Haitian Kleren (or clairin) is a potent, unrefined cane spirit integral to Haitian Vodou, serving as a sacred offering to spirits (Lwa) and ancestors to facilitate communication, protection, and spiritual cleansing. It is used in rituals to remove negative energy, empower ceremonies, and honor the Lwa. 
 
Spiritual Benefits and Uses in Vodou
Offerings and Communion: Kleren is frequently poured on the ground or in vessels as a direct offering to the Lwa and ancestors. It is consumed in small sips by practitioners and Houngans (priests) to create a bond with the spirits.
Cleansing and Protection: It is used to clear negative energy, purify spaces, and provide spiritual protection.
Ritual Fuel: As a "sacramental liquor," it is considered essential for fueling dancing, rituals, and ceremonies.
Healing and Empowerment: Beyond spiritual use, it is often mixed with herbs to create medicinal tinctures for both physical and spiritual ailments.
Cultural Connection: The spirit is deeply tied to Haitian history, representing freedom, resilience against persecution, and connection to the land (terroir). 
Kleren is often considered a "cool" agent, despite its high proof, aiding in restoring balance and harmony to life.
