From England, and just getting into tea!
Well my friend you have come to the right place, vast magnitudes of tea-knowledge inhabit this very forum.
BTW, some of my favorite black tea types are Assam, Golden Yunnan, and good Keemun, and China Fujian Reds, to be rather broad. If/as you get more into tea and cultivate your tastes, you will likely discover particular varieties and vendors that you enjoy.
Welcome and happy-tea-drinking
