Term for different qualities of a wine, although it is the same manufacturer and wine. The simple reason for this is that when maturing and storing wines, the ripening or aging process in the individual containers is never 100% identical. Especially when barrel aging
in smaller containers like for example barriques there is the phenomenon that (slightly) different wine qualities result. By leveling
(Mixing together) of containers before bottling
this will be compensated. But also in the bottle aging
Over time, different qualities can arise. Likewise wine faults
like the one corked
only occur in individual bottles.
