Have you heard of homebrewing? Homebrewing is the process of brewing beer on a small scale for personal, non-commercial purposes. It also tastes better when its homemade. 
i've never heard of it. how do they brew beer at home?
They uses stills and machines used to boil and ferment different fruits and vegetables, Back in ancient times Laws against making alcohol were actually enacted and repealed between the Zhou and Ming dynasties. So homebrewing has a long history. 
that's really interesting! I didn't know you can make beer out of fruits and veggies
Indeed, a beer brewing country in England is known for its top fermented cask beer (also called real ale) which finishes maturing in the cellar of the pub rather than at the brewery and is served with only the best natural carbonation.
I bet people who like beer would love that one
I bet they would, Brewing isnt really that hard, the brewing process and fermentation of the starch sugars in the wort produces a fuel called ethanol and carbonation in the resulting beer. Homebrewed beer also has a higher alcohol level. 
My friends from Russia brew vodka at home. the process looks complicated
It just depends on what type of brewery you have, some machines are more complicated than they look, but it all comes down to the fermentation process. 
i think they actually made it, they didn't buy any special equipment
