This is the Asahi Wilkinson W Peach,a zero-calorie carbonated beverage featuring extract from both white and yellow peaches grown in Fukushima Prefecture—formulated without sugar or artificial sweeteners.
The drink was clear and colourless, with a delicate peach aroma and assertive carbonation. Consumed chilled, the flavour opened with the floral, subtly sweet notes of white peach at the head of each sip, which transitioned seamlessly into the more tangy, vibrant acidity of yellow peach through the mid-palate. These layered peach notes delivered a juicy and nuanced fruit profile that lingered briefly before being swept clean by the strong carbonation. The effervescence approached a mild bitterness at its peak, contributing to a dry, crisp finish.
Despite the absence of sweetness, the peach character was vivid and rounded, offering a surprisingly rich flavour. The high carbonation level made it feel bracing and refreshing, especially in contrast to other calorie-free peach beverages such as Coca-Cola’s iLOHAS Peach, which, while also made with peach extract, is non-carbonated and marked by a savoury mineral undertone.
Overall, a dry, intensely carbonated peach soda with layered fruit expression and no sweetness—refreshing, flavourful, and superior in texture and finish to its still counterparts.
This Asahi Wilkinson Tansan W Peach contained 500 mL. It was produced in Japan and purchased in Sydney, Australia in 2025.
