The tartness of the hibiscus hits first, then it finishes soft and fruity — no sugar needed. Being caffeine-free, I've been drinking it after dinner without worrying about staying up. The 100g pouch has lasted me a good few weeks too.
Steeping a cup of this after dinner has become my little ritual — the hibiscus gives it that tart edge while the rosehip keeps it fruity rather than sharp. Caffeine-free, so I can drink it late and still sleep fine. The 100g pouch is a decent size too, lasted me about three weeks.
