The Holy See
clearly forbids the practice of pouring the Precious Blood as others have shown but then we are treated to this famous quote from the cardinal of my eccelsial province:
*"…Some have inquired about the continued use of specially designed carafes in which the wine is presented at the Preparation of the Gifts, placed upon the altar, consecrated during the Eucharistic Prayer, and then distributed into smaller chalices for Holy Communion. Our overwhelming experience with this practice over the years has been most positive.
Because our practice has become an Archdiocesan custom of over seven years, with both the Catholic faithful and the ministers accustomed to this practice,
I am willing to grant exceptions to no. 106 of Redemptionis Sacramentum* for legitimate reasons, such as the following: where the altar table is too small to accommodate many chalices, thus creating a greater danger for spillage; and where the number of chalices is so large that they would visibly detract from the important sign of One Bread and One Cup, as well as increase the danger of tipping over the chalices…"

Which translates into “we are going to do whatever we want.” This gets so darned old…
