I just ordered a full bing of 2001 Jin Chang Hao Yiwu from EOT. Here's what's I think is the way to start out but please let me know if there's a better way. I unwrap the bing and admire it. Then I gently pry off a chunk for brewing over the next month or so. Rewrap the bing in its wrapping paper, then in something that breathes, like a paper grocery bag. Store the bing out of the kitchen, away from light and odors. Brew the tea. Enjoy.
My sample was large enough for two sessions. My notes about the first session, which was two months ago, don't name the teapot. I enjoyed the tea, but wasn't planning on buying more. I used my Red Blossom Yixing for the second session and this time the tea was a pleasure to drink through 6 infusions yesterday and 6 more today. I stopped at 6 this afternoon only because I was developing a caffeine headache!
