Nice to meet you! I heard you're a beer fan. I also enjoy a beer now and again.
I see. Did you know for alcoholic drinks, beer is part of the oldest? It is also the third most drank drink overall.
Really? I don't know much about beer. Do you know where it was first invented?
It dates back to at least 5BC in Iran!

Beer is made from grains, cereal type like barley although others like corn or rice are used as well.
