This one-ingredient (cocoa mass) bar had an intriguing, balanced green and savory aroma. The melt was even and smooth. with a relatively creamy, thick (almost nut butter-like) mouthfeel. The flavor included a slightly tart and astringent green (think not quite fully ripe banana with a hint of red currant), true chocolate and savory/salty notes, that mellowed into nice bold but quite smooth 100% cacao taste with a very slight astringency and a fleeting buckwheat pancake note in the finish. For a 100% cacao dark chocolate, this was quite smooth, offering balanced complexity without being too bitter.
Like any ultra-dark bar (with no sugar), I enjoyed re-tasting this bar. It continued to evolve over the course of the day, mostly with the same flavor and aroma notes mentioned above. Chocolate flavor will vary depending on time of day, temperature, proximity to a meal/food/beverage choice, a taster's body/mouth chemistry, and other mysterious factors.
