Juper Co., Ltd. Launches 'ASAICHI CARE Grapefruit,' Reducing Bitterness and Expanding Product Choices

Sold separately from the herbal tea-flavored original; available on Naver, Coupang, and Market Kurly

SEOUL, South Korea, Nov. 13, 2026 /PRNewswire/ — Juper Co., Ltd. has added a grapefruit-flavored product to its hangover relief brand ASAICHI CARE. The new product was developed in response to consumer feedback that the existing herbal tea-flavored product was too bitter. While continuing to sell the original, Juper is offering the grapefruit flavor as a separate product so that consumers can choose according to their taste.

The new product’s official name is "ASAICHI CARE Grapefruit." According to Juper, it launched on June 18 and is sold on Naver, Coupang, and Market Kurly. Rather than changing the flavor of the existing product across the board, the core of this product line expansion is to offer the herbal tea and grapefruit flavors side by side.

The development was prompted by the reactions of consumers who had tried the existing product. Juper said it had received feedback on multiple occasions that the original was too bitter. The company decided to keep the existing product for consumers who prefer the herbal tea flavor, while offering a different, easier-to-drink flavor to those put off by the bitterness. ASAICHI CARE Grapefruit is the product developed to reflect this feedback.

The packaging also differs by flavor. The original retains its existing green color, while the grapefruit product uses hot pink. By labeling "Grapefruit" in the product name and using a different packaging color, the company made it easy for consumers to tell the two products apart on online sales pages. The key changes the company disclosed with this launch are the flavor and the packaging.

ASAICHI CARE is a brand developed using "ACP-20," which Juper presents as a patented ingredient, along with its manufacturing process. The company plans to continue its ingredient research while also reflecting the taste and ease of consumption experienced by consumers in its planning of follow-up products. The grapefruit launch is an example of turning an inconvenience identified while selling the existing product into the development of a separate product.

Juper also intends to broaden its domestic sales touchpoints. In June, at "2026 Seoul Food" held at KINTEX in Goyang, Gyeonggi Province, the company introduced its products to domestic distribution professionals and discussed expanding its pharmacy distribution channels. The grapefruit product is currently sold online; new pharmacy listings and the start date for offline sales have not been disclosed.

Going forward, Juper plans to monitor domestic and international consumer response and expand the ASAICHI CARE product line. Just as it reflected feedback on taste from the existing product in the new one, the company intends to look at which flavors and methods of consumption consumers prefer when developing follow-up products.
