There is Watch Disciple of Deokjin Yuk Onlineplenty of weird coffee out there, but this one takes the cake.

It's a so-called "smurf latte," available at a vegan café called Matcha Mylkbar in Melbourne, Australia. The bright blue colour in the coffee comes from a teaspoon of something called E3 live blue algae powder. Yes, algae.

The drink also contains lemon, ginger agave and coconut milk -- at this point, it's barely a coffee. So what does it taste like?

"People think it's going to be a bubble gummy sweet taste," the café's co-owner Nic Davidson told Mashable Australia. "You can definitely taste the agave and the lemon. It's a quite sweet and 'soury' kind of taste ... but it's a difficult to explain taste -- everyone thinks it's different."

The "smurf coffee" isn't actually on the café's menu, apart from a small sign that most people miss when they visit. Most of the hype has been growing on Instagram, where the café has been posting pictures of the coffee to much fanfare.

"It's been crazy. Over the weekend we've sold well over 100 of the lattes, and considering we're a small 40-seat cafe, it's a lot," Davidson said. "It's like our beetroot and mushroom lattes. We even have people who don't speak English ordering by just pointing to the photo on Instagram."

It's important to note the powder making the coffee blue and its various health claims haven't been approved by the U.S. Food and Drug Administration. Australia's Therapeutic Goods Administration has been contacted for comment.

In other words, don't expect your blue latte to suddenly turn you into a yoga guru.
