WineFrog explains Estagio
Estagio is the process by which Madeira is aged following the long and elaborate stage of estufagem. During this period of estagio, the wine rests for a required minimum of ninety days. It is also required that these wines must not be commercialized or even bottled before the 31st of October following the second year after the harvest (vintage) year.
It is the estagio process which enhances robust character and allows for the characteristics created during estufagem to be embodied in the overall wine.
