Query: Dark Chocolate. It's good, but it's not for everyone.

This is a bag of dark chocolate squares.The dark chocolate squares are individually wrapped.Good quality.There are three different types of dark chocolate in this bag.The 60% percent dark chocolate, which is the sweetest, but least dark.the 72% percent dark chocolate, which is less sweet, and more dark,and the 86% percent dark chocolate, which is not sweet at all, it is very bitter.It has a strong aftertaste to it. like chewing black coffee grounds. No milk, no sugar. Just black chocolate taste.I like dark chocolate. I find most milk chocolate to be way too much sugar, and way too sweet, and not enough chocolate.But the 86 percent dark chocolate is really dark and bitter.So if you really like bitter dark chocolate, go for it.
