In Catalunya (European country under Spanish Administration),
the most ancient cups of sparkling wines are principled of century.
They are all "carved", that is to say, that they present
some cuts of considerable dimensions to hold the wire muzzle.
Thereinafter, around the end of the years sixty,
these cuts reduce its dimensions and give rise to a form of
plates that some call "shortened ", to differentiate
them of the previous.
Also we can find plates with lateral drills. These drills served
equally to hold the muzzles, and they are the last step before
arriving to the current plates.
In some cases, a small adjustment permitted that the same dies
that they had been used to manufacture carved plates are used
also to manufacture of normal.
Exists a reduced number of stamped plates that it are of would
be toward inside, they are the calls "plates recorded"
that, with some exceptions, tend be all of copper color.

The lithography process applied to the personalización
of the plates was begun to use in France at the beginning of
century. The plate of Champagne more ancient is that of "
vintage" 1906 of Pol Roger.
In Catalunya the system is much more recent. According
to all the consulted sources, the first photolithographed plate
that was manufactured in Catalunya was that of Codorniu of the
types "Baccus"of white and green color (n. 380). It
is of 1972 and served to seal a bottle of digs very special,
