Product label contains single ingredient: Organic Concord Grape Juice.
Kof-K hechsher with no Pesach indication.
Kof-K website states:
Is the organic Juice Grape Juice from Lakewood Organics Mevushal? Is it fine for Kiddush? What about Pesach?
The Grape Juice is Mevushal - 180° F and can be used for Kiddush. It is not approved for Pesach as it contains an antifoaming agent which is not approved for Pesach.
I have called the company to learn what this antifoaming agent is, and could only leave a message. Has anyone else researched to know what this is?
