Toward the end of the 1980s, Walter Fortunato designed and built the stopper sealing system that made WAF famous around the world. The Block WAF System still represents the most ingenious invention for the preservation over time of the precious characteristics of sparkling wines just uncorked.
Carbon dioxide released from the sparkling wine enters the elastic seal through the hole below. As the pressure increases, the seal expands against the glass wall creating a state of overpressure inside. As a result of this pressure, the external fixing bracket has been designed to counter the vertical thrust acting on the stopper, therefore guaranteeing its seal. Tested up to 6 atmospheres (88 psi).
