What makes a spirit kosher or not? A breakdown of the laws.
"Kosher" or kashrut is the system of Jewish dietary laws, and they govern everything observant Jews eat or drink. The word kosher means "fit" or "proper," and when something is certified kosher it means that it's been checked, re-checked, and prepared or processed in a way that guarantees nothing improper was snuck in before it gets to the drinker or diner. Kosher food isn't "blessed" by a rabbi. It's watched and guarded by a mashgiach who's trained in all of the rules and makes sure they're followed.
