I've been exploring the world of tea for about 5 years and have tried just over 200 teas of nearly all tea types. There is one tea that I've consistently gone back to since I have discovered it. It is a sheng puer from Yunnan Sourcing. I have an interesting relationship with this tea. I have never thought of this tea as wildly complex or as an experience. Instead, it has balance with just the right amount of intrigue to work as a daily drinker. I'm always happy to drink this tea.
Unsmoked lapsang souchong. The smoked variety is tea that tastes like liquid smoke, which is great, but if you drink it unsmoked, it's like a smooth, malty cocoa.
