the newly made baijiu is
pungent and spicy,
just like an adolescent.
by preserving it in the cave for years and
waiting for it to be “older” or “mature”,
it can become delicate, harmonious

luzhou laojiao has its three natural caves that are all ideal for storage of baijiu , namely chunyang cave, zuiweng cave and longquan cave.
the air in the caves flows extremely slowly and the temperature is stable at around 20 ℃ and the relative humidity at around 80% all year round. the constant temperature, humidity and abundant micro- organism varieties provide optimum conditions for the esterifying, aging and flavoring of baijiu body.
in the meantime, the surface of earthenware which is dotted with micropores of reticular structure can make the baijiu breathe and interact with the air outside and the interaction is vital for eliminating the substances that cause baijiu to taste pungent and spicy.
now the 3 natural storage caves are taking care of the “new-born” baijiu of luzhou laojiao, protecting it like parents.
