Worried that my stash has been too dry since... well always, I've not been looking forward to waiting around 20 years until I start tasting some of my now young teas. I've heard that a decent humidity level for pu-erh is 70%. Is this true? Anyone experience good long-term results with this? If so, then I came across something interesting. Perusing some cigar enthusiast forums on the subject of humidity, I came across some of the usual stuff we talk about such as hygrometers, salt tests, etc. However, I saw something that stood out to me. They were talking about "humidity beads", and apparently these are little see-through pellets that regulate the humidity very accurately in a small storage space. You can't have too many beads, as it regulates the moisture content of the air around it. They come in (so far only able to find) two levels, 65% and 70%. I couldn't find the 65% super cheap on eBay, so I sprang for a half pound of the 70% for a very very cheap price.
I guess all you have to do with these is spray 3/4 of the beads with distilled (distilled water ONLY, I guess this is extremely important or the beads won't work) water until the 3/4 you sprayed are see-through, then when they become milky white you just spray them again. These cigar fans are saying this stuff is so accurate that they only use hygrometers to check when they have to spray their beads again!
What do you guys think of all this business, and what are your thoughts on ideal humidity levels for pu-erh storage?
