Tea

Tea is amazing. Coffee can be pretty good (or even great, but I can't afford "great" coffee). I've been very impressed by tea though, because of two things:

1. It's amazingly portable. Anywhere there is a source of hot water tea can be made by the cup or gallon assuming one has a sufficient supply of tea. The best part is that tea comes by the bag and so it is easy to have not only sufficient, pre-measured tea on hand but a wide variety to chose from with minimal extra weight.
2. Good tea is still pretty cheap. Again, I've never had "great tea", but the run of the mill pre-bagged store-bought stuff like Bigalow, Celestial Seasonings, Salada, or Twinnings is all quite good and sells for less than $0.15/bag which means under $0.15 per cup prepared. I can only imagine what kind of pricing decent tea has when purchased in bulk.

Either way, it's good enough for me to drink at least a quart of the stuff per weekday, and sometimes a half gallon per day on weekends. Hmmm . . . tea.
