What Is the History of Chaya Kadas in Kerala? Was There Anything Before Them?

Chaya Kadas (tea shops) are an integral part of Kerala’s culture, serving as a daily gathering place for people from all walks of life. But From what I understand, coffee-tea wasn’t even common in Kerala during the 1800s. Most people had never heard of it, and traditional drinks like കഞ്ഞി , മോര് and maybe few herbal drinks were popular. The British introduced tea plantations in Munnar, but it was mainly for export. So, when did the first Chaya Kadas start appearing? What were people drinking before tea became common? Were there similar gathering spots before tea shops became a thing?
