On a hot shabbos, I would like to put some ice into my kiddush wine/grape juice to cool it. What halachic issues would be involved and what are the views?
1] Does the solid ice contribute to the required volume of the wine/ice mixture? I saw in Shemiras Shabbos Kehilchoso that the ice does not contribute the required volume (can't find it now).
2] Is there a problem with the dilution of the wine or grape juice? My friends tell me that our wines can be diluted up to one-third with water. But I have seen that there are wines that will not tolerate any dilution.
