This is a really nice tea. I am not a huge fan of gunpowder green tea, but the peppermint and spearmint come through really nicely. I like this tea cold brewed over heated. But, that is a personal choice.
Cold brew is a great way to drink tea. By not heating it, you are not releasing the tannins and you can add cold water over and over again. Also you retain more antioxidants than hot brew and also it releases only have the caffeine. I usually can add water 2-3 more times to my glass.
If I have bagged tea I do one bag per 8 oz of water. When I do the loose leaf in a pitcher, I generally eye ball it, but if you want something more specific go with 4 Tbsp per 1 quart.
