Question: What's the difference between kosher wine and kosher for Passover wine?
Answer: In order for a wine to be kosher, it must be created under a rabbi's immediate supervision, with only Sabbath-observant Jewish males touching the grapes from the crushing phase through the bottling.
While all wines require some sort of mold (yeast) for fermentation, kosher for Passover wine must be made from a mold that has not been grown on bread (such as sugar or fruit) and must exclude several common preservatives, like potassium sorbate.
All Israeli wines are Kosher for Passover and most (but not all) kosher wines are kosher for Passover. To be sure, check the label for the P.
