Have you ever been to a brewery? I hear that they make beer and other fermented products.
Yes they're pretty cool, brewing beer goes all the way back to 2500 BC at least!
Wow its that old! that's amazing, I wonder if our ancient ancestors used the same brewing techniques we do today, Can you tell me more?
A similar process is used, but by the 9th century it was produced on a larger scale by monasteries and farms. Then dedicated breweries came about a few centuries later.
Interesting, So it took us a while to start producing it on a mass scale, How many breweries are there today? 
Hmm not sure sorry. There are plenty of huge international corporations today and lots of microbreweries so definitely at least thousands.
Yea id bet there is a lot today considering how popular beer and alcohol is. 
Yes China has actually been the world largest beer producer since 2001!
