Question:
In case I have a bottle of wine and used to make the kiddush last week, left wine in it can I use for the next Shabath to make the kiddush?
Answer:
You may use the remaining wine inside the bottle for kiddush this week.
As a side point, there is an idea, that the leftover wine from the kiddush cup which one drank from, is considered “pagum” (blemished). The way to get rid of this, is not to pour the wine back into the bottle directly, but to pour some wine from the bottle into the cup first and then pour the wine back into the bottle.
Best wishes
