You still have to pay for it because it costs money to make. But it’s completely open-source beer so you can recreate it yourself if you don’t want to buy it pre-made, or you want to modify the recipe.
I have no idea how to make beer otherwise I’d have a crack at this shitpost myself…
Just a fun fact here. The original name of the band Barenaked Ladies, was Free Beer. They were a pub band back then, and used posters to advertise themselves that read:
Tonight! One Night Only!
Free Beer!!!
