Tea tasting parties, like many other social events for foodies, have an internal language and dynamics of their own.
This reminds me of how people are so fixed on cold brew coffee and other coffee production methods today. I know this is mentioned later on in the lecture notes, but I still thought I'd mention it. It also remind me of how some people are into craft beer and beer tasting. A lot of what makes a commodity popular is how the public views it and talks about it, and if it is trendy or not.
