This is the Blueberry Yuzu Sparkling ($7.70; less ice, fixed sugar) from Tea Shop Express, featuring sparkling butterfly pea tea flavoured with blueberry syrup, yuzu marmalade and perilla.

The beverage presented with a translucent purple hue, with slivers of yuzu rind suspended throughout and settling at the base of the cup. Aroma opened with sweet blueberry, supported by floral citrus from the yuzu marmalade. The drink needed to be consumed soon after purchase, as the cup seal was insufficient to contain the carbonation pressure and gradually leaked.

Initial contact delivered distinct sweet blueberry notes with a refreshing berry character, carried by the mild, earthy, slightly grassy lightly carbonated butterfly peabase. The carbonation provided immediate lift without masking the fruit profile.

Through the mid-palate, the floral citrus qualities of the yuzu marmalade developed, broadening the berry sweetness rather than competing with it. Towards the finish, gentle herbal anise notes from the perilla emerged, lifting the blueberry profile so that it avoided becoming cloying while adding further dimension to the yuzu. The carbonation persisted throughout, cleansing the palate and leaving a light, refreshing finish.

The slivers of yuzu rind regularly clogged the standard straw supplied with the beverage, often preventing the drink from flowing. A wider boba straw would have been more appropriate, allowing the marmalade to contribute both texture and more pronounced bursts of yuzu flavour rather than becoming an inconvenience.

Overall, a sparkling fruit beverage with a layered flavour trajectory and well-integrated carbonation, resulting in a refreshing and structurally balanced drink, despite the practical shortcomings of the packaging and straw selection.

This Blueberry Yuzu Sparkling was purchased from Tea Shop Express in Sydney, Australia in July 2026.
