Xino Nero (Greek: Ξινό Νερό, before 1926: Εξί Σού – Exi Sou;[2] Turkish: Ekşi Su; or alternatively Gorno Varbeni Macedonian: Горно Врбени; Bulgarian: Горно Върбени) is a village in the municipality Amyntaio, within the regional unit of Florina.

[citation needed] The highest point in the area has an elevation of 920 meters and is 1.8 km northwest of Xinó Neró.

[9] In fieldwork done by anthropologist Riki Van Boeschoten in late 1993, Xino Nero was populated by Slavophones.

In the village, the dialects of the Eastern South Slavic languages were introduced after the middle of the 19th century, a fact that made it the target of the Bulgarian claims.

[citation needed]Scientific research has exacerbated the healing effect of this water, mainly on the kidneys but also on the liver of humans.

This pleasant acidic property and the presence in normal proportions of calcium and magnesium salts classify them in the category of very important mineral waters.

The factor that makes Xino Nero famous all over Greece, is the carnival events that take place every year at the end of February and the beginning of March.

Officially, however, they start next Thursday with a dance in the village square and a competition for the best costume at the group level.

The same happens on Friday and Saturday while on Sunday at noon the parade of chariots and hikers is held that many times the members of each group are over twenty!
