We at hoppsy (being Aussies) like a small head on our beer, but whenever we visit Japan we notice that the locals there love the head to take up a third of the glass. This must explain the need for this amazing product from Japan that helps you ruin improve your beers head automatically. From what we can tell there is some sort of spring loaded leaver in the handle connected to a disc in the bottom of the glass that must rattle about to cause the frothy goodness you see in the video above. The amusingly titled Beer Jug Jokki Hour is available soon from Japan trend shop, hit up the link below for a closer look.
