Soju, Traditional Korean Rice Spirit

Soju is a traditional Korean rice spirit shaped by centuries of fermentation culture.

Historically distilled from makgeolli, a naturally fermented rice wine, traditional soju carries the flavor of grain and the aroma created by Nuruk, Korea's indigenous fermentation starter.
Unlike industrial neutral spirits, authentic distilled soju begins with rice fermentation. It reflects a deep relationship between craft, time, and raw ingredients. At its core, soju is not simply a drink, but an expression of Korean fermentation heritage.

Nuruk, The Foundation of Traditional Korean Fermentation

Made from grains and wild microorganisms, it forms a living ecosystem that converts starch into sugar and alcohol. This natural culture introduces variation, complexity, and character impossible to replicate with standardized industrial yeast.

The layered aroma and texture found in traditional Korean spirits originate from this fermentation ecology. Nuruk is not simply an ingredient, it represents a philosophy of working with nature rather than controlling it.

Onggi, Aging in Traditional Earthenware

Haru Soju is matured in onggi, traditional Korean earthenware vessels used for centuries in fermentation and storage. The porous structure of onggi allows gentle micro-oxygenation, softening the spirit while preserving clarity. This slow interaction with air adds depth without masking the natural character of the distillate.

Onggi has long been used to ferment foods such as kimchi and jang. By maturing spirits in earthenware, Haru Soju continues a lineage of Korean craft where time, clay, and air shape flavor naturally.

Haru Project

Haru Project produces traditional Korean distilled spirits in Europe, introducing Korean fermentation culture beyond its borders. Haru Soju is distilled in Germany by a Korean brewmaster graduated from the Technical University of Munich (TUM), combining Korean tradition with German brewing precision.

Haru project is shaped by both professional brewing knowledge and personal connections to Korean home fermentation, where memories of makgeolli brewed in family kitchens continue to inform the spirit.

We represents a dialogue between cultures, interpreting Korean fermentation knowledge through contemporary craftsmanship in Germany.
