Question:
Answer:
Yes, white wine is valid and licit matter for the Eucharist. All that is required is that it be fermented grape wine that is unadulterated and unspoiled.
50. The wine that is used in the most sacred celebration of the Eucharistic sacrifice must be natural, from the fruit of the grape, pure and incorrupt, not mixed with other substances. . . . Great care should be taken so that the wine intended for the celebration of the Eucharist is well conserved and has not soured.
For valid and licit consecration vinum de vite, i.e., the pure juice of the grape naturally and properly fermented, is to be used. Wine made out of raisins, provided that from its color and taste it may be judged to be pure, may be used (Collect. S. C. de Prop. Fide, n. 705). It may be white or red, weak or strong, sweet or dry. Since the validity of the holy sacrifice, and the lawfulness of its celebration, require absolutely genuine wine, it becomes the serious obligation of the celebrant to procure only pure wines.
