Saying Borei Pri HaGafen Again

You may say a new blessing on any remaining wine if:
  • You said, or heard someone saying, borei pri ha'gafen,
  • Drank some wine (or grape juice),
  • Decided to stop drinking (hesech da'at), and
  • Returned to drink from the same cup later.
Note If you are not sure you had hesech da'at, do not say a new blessing.
