More nonsense. Almost all beer is kosher. Heineken in particular is known to be kosher, whether it has anything on the label to say so or not. Who gave the Rabbinate the right to “warn consumers and caterers to be certain they only acquire approved bottles”? Are “approved” bottles any more kosher than “unapproved” ones, or are they just part of the Full-Employment-For-Mashgichim industry?

This is seriously deficient. To start with, there is no such thing as “Smirnoff Ice Vodka”; whichever Rabbanut flunky wrote this alert made no effort to ascertain his facts, and thus has no credibility.

As for Irish whiskey, yes, one must know that a brand is kosher before using it (unlike whiskey from most countries, which can be presumed kosher unless known not to be). But there is no need for a certification on the label. That is just a made-up requirement of the Rabbanut, with no basis in halacha. If a particular brand is kosher then it’s kosher; there is no Irish distillery that makes both kosher and treif runs of the same whiskey. Paddy and Jameson’s are both definitely kosher; I’m not sure about Bushmills, but the company’s web site says it’s certified by the Irish Chief Rabbinate, and I see no reason to doubt it.
