Terra Nostra organic Dark Chocolate 73% Intense Dark

Suggestions of raspberry. No sweetness, no bitterness (okay, an overtone of it). Stark. 7

Ghirardelli Intense Dark Twilight Delight 72% Cacao

Not much external flavor: basic chocolate. Slight bitterness. Some chalkiness. Unremarkable. 6

Askinosie Chocolate San Jose Del Tambo Ecuador 70% dark chocolate

Rich array of flavors on first taste. Deep chocolate, sweet orange, some berry. These flavors persist, leading to a pleasant finish. Zero bitterness. 9

Godiva Chocolatier Santa Domingo Dark Chocolate 85% cacao

Tangy. Citrus flavor burst. Very low amount of bitterness, not much aftertaste -- minor metallic residual taste. Thin bar. 7

Taza Chocolate Stone Ground Organic Chocolate 70% Dark

Chalky texture with a sharp bitterness. Strong vanilla note in the aftertaste. 5

Valrhona Le Noir Extra Amer 85% Cacao Dark Bitter Chocolate

Dark and bitter is right. Here's an 85% cocoa bar that is all-over "bitter". And "dark." Very little sweet chocolate flavor, maybe none. If you want a kick in your dark chocolate pants, this will do it. Lingering bitter aftertaste, on the harsh side. 6

Endangered Species Chocolate Supreme Dark Chocolate 72 percent cocoa content

Very bitter. Coffee taste. Aftertaste is rough. Like the back of a gorilla. 5

It's interesting to compare to the Endangered Species 88% cocoa that I tried earlier -- I like that one, but this one lost me with the strong bitter flavors, much more dominant than with the 88%. Surprising.
