Green tea is a staple for me. Today I picked up some hibiscus and dandelion tea. Very tasty!
I have a nice herbal blend, made from all native herbs and spices, that I use for Native American cooking demonstrations. Juniper Berries, Rose Hips, Peppermint, Red Raspberry and Red Clover. I grind the mixture in a mortar and pestle to break up the hard rose hips and berries. Nice bright - balance flavor, a soothing caffeine-free beverage. Good hot or cold.
I do both caf and herbal teas - the first before noon, the latter throughout the rest of the day. Around two gallons a day. Mostly Lemon and Wild Berry Zinger, and Black Cherry Berry. During the summer I mix them with some lemonaid. Recently I tried Green Strawberry Basil and was surprised how much I like it.
