What type of wine is specified for use in Mass?

For the celebration of Mass, the use of wine is specifically mandated to be made from grapes and must be of good quality. This aligns with the tradition and theological significance that wine represents in the sacrament of the Eucharist, symbolizing the blood of Christ. The requirement is that the wine should be pure grape wine, which excludes wines that are blended with other ingredients or excessively processed.

Good quality wine is also emphasized because it needs to be suitable for sacramental use, which the congregation venerates. Using fortified or sweet dessert wines would not meet the specified requirements for the Eucharistic celebration as they do not adhere to the traditional norms established by the Church, which focus on authenticity and the essence of what wine is meant to represent in the context of Mass.

Thus, the proper answer reflects a theological and liturgical understanding of the significance of wine in religious ceremonies.
