If Nibiru was made out of 生ビール (fresh beer), it would be a very unusual planet indeed!
The surface of the planet would likely be covered in a layer of foamy beer, and the atmosphere would be filled with the aroma of hops and barley. It would be a very wet planet, with beer flowing in rivers and streams across its surface.
It is important to note, however, that a planet made entirely of beer would not be able to support life as we know it. While beer is made from natural ingredients such as water, grains, and hops, it does not contain the necessary nutrients and elements required for living organisms to thrive. Additionally, the extreme temperatures and conditions that exist in space would make it impossible for beer to exist in its liquid form for long periods of time.
Overall, while a planet made of 生ビール might be an interesting thought experiment, it is not a realistic possibility in our universe.
