Yes, freshly ground pepper does taste fresher. This is because the flavor of the pepper seeds remains locked until the very moment when they are ground up by the electric pepper grinder. If the pepper was not freshly ground and had been previously ground and stored, then it has already lost much of its scent, its aroma, which gives the ground pepper its freshness. Pre ground pepper will still taste hot, but it will most probably not have the flavor or scent of freshly ground pepper from an electric pepper grinder and thus won't appear as fresh.
