Currants come from two main sources:

1. Zante currants (also called Corinth or Corinthian raisins) are dried tiny grapes from the Black Corinth grape cultivar originally associated with the Greek city of Corinth and the Ionian island of Zakynthos (Zante). These are dried fruits made from small, seedless grapes and historically traded from Greek islands.

2. Black, red, white, and pink currants are berries that grow on shrubs belonging to the genus Ribes. These currants are native to the northern latitudes of Europe, Asia, and North America. They grow in cool summer and cold winter climates such as Scandinavia, northern Europe, Russia, Poland, and parts of North America including New England and the Midwest in the U.S..

So, "currants" can mean either dried small grapes from Greece (Zante currants) or fresh berries from Ribes shrubs grown mostly in northern Europe and North America.
