Wall Street Beer: This is the bar where the price of beer varies according to demand.

Investment and beer lovers have united at a unique bar in Qingdao Province, China . Like a Wall Street stock exchange, the Qingdao Beer Exchange is a bar that operates based on customer demand, although instead of stocks, it's the price of the beverage that rises or falls.

In total, the brewery has 30 taps with ten different types of beer. From classics to the most striking, infused with fruits like cherry, peach, or passion fruit. And all of them compete to be the most sought-after.

Everything is based on market movements: the more people order a specific beer, the higher its price will rise, and with it, the lower the prices of its other "competitors." In fact, everything is designed as if it were the stock market, because instead of a table with prices, there are large screens with all the movements. On these, you can see the increases in red and the decreases in blue, which are updated in real time.

Although there are limits to avoid problems. Therefore , prices can only fluctuate by 10% each day, and they return to their original state at the end of the day. However, each week, depending on sales, base prices can be temporarily lowered or raised by up to 20% of the original price.

"The process is simple yet exciting: grab a glass, scan the QR code, pour the beer, and watch the market change instantly . It's like being a beer trader," Li Chao, founder of the now-famous Qingdao "Beer Exchange," told China Daily.

And, as he confessed, the idea was born after seeing how famous the vending machines were in the country. Therefore, unlike the rest, he wanted to give it a more "exciting" touch. Something that has been more than achieved, since since it opened its doors in May, many have come to experience it. The beer exchange has received, as of June 2, a daily average of more than 10,000 visitors, and daily sales exceeded 1.2 million milliliters of beer.
