and claims to have beauty-enhancing and slimming benefits. Beetroot, an ancient ingredient originating from the Mediterranean, is rich in betalains and dietary fiber and holds a high status in European folk tradition. The new product is made from 100% freshly squeezed beetroot, combined with apple juice, pineapple juice, lemon juice, and a fragrance-free Green Yan tea base, offering a fresh and light taste. However, consumer feedback has been polarized: those who like it appreciate the balance between the slight astringency of the whole food and the tartness of the apple, while those who don't describe it as tasting like a mouthful of dirt. Heytea's previously launched Champion Slimming Bottle and Fire-Clearing Slimming Bottle both achieved impressive sales, and competition in the fruit-and-vegetable tea segment is intensifying.

Heytea's Refreshing Slimming Bottle has gained popularity for its fresh green color and freshly squeezed fruit-and-vegetable concept, but recently some consumers have reported receiving drinks that are orange-yellow or green with a yellowish tinge, questioning whether the product matches its marketing. Store employees explained that the color change may stem from yellowing kale leaves or oxidation of apple juice, and that it is not spoilage—the drink is still safe to consume. However, some consumers remain concerned about quality control. This article reviews the sequence of events, employees' statements, and consumer feedback, and also mentions Front Street Coffee's reference views on quality control. [more…]

Blue Bottle Coffee's holiday limited-edition mug sparks color discrepancy controversy, gap between actual product and promotional images triggers wave of returns

At the end of each year, Blue Bottle Coffee releases holiday-limited merchandise in Japan. This year's theme is "Delicious Gifts," featuring items such as the caramel-colored Kiyosumi Shirakawa cup and the dark caramel Kinto ceramic mug. However, after the products went on sale, many consumers found a noticeable color difference between the actual items and the official promotional images—the rich caramel color shown in the ads turned into a pale milk-tea shade once in hand. In addition, quality-control issues such as crooked logos, flaws on the cup body, and uneven coloring appeared frequently, triggering a flood of complaints and returns. The official explanation attributed the color discrepancy to the hand-glazing process and the influence of lighting during photography, but the controversy continues to intensify. [more…]

Heytea Dark Slimming Bottle Halloween Limited Edition Launches: Freshly Squeezed with Cilantro, Celery, and Kale—Employees Can't Stand the Smell

On the eve of Halloween, Heytea launched a limited-edition special drink, the "Dark Slimming Bottle," as a new member of its Super Plant Tea series. This beverage uses freshly squeezed kale and celery as its base, blends in a variety of fruit and vegetable juices, and adds a generous amount of fresh cilantro segments, emphasizing a dark visual style. Cilantro lovers reported that the cilantro flavor was not prominent after drinking it, because the whole cilantro segments were not chopped and juiced, serving only as decoration, and it was jokingly called "cilantro bathwater." However, this new product made store employees complain endlessly — the cumbersome process of washing cilantro and trimming celery, plus the strong smell, led many workers to say outright that they "feel like throwing up just from smelling it," with complaints mounting on social platforms.

Following its light-body fruit and vegetable bottles and vitamin A fruit and vegetable bottles, Gu Ming has once again incorporated espresso into freshly squeezed fruit and vegetable juice, launching the new Light-Body Fruit and Vegetable Americano, in an attempt to attract more consumer groups with a combination of health and coffee.

This article compiles the formula information, visual changes, and genuine netizen reviews of this fruit and vegetable Americano for coffee lovers' reference. [more…]

Nestlé and Master Kong enter the fray one after another—can label-free bottled beverages become a new trend in low-carbon packaging?

In recent years, as environmental awareness has risen, label-free bottled beverages have moved from once being considered "alternative" to becoming legalized. Brands such as Nestlé Japan Coffee, Asahi, Suntory, and Evian have successively tested the waters, and domestically, Master Kong has also launched label-free iced tea. Such products are mostly sold by the case, with only the shelf life and product name laser-printed on the bottle, while legal information is printed on the outer box.
