In researching beer as it relates to the Jewish dietary laws, I came across this page, which states that most unflavoured beers are OK. Even imported beers are given a wary thumbs up, however the page repeats a curious warning that
Beer from New Zealand must be presumed Dairy unless stated otherwise.
What's special about New Zealand beer that we would assume that it contained dairy or dairy by-products by default, but imports from other countries do not?
