Green Tree is milder and sweeter than traditional absinthe, and cannot be touched with water in the same manner.
As such there is a different drinking tradition in the Czech Republic, known as the “fire ritual”.

In this ritual a slotted spoon is placed over a glass of absinth, with an absinth soaked sugar cube on top, which is then set ablaze. The fire is then doused with a small amount of water, producing a flavoursome, sweet and strong drink.
