Xinovrysi (Greek: Ξινόβρυση, before 1927: Μπεστίνικα - Bestinika[2]) is a village in the Pelion area in Magnesia, Greece.

[2] The historian Yannis Kordatos describes the origin of the name Bistinika that comes from the Slavic word pestinik or pecnik which means oven.

In the mid-19th century, the village had 65 to 80 houses and around 325 inhabitants, cultivating olives, grapes, figs and fruits.

Besides Argalasti and Bestinika the municipality also contained the villages Metochi, Bir [Μπιρ] (now Kallithea) and Ski [Σκι] (now Syki).

Its nearby beaches at the Aegean Sea (Mourtitsa, Potistika, Kourites and Melani) have been attracting tourists.
