Tested a caffeine chocolate, that was used my various parts of the German army in WW2 to keep awake & for a moral boost. Each capsule holds 16 pieces, 8 pieces being that equivalent of a cup of coffee, 16 is more than an energy drink.

You can clearly taste the coffee in there, though its not bitter. The milk chocolate tastes like an iced latte mixed with quality milk chocolate being very creamy. The dark chocolate is richer in flavor and more bitter, very earthy as well. It tastes akin to dark chocolate & black coffee, it would go great cold conditions.

The price was 4 Euro, for a 100 gram tin can. Too high a price for me to use in daily life, though when going hiking or just on a trip I'll be taking one or two of these.
