Absinth is produced mainly in the Czech republic where it gets its Bohemian moniker. It doesn't contain anise, fennel or other herbs normally found in absinthe and can be extremely bitter. Often the only similarity is the use of wormwood and a high alcohol content, and it should be considered a different product. Since there are currently few legal definitions for absinthe, producers have taken advantage of its romantic associations and psychoactive reputation to market their products under a similar name. Many Bohemian style producers heavily market thujone content, exploiting the myths that surround thujone even though none of them contain enough thujone to cause a noticeable effect.
