Cold days and hot kettles

My favorite part of winter, and least favorite part of summer, are the exact same thing.  The heat that is generated while brewing tea.  So as the weather really turns ugly outside, I am once again incredibly fond of turning on the kettle to do long marathon brewing sessions.  In terms of tea selection, I naturally seem to gravitate more towards the teas that require boiling water to prepare and drink, except for the really odd ball out multiple times a week cravings I get for gyokuro.
