Asahi Future Lemon Sour is a canned chu-hai beverage designed to replicate the experience of enjoying a lemon sour at an izakaya. The Plain version features a drier and more bitter flavour profile, tailored for those who prefer less sweetness in their drinks. A unique aspect of this product is the inclusion of a fresh lemon slice inside the can, which floats to the surface when opened, adding an authentic and refreshing touch. Availability may vary due to its popularity and limited production.
