This tiny sampler of the Japanese chocolate company Meiji comes in different cacao levels, and, to be honest, the only one I liked was the lowest percentage, 63%, as I think that cacao needs at least a little bit of sugar to be palatable. If there is little or no sugar, then the cacao needs to be really good and flavourful, if it is neither of these, then it is fairly inedible. The 99% was too chalky and just plain bitter. The 86% was still a little too chalky and still a little too bitter. The 72% was not bad, though again the cacao was not great cacao. The percentage of sugar in the 63% masked the low quality of cacao, so it became palatable. Fortunately, all the bars were quite small.
