At the 80% cocoa level we start to see a greater variety of textures and flavours. The Marou Tiền Giang 80%, for example, has a much bitter flavour than the Zotter Criollo. This is the main due to the type of bean used, with Criollo being a finer flavour and more mellow bean than Trinitario, but also because the relative inclusion of cocoa solids compared to cocoa butter is also different. If you did want to find a more intense 80% chocolate bar then it is worth looking at individual product descriptions or looking at some 82% dark chocolate such as the Upala, or even 85% chocolate and up to 90%.
