Found in Tesco, £1.05 a tin. It tastes genuinely wonderful and I’ll be buying more though at that price it’s 4x the price of my usual caffeine loaded tipple. And not only does it taste fantastic (by far the best “energy” drink – and I’ve drank them all) it has a super juicy 46.5mg caffeine/100ml. That’s 50% higher than my usual caffeine loaded tipple. Love it.
