Japan's First Commercial Mall Debut! 'SPARK RICH' Pop-Up Store Offering 'EXTRA BURST' — Asahi Beverages' Highest Carbonation Pressure Ever — Opens at CIAL Yokohama and Maihama Ikspiari®.

EXRTA BURST

milkkiss Co., Ltd. is opening 'SPARK RICH,' a limited-time pop-up store where visitors can experience 'EXTRA BURST (Ekusutora Baasuto),' the high-carbonation server developed by Asahi Beverages Co., Ltd., at CIAL Yokohama and Maihama Ikspiari.

'EXTRA BURST' is a high-carbonation server that achieves the highest gas pressure in Asahi Beverages' history. Thanks to its patented horizontal dispensing nozzle technology, it delivers an overwhelming sensation and refreshing experience that previous carbonation servers could not achieve.

By using a unique technology that dispenses carbonated water from the nozzle toward the side of the container, minimizing pressure loss during pouring, it achieves the highest gas pressure carbonation in Asahi Beverages' history.

This marks the first time the system is being deployed in commercial facilities beyond offices and hotel lounges, allowing many customers to enjoy a refined carbonation experience.

Highlights of 'SPARK RICH'

① Japan's first debut in commercial facilities: Experience the intense carbonation created by 'EXTRA BURST'

While conventional servers dispense carbonated water vertically from the nozzle, EXTRA BURST dispenses it horizontally. The uniquely developed nozzle gently pours carbonated water onto the inner wall of the container, minimizing gas loss.

This allows visitors to experience high-pressure, chilled carbonation that is difficult to achieve with PET bottles, cans, or bottled carbonated drinks.

② Limited collaboration float with popular soft-serve brand 'milkkiss'

We will offer a new sensory float menu that blends the rich sweetness of milk with the stimulating carbonation of 'EXTRA BURST'.

・Maihama Ikspiari Exclusive: Soft Serve Float

③ Ultra-rich domestic fruit juice experience: 'Fruits Presso'

'Fruits Presso,' launched by Asahi Beverages, is an ultra-concentrated fruit juice drink made by carefully pressing selected domestic fruits. It includes upcycled flavoring extracted from fruit peels, cores, and seeds left over after juicing.

We deliver a new fruit carbonation experience that preserves the natural aroma and taste of fruit while optimizing compatibility with strong carbonation.

④ Sugar-free, new-sensation craft energy drink enjoyed with strong carbonation

At 'SPARK RICH,' we also offer an original craft energy drink specially designed to pair perfectly with strong carbonation.

No sugar is used; sweetness comes from honey. Passion fruit juice is added to bring out the fruit's natural vibrant aroma and refreshing acidity without relying on artificial flavors or coloring.

The bursting sensation of 'EXTRA BURST' combined with the tropical flavor of passion fruit creates a new energy drink that delivers both refreshment and satisfying taste.

The high-carbonation server 'EXTRA BURST,' which achieves the highest gas pressure in Asahi Beverages' history, has primarily been deployed in offices and hotel lounges. We are thrilled to now offer this experience to more customers through a limited-time store in commercial facilities.

The greatest appeal of 'EXTRA BURST' is the overwhelming sensation and refreshment only possible with freshly made carbonation. We hope visitors will enjoy this unprecedented high-quality strong carbonation experience at 'SPARK RICH'.

Moving forward, we will continue to propose new values and ways to enjoy carbonation, delivering excitement and smiles to our customers.
