A super flavourful retro treat, use at around 10%, it naturally splits so a shake before each use is a must, it certainly packs a punch, I only wish I knew just what they add to achieve it, maybe alcohol or Absinthe, the only downside is it is a bit overpriced, £10 for a 30ml bottle , I have found other blackjack concentrates that are 1 to 1 for flavour compared with the sweets but lack the punch you can get with this one, if anyone discovers what makes that punch please post.
