I mostly drink yanchas/Wuyi rock oolongs. Get them from various sources, no specific brand. Also occasionally reputable sheng pu-erh if I can afford some, non-pu fermented teas, jin jun mei, genmaicha, or anything Nepalese or Malawi whole-ish leaf, in small quantities (max 50g).
Barry’s, speaking as a non-Irish person who loves the idea of two competing tea brands and hasn’t even tried Lyon’s.
Agreed on Yunnan on all but shu, and sheng at the temperamental ~5-10 age range.
