Storing Pu-erh

I am interested in collecting pu-erh tea cakes, and from what I've been reading, they say air flow, a constant temperature of 68F-85F, and a humidity of 30%-50% but not over 65% for more than a few days. Would a wine cooler work, or do they have some sort of special product that can store pu-erh? I am just being very cautious, because I don't want to ruin a bunch of perfectly good tea all because I did something wrong. Thanks!

Your humidity is way to low to the point where your puerh will dry out and be ruined. Constant airflow is also bad for puerh. Cloud recommends 20-30 degrees Celsius at 70%-80% humidity with slight air exchange.

The above is what I am using. Humidity 70% , fan circulation every other day and air exchange and rotation once a week.

How long have you been aging it like so? Thanks for sharing.

About 7 months now. I have an old refrigerator with shou in the lower part and sheng in the freezer part ( I copied this idea from Exempt). I have cigar humidifiers that keep the humidity at 70% . The fridge set very near to a central air vent that keeps it about 74 f or less. I have computer fans that move about 130 cfm in each section. Two up top and four in the bottom. The aroma is super nice when you open either section. Although I think I can learn a lot from you Tim. I am fairly new to this game for about 3 years or so and I try to learn something new every day. :D

Thanks for the info. Im also learning, so we are shareing the experience.

"The aroma is super nice when you open either section." What I have learned so far, what's gone, is gone. So if it smell super nice, those characters will be gone with the wind for good... Try to safe that as much as you can. If you are a cigar smoker, you will know what I mean.

Have fun ~ T

The aroma is still good I am not sure but I don't think it has decreased but i am hoping it will remain.

This is one of the reasons many people put their cakes into sealed plastic bags to preserve aroma and flavor. Exposure to air will deteriorate this just like with any other tea. It makes sense.

A lot of people (like Marshaln) believe that doing this stops or severely limits the aging process

Can you explain why would it stops or limits the aging process?

I am by no means any kind of expert in pu er.

Conventionally, from what I heard and seen, the cakes shouldn't be sealed in plastic bags. Just keeping it an airy and dry space away from sunlight will do. But, I suppose it could be quite different with your local climate and humidity.

I'm sorry but wrong wrong wrong wrong wrong wrong. Puerh needs humidity to keep the fermentation process going and constant airflow will make puerh loose all flavor and aroma.

As far as I'm aware puerh requires certain amounts of oxygen and airborne microbes to ferment. After a certain amount of time in a totally closed environment the necessary elements will be used or changed which will limit or stop the fermentation process.

Of course I don't know nearly as much about puerh as you so this may not be correct, however, I know Marshaln does not believe in sealing puerh and I respect his opinion as well.

Hmm, I've been invoked...

I don't think constant airflow is the answer. In fact, my storage has very little airflow. I don't believe in sealing the tea, at least not when they're young (when we have 20 years old cakes it's a different problem) but I think airflow is bad.

I store my tea in a cupboard with doors. I only open it when I need something from it. It's not like a fridge door or anything - it will allow a minimal amount of air to circulate, but that's it. In a place like Hong Kong a tight seal runs a very high risk of mold.

Your mileage may vary, depending on your location and climate, but airflow, from what I've seen so far, is never a good idea.
