Lindt

Lindt are probably one of Green & Black's biggest competitors. They have a selection of chocolte bars called "Lindt Excellence" which actually even look quite similar to the Green & Blacks organic range of bars.

On top of that, they have 14 varieties of Lindt Excellence chocolate bars which is the exact same number as Green & Blacks had until the introduction of their most recent Caramel bar. Even the types of chocolate flavour are very similar across the brands. 

One major difference is that Lindt have gone for a 90% chocolate and even taken it to a 99% Cocoa chocolate which is the highest percentage I have found so far. Not only is it 99% but it is also actually encouraged for eating plain, not cooking into food as you might assume such a high percentage would be. In fact it actually comes with instructions on how to eat it properly on the packaging and some graphs showing how flavour and intensity change over time.
