Mmmmm nice. Lemongrass and Ginger flavoured sparkling water according to the label, and it’s like drinking a Chinese takeaway. That’s not as minging as it sounds because the drink is really refreshing and more-ish. At only 50 calories it also fits in to the diet category of drinks too. Sadly though, the wake-up factor is low, with no caffeine content listed on the label leading me to assume it must be very low. The caffeine actually in the product is naturally sourced from coffee beans but wasn’t enough to give me the required hit. Still, a very nice product and well worth a try.
