This is the Asahi Wilkinson Tansan Double Grape, an unsweetened, calorie-free carbonated beverage made with extracts from red grapes and Shine Muscat grapes grown in Nagano Prefecture.
The liquid was clear and colourless, with a subtle yet rich aroma of Shine Muscat grapes and vigorous carbonation. When consumed chilled, the flavour opened with the musky depth of red grapes at the head of each sip, followed by the brighter, tropical character of Shine Muscat emerging in the latter half. Although the drink contained no added sugar, the grape extracts provided a distinct aromatic presence that evoked the impression of sweetness without contributing actual sugars.
The overall flavour was reminiscent of Crush Double Grape, which also uses dual grape extracts. The carbonation in this case worked to sharpen the grape notes, enhancing the natural acidity of Shine Muscat and creating a dry, clean finish that refreshed the palate.
This beverage offered a rich and layered grape profile without sweetness or calories—refreshing, nuanced, and ideal for those seeking a flavoured soda alternative with clarity and restraint.
This Asahi Wilkinson Tansan Double Grape contained 500 mL. It was produced in Japan and purchased in Sydney, Australia in 2025.
