For some Mashgichim like Rabbi Akiva Niehaus (Director of Kashrus Operations at the cRc and the Rabbinic Coordinator of the Liquor Industry at the cRc), it is a year round worry. If the owner of a liquor company is Jewish, there can be some serious concerns in regard to aged liquor. Specifically when it comes to bourbon, there are a surprising amount of Jewish-owned distilleries.
