What your referring to could be a "Dong Pian" tea (http://teamasters.blogspot.com/2009/02/ ... rvest.html
). This is a late winter harvest tea that characteristically takes place after the initial winter/fall harvest, around December. It usually, comparably speaking, has a different taste profile than the earlier winter harvest tea. One tea acquaintance I know in Taizhong,Taiwan absolutely doesn't care for it and others I know enjoy it.
Taiwanese often say that winter/fall teas, compared to spring, are comparably "gam gam" ( and have a deeper huigan than spring teas and are often less fruity. Among my friends in Taiwan whom are skilled tea drinkers, most often, the winter harvest teas are preferred over the spring teas. I can't tell you how many Taiwanese tea friends have expressed this to me. It is also my general preference too. Philip Brook of Taiwan Tea Crafts once expressed to me his favoritism toward the winter harvest in regards to gao shan tea. But, every year and every harvest is different.
For example, I was just this past weekend having tea with a gentleman whom has his own tea plantations in Taiwan and he confirmed for me what I have been hearing everywhere...basically, this winter was a rough winter for the tea harvest. The weather wasn't right. He has his own shipping company and is just now getting his full shipment of winter teas, possibly today or yesterday, from Taiwan. I also sat with a second Taiwan tea grower this past weekend whom said the same thing about the winter harvest. The second grower has farms in Thailand, China, and Taiwan though and can offset some of the harvest variation. It's my recollection that Tony of Origin tea mentioned in the forum as well that the winter harvest tea was challenged and, due to weather, in shorter supply, as well as more expensive. It could be, with things be warmer this winter that there will be a bigger Dong Pian harvest this year or that growers whom had a poor harvest during the fall can recoup some of the potential losses with the Dong Pian harvest.
Edit: Forgot to put the Mandarin in for anyone who wants to search it further: （Dong1 Pian4/"winter flake/leaf"/冬片).
