Blue Chameleon

Although there’s nothing new about colour-changing cocktails, and indeed they’re doing the rounds on more than a few cocktail menus, we still thought it important to cover them in an article. This is something we first looked into back in 2014 as dry ice can create a very slight acidity (Carbonic Acid – don’t worry it’s completely safe) in a drink over time and we thought a gradual colour change would look really cool. We experimented with what we had to hand (red cabbage mostly) but the real break-through came when we heard of this Butterfly Pea Tea extract, or Blue Chameleon, from Thailand.

This extract, which is blue in colour, is also a natural pH indicator. A pH indicator is a substance that undergoes a physical or visual change when it’s exposed to either an Acid or Alkali. For our use with cocktails, as long as it’s used alongside a colourless cocktail or neutral colour, it will change from a blue to a pink-purple colour in the presence of acid. We get our Acid in the form of Citric Acid or Lemon/Lime Juice. Although there will be a slight change over time with JetChill’s Dry Ice, we discovered that it’s much more fun to let the customer create the reaction with a pipette of citrus juice themselves. The other advantage is that the Blue Chameleon is pretty much odourless and colourless and so can be used with a variety of spirits and mixers without impacting the flavours.
