The shanks of Spark Top 1 corks are individually moulded from steam treated and controlled granules of Amorim’s own grinding operation.
This moulding agglomeration process is the best to assure adequate density and specific weight of each cork. Shanks are tested in process for gas loss resistance. Before being assembling to the cork shank, the natural cork disc is sanitised in a cleaning system steam-based, which also extracts volatile compounds.
Amorim’s Spark Top 1 is recommended for quality sparkling wines with ageing potential less than 18 months.
