From Red Boat - "The Phamily Reserve 50N Hardwood Smoked is a collaboration between Red Boat and Blis Gourmet. At 50N this is the highest grade fish sauce in our lineup. After our initial fermentation process to create the fish sauce, it then gets aged in barrels that previously held bourbon and maple syrup, and then it gets smoked in a combination of mesquite, hickory and cherry wood. The end result is a subtle sweetness and smokiness not found in other fish sauces! No preservatives. No MSG. Just anchovies and sea salt for unsurpassed quality and flavor."
