The world's religions have had different relationships with alcohol, reflecting diverse cultural, social, and religious practices across different traditions. While some religions strictly prohibit alcohol consumption, viewing it as sinful or harmful to spiritual and physical well-being, others incorporate it into their rituals and ceremonies. Throughout history, alcohol has held significant roles in religious observances, from the use of sacramental wine in Christian sacraments to the offering and moderate drinking of omiki in Shinto purification rituals.

Sacramental wine, Communion wine, altar wine, or wine for consecration is wine obtained from grapes and intended for use in celebration of the Eucharist. It is usually consumed after sacramental bread.
