I'm surprised there are so many younger people! Pretty impressive.
I'm 26. I started drinking probably around 8 or 9? I used to brew up the crummy "Good Taste Tea" that came from the local Chinese takeout place whenever my family would get Chinese food. During Middle School, band and choir rehearsed BEFORE school so I had to get up at 5AM. I needed a "pick-me-up," but my mom felt that I was too young for coffee, so let me have a cup of tea with breakfast instead.
After finishing all of the Lipton tea, I started picking out more varied bagged teas from the grocery store.
Then at some point a local pharmacy/gift shop was liquidating the gift shop portion of their business so I bought a LOT of RoT teas for $2-3/can. That marked my foray into loose tea.
I always had tea on hand during my college years, but I didn't drink it very often for lack of decent brewing equipment and the time and inclination to drink much tea.
At work, my team would get a cup of coffee every so often. One day someone said "I think I'm going to have a cup of tea for a change." We all thought tea sounded good, so we had a cup that day and since then we rarely drink coffee anymore.
Adagio has since become the official tea supplier for my team.
