I love brewing various teas in my gaiwan at home, such as white teas, green, oolong, black etc. However I work/play outside a lot and sometimes just need a big mug of gulpable refreshing/calming tea, and a lot of the teas I have been collecting seem more suitable for savoring slowly.
Obviously gaiwan is not the tool for the job here, so probably something for an infuser mug...
Any recommendations on teas for pure refreshment?
