French wines are considered the best in the world. One reason is because they have standards that wines must meet in order to be allowed to have certain titles on their labels. They also have a wide variety of grape growing climates. Each region of France has its own wine characteristics.
Port may be the most famous wine produced by Portugal, but it is in no way the only worthy wine. Notably, Madeira, another fortified wine like Port, is also from Portugal. Portugal also produces other varieties of red, white, and rose wines.
