There are a number of manufactured fruit drinks that have trace amounts of grape juice that are less than 1/60 of the volume of ingredients. (A way to tell is when the product label states the percentage of grape juice.)
This Star_K article says:
Avoda Zara – An idol, or anything used in the service of idolatry including wine,31 is not batel.
But Note 31, there says:
This is known as yayin nesech. For conditions and details, see Y.D. 134. Note that the halachos of wine that is prepared or touched by an akum (stam yaynam) are different.
So, my question - Considering that the grapes are most likely pressed by machinery in the processing plant, it's doubtful that a Gentile has touched the grape juice at all. Would this, then be considered stam yaynam, or what? In short, can a Jew drink this juice product?
Assuming that the grapes were pressed by non-Jews, can Jews use the product if the juice is less than 1/60 of the volume?
