These Lao Ban Zhang bricks are almost 2 years old now. They were stored in my home for most of the time, in a card board box in a cool temperature room. Moisture variation is seasonal, but never too low. Nine months ago, I transported them to my shop in PV, moisture is much higher here all year round.
Upper brick is stored on shelf (dark) with only paper wrapping. Brick is fluffy and leaves are easy to pick out.
Lower brick is stored in a porcelain box. Brick is still compact and solid.
After a tasting session, upper brick obviously aged faster than the lower, color is darker as well. However I like the taste of the lower brick better, it's more refined, less "rushed".
