Definitely COFFEE, and like you - I drink it black (with an added tot of Brandy). Tea I won't touch at all - errgh yuk !!!
Having worked at a pub in her younger days my late mother rarely drank alcohol. But in the winter she always sneaked a tot of whiskey into her first cup of tea in the morning to keep her warm while she was lighting the coal fires. She could remember her mother doing the same when she was a child back in 1903.
98% tea 2% coffee in my case. Jane has never drunk coffee and all 3 of our children drink roughly the same ratio as me.
I tend to drink Tea at home - but Coffee when away from it. - Tea/Tea bags can differ when ordering out (Fruit/flavoured can be the exceotion) so like to know what kind and for how long the fusion brewd, so easier to have control thereof - Coffee and their different strengths may fall into the same category but generally the types have a standard taste - so that (with/without 'additional flavoring' ) Coffee is my external keeper upper
