Clipper teas produce a good organic green. Always use the leaves and not a bag, boil the water and let it stand for a minute or two and then use it. You can either put the leaves in a small infuser, or use a coffee percolator. As other replies have stated, it`s best not to make it too strong. The only way that I can drink it is by adding honey, about a teaspoon per mug. I`d also say not to try to drink it too hot, think of it more as a drink that you can sip over the course of half an hour or so...it`s fine as it cools.
It is an aquired taste and don`t be tempted by the ones that have other bits and bobs added, it does defeat the purpose!
