Yes, it is a real thing. It is yoga that is done with beer. It first originated in places like Berlin and Burning Man, and is now becoming the biggest thing in Australia.
According to BierYoga
founder Jhula, it is a marriage between two art forms, both of
which are great for one’s well-being. “BierYoga is fun, but it
is no joke,” said Jhula. “We take the philosophies of yoga and
pair it with the pleasure of beer-drinking to reach your highest
level of consciousness.”
