Jewish Festivals: Kiddush: Borei Pri HaGafen after Drinking Kiddush Wine and Hesech Da'at

If you said or heard the blessing borei pri ha'gafen, finished drinking had hesech da'at, and then want to make a new blessing over the remaining wine in the cup, see Borei Pri HaGafen: Saying Again.
Note Although you may say a new borei pri ha'gafen on wine (or grape juice) that you left off drinking and returned to finish after hesech da'at, you may do so only as a simple blessing, not as kiddush (for how to make kiddush on same wine, see next halacha).
