05 May KASHRUS QUESTIONS OF THE WEEK WITH RABBI MOSHE ELEFANT

Cow-Free Milk
A New Era in the World of Kashrut
What is “New Milk”?
“New Milk” is a dairy-free product made using a yeast-based
fermentation process. This process produces proteins that are identical to those found
in cow’s milk. Although no cows are involved at any stage, the final product looks, tastes,
and performs like real milk in coffee, cooking, and baking.
Is it considered pareve, and why?
When certified by a reliable kashrus agency, this milk is classified as pareve because
it contains no actual material derived from a cow. Even though the proteins are
structurally identical to dairy proteins, they are created entirely through fermentation
in a laboratory setting.
What makes this product different from regular plant-based milk?
Unlike almond or oat milk, “New Milk” contains real milk proteins, just not sourced
from animals. This allows it to behave like conventional dairy milk in taste, texture, and
cooking performance.
What is the status of kosher certification?
As of now, OU Kosher certifies only “Freemilk” from Strive Nutrition.
What is the concern of marit ayin?
Since the product looks identical to real milk, there is a concern of marit ayin—meaning
others might think someone is mixing meat and dairy. Proper labeling and branding are
important so people understand it is not actual dairy milk.

Can it be used with meat?
From a strictly halachic
standpoint, this product
may be consumed with
meat. However, some
rabbinic authorities suggest
being mindful of traditional
practice and public
perception when doing so.
Are there any practical
guidelines for use?
Some rabbanim recommend
placing the original bottle
on the table when serving
or cooking it with meat. This
helps prevent confusion and
clarifies that the product is
not regular dairy milk.
Why is this considered a
turning point in kashrus?
“New Milk” represents a major intersection of modern food technology and halachic
tradition. Its status and usage will continue to develop as rabbinic authorities evaluate
the implications and as public familiarity grows.
