MULTI-PIECE CORK -There are two or more pieces of cork glued together. The cork comes from planks of low thickness which give the cork a high density. It’s usually made with cork scraps. This type of cork is used for larger bottles that don’t need aging.

It’s used for medium aging still wines (max 3 years).
