This is the second of two chocolate bars from Mecsa Osha I've tried, the other being similar but at 75% cacao content. This chocolate bar, like the other, is produced from cacao beans from Peru, and is Fair Trade chocolate (meaning the local producers get paid more for their beans) and Organic. Mecsa Osha means "Sleeping Beauty" and refers to a mountain in the jungle of Peru where the beans are produced. The ingredient listing is fairly good, cocoa liquor, cane sugar, cocoa butter and soy lecithin.
How does it taste? Like the other one, the bar is very hard, you need a fair amount of strength, in your hands and teeth, perhaps because it is much thicker and less wide than other 100 g bars. This tasted better than the 75% bar, fruitier and less chalky. Ultimately, though, I wish to spare my teeth, and doubt that I would buy this bar again.
