Shincha cometh ... after a long hard winter for most of us (that is not yet over)! Some of the earliest selections begin trickling into availability sometime from mid April or later ... and occasionally a little earlier. Earliest is NOT necessarily the best, in fact it usually is not ... it is simply a marketing thing getting a very early picking to market ... similar to Darjeeling first flush.
I think I have sampled at least 20 shincha selections each year since I have been drinking sencha. I guess you can say I am into it.
We also usually have a Shincha OTTI round or two on TeaChat featuring excellent vendors. You can check out the OTTI/NOTTI forum for past rounds.
And then there are the annual Shincha Ordering Topic and Shincha Review topics in this forum.
