BRIEF: “Our Sour Cherryade offers a tangy twist on a classic favourite. It's lightly sparkling for an extra refreshing taste.” SOOT’S TAKE: “How often do you come across cherryade around here—let alone sour cherryade? Practically never. Unless, of course, you happen to be at the right M&S at the right time, when it’s going for a dollar a can. Even better, it tastes like it has at least 30% less sugar than your typical cherry soda.”
