For decades, the standard kashrus assumption across the industry was that unflavored beers were generally kosher without requiring formal supervision due to their simple ingredients (water, hops, barley, yeast).
However, in recent years, major changes in the brewing world – including a surge in craft breweries, new production techniques, and flavored varieties – have made that assumption increasingly unreliable.
In response to these developments, Kashrus agencies have undertaken a major revision to beer kashrus guidelines. In a letter to food-service proprietors and mashgichim, the OU explained that the “rise of craft brewing and new production methods” has resulted in shared equipment, additives, and flavorings that can compromise kashrus even in products that appear simple.
The agency wrote that, after conducting extensive research and consulting with leading Kashrus agencies OK and Star-K, they concluded that the new realities necessitate a more stringent approach to ensure that Kosher standards are consistently met.
The letter noted that while many major national brands already have certification, all craft beers and specialty brews will now require a hechsher or written verification.
