Absolutey! Just add 1/6 pound of loose tea (herbal tea also) into the stainless filter and fill the brew chamber with cold water to the fill line. Cold brew for 12 hours, flip the BOD® over to drain and pour into the Extract Chamber for storage.
When you want to make a cup or glass of tea, hot or cold, just add 2 oz. of tea concentrate to 7 oz. of water to taste.
