Altar Wine, also known as Church Wine, is an amber-red appearing wine with a medium sweet flavor. It is obtained from pure red grapes and meant for use in celebration of the Eucharist, commonly known as the Lord’s Supper or Holy Communion. Church wine is usually red to better symbolize the blood of Jesus Christ, as believed by members of the faith. Altar wine is sometimes mixed with a small quantity of water, symbolic of the mystery of Christ’s human and divine natures, his unity with the Church and the flow of blood and water from his side at death.
