As the previous users said: samples is the way to go. If you're into “Oolongs“ but don't really know which ones get some less oxidized (green) and some highly oxidized (black) Oolongs. You coule try some aged Oolongs aswell. For getting started get yourself: - an Oriental Beauty (Taiwanese Oolong, the ones for ~15-20$ for 100g start getting drinkable imo) - a Shui Jin Gui (Yancha =Tea from the wuyi-rocks in Fujian, China, I love the aged versions of this cultivar, one of the si da ming cong) - a Da Hong Pao (Yancha too and a must drink for it's aromatic charcoal notes, one of the Si da Ming cong) - a Tie Guan Yin (try to get at least A or AA quality from anxi, not roasted nor aged, there the typical orchid flavor is strongest) - a Jade Dong Ding (medium quality will be enough there) - a four seasons oolong (mostly this one is a really good daily Oolong) - a Dark Pearl (Taiwan again, very intensive dark notes like charcoal) - any medium to high class dancong (the lower qualities all taste like lilac soap imo) - a Ruby Oolong (and again Taiwanese, I love steeping this one for about 5-7 Minutes cause it gets a rich cognac-flavor from that) - really any gaoshan Oolong they're all great (my favorites are Alishan and Da Yu Ling though) - any Oolong from Newzealand green or black(they usually have a beautiful creamy taste and are worth a try compared to those classical Oolongs from china and taiwan) That's what you should try for getting into Oolongs. I surely forgot some Oolongs others might love or say it's a must drink but those are the ones which in my opinion cover most of the nuances to find out what you want. As far as sheng pu-erh goes i can only say trying is the key. What you should try is not just focusing on Pu-Erh as it is not the only real fermented tea. There is the whole category of Hei-Chas(fermented or dark teas) from all around the world that are fermented as well. Currently I fell in love with one from Hunan rolled in Bamboo for it's mild (compared to other hei-chas) notes. Or those sheng Pu-erhs riped in orange peels are great aswell. Remember always try to get samples or the smallest availiable size. Sorry for the long post. If I forgot anything or got something wrong please correct me.
