We were in a state of shock when we realised how many chemicals were used in producing tea. With compromised health concerns in the family, we were really pleased with being able to get organic tea, and to top it off, it is wonderful delicious tea, the best tea we have had, and no crap chemicals to be concerned about......we love the tea, and so do the worms when they get they bags in the worm farm. We wonder though, does the caffeine in the tea keep the worms awake at night?
