I have not seen the kosher Coke, but will keep an eye out for it. About 20 years ago I was on vacation in Mexico, taking a day trip on a tour bus. For refreshments they served us Coke. The first sip brought it all back, a real taste memory that slammed the senses back in time and made me realize why I had seldom drunk Coke in the intervening years.
The Home Depot stores around here (TX) have the Mexican Cokes.
