What is the difference between a geographical indication and a trademark?

A trademark is a sign used by an enterprise to distinguish its goods and services from those of other enterprises. It gives its owner the right to exclude others from using the trademark. A geographical indication tells consumers that a product is produced in a certain place and has certain characteristics that are due to that place of production. It may be used by all producers who make their products in the place designated by a geographical indication and whose products share typical qualities.
