I bought this tea back in 2015 and it was terrific. it was still drinking good until about 6 months ago and is now staring to loose it's flavor. pretty good for 3 1/2 years. You were out of stock for a long time. I was finally able to buy some in early 2018. I bought a 1lb. It was a little disappointing, but still good...but I know that teas change due to climate conditions. I guess this was from Spring 2017?? I have about 1/3 of a bag left and it's losing it's flavor. I bought smaller bags in Nov. of 2018 and just opened one. It hardly has a taste. The description just says that it was harvested early spring. Was that of 2018 or 2017? For most Taiwan Oolongs, Spring 2018 was an amazing harvest. The best since 2015. I will not buy this tea again unless I have the option to receive or buy a sample. It was my favorite tea from Silk Road. I no longer like buying teas unless I know the specific harvest season and date.
