Watch Online: The Yeast (2026)

A haunting Korean drama that blends family secrets with supernatural mystery, The Yeast (2026) promises to be a thought-provoking exploration of tradition, modernization, and the invisible forces that bind us to our past. Directed by Jang Dong-yoon, this 84-minute film from 1031 Studio delves into the unexpected consequences of abandoning heritage—literally and figuratively.

The Yeast (2026): A Family Secret Unravels

At its heart, The Yeast tells the story of eighteen-year-old Da-seul, who has devoted her life to helping her father maintain a traditional makgeolli (Korean rice wine) brewery. The family's craft is legendary among local villagers, but their operation remains underground because the origin of their 'nuruk'—the sacred yeast that gives their makgeolli its distinctive character—cannot be officially documented. This keeps them from legitimate distribution and relegates them to quiet, secretive sales within their community.

Everything changes when Da-seul's ambitious older brother, Da-hyeon, makes a fateful decision. In his quest to modernize the brewery and bring it into the legitimate market, he secretly discards the ancestral nuruk and replaces it with a commercially available alternative. He expects the switch to go unnoticed—but it doesn't. From that moment forward, Da-seul becomes mysteriously ill, insisting with eerie conviction that "the nuruk is gone." What begins as Da-hyeon's dismissal of her claims evolves into genuine concern as her condition deteriorates, forcing him on an unexpected journey that leads to abandoned places, encounters with homeless individuals, and ultimately, a reckoning with truths the family had long avoided.
