I like most Pralus bars, but this one did not get there for me. The "best by" date for this bar is August 2013, so it is well within that. However, the bar seemed to have some surface issues. The photo below shows the surface of the bar before I tasted it. The left arrow above the Pralus logo shows an area that should be smooth, but is instead rough and uneven. The right arrow shows an area on the right side of the bar that looks like it has been marred and roughened before packaging in the foil that covered it. I doubt that the bar's taste is related to this unexpected condition of the bar, but it could be, so take that into account.
