I’m going to go ahead and post my comments here, although my sample is labeled Thurbo FTGFOP 1 CH (SPL) EX4 (Experts, I know FTGFOP, but can you help interpret the rest of the alphabet soup)?
I’ll have a longer review later also, like Jillian, but this is really good stuff. My favorite feature is the aroma of the steeped tea—-smells like the tray of communion cups at my church, or the inside of a Welch’s unsweetened grape juice bottle. This Darjeeling has personality!
My best guess about all those suffixes is that they indicate the number of a particular batch or something similar.
