Martha's Wines is a company owned by the Portuguese Marta family; a family with a long history devoted to Port wine production in the Douro region. Their oldest vineyard belongs to the family since 1727. Originally the grapes were sold to other wine producers – but since six generations the Marta’s produce their own exquisite Port wines.

The current generations started expanding the family business internationally, but the production process from growing the grapes to bottling is still done within the family.
