How real is your bubble tea love? Japan's tapioca beer puts it to the test.

Japan is right in the midst of a bubble tea boom, with lines pouring out of what seems to be a constant stream of newly opened boba shops. Fans of the drink have even taken to making panda shaped pearl milk tea at home, so it's no surprise to see some of kawaii spins on bubble tea. What has been surprising many, however, is the existence of tapioca beer, as pointed out by German beer fan Luka Reineke.

Although simply joking, he's not the only one surprised to learn of the tapioca and beer fusion, as many in Japan have been heading to beer cafe chain iBEER LE SUN PALM to try the mysterious concoction.

The drink, called "Tapioca the Next, Tapioca Beer" is actually inspired by the panaché cocktail, a mixture of beer and citrusy soda. It's available in regular, strawberry, pineapple, and kiwi flavors.

If you're craving some fizz with your tapioca, iBEER LE SUN PALM also offers the same flavors available as non alcoholic soda or with milk.

It may be a bridge too far to cross for some boba fans, but it looks like it may have found a home at Japanese Oktoberfest events.
