Consecrated wine

In Paul Turner's Blog by Paul Turner

Q: Is there precedent for conserving left over precious blood in a sealed decanter in the tabernacle if the guesstimate for how much wine was needed for consecration is wide of the mark? This issue pertains also to alcohol limit driving laws and/or when the priest, extraordinary ministers of communion or congregants do not wish to consume the remaining contents of the chalice. In other words, can the precious blood be conserved, together with the consecrated hosts in a tabernacle to be consumed at the next Mass or Communion Service?

A: No, there is no precedent and no permission. I’m not sure why. Perhaps it’s fear of spoiling. Or just that we went so many centuries without even thinking about the problem.

The consecrated contents are to be consumed
