Definition: Line (of corks)

An old unit of measurement equal to 2.2 mm, still used to determine the length of corks. Thus, a 21-line cork is 48 millimetres long.

To date, no machine has been able to replace the discerning eye of a human being. Corks are therefore sorted by hand into different categories.

The width of the corks is always 24 mm. The height varies between 38 mm for the smallest corks and 49 mm for wines intended for ageing, such as Bordeaux. In Italy, however, some producers use corks that are 54 mm high. For a rare fine wine, one owner requires 60 mm corks.
