Yes, it does. Salts have different chemical structures, flavor profiles, and dissolvability, which can change the density of the brine. One tablespoon of Kosher salt is not the same as one tablespoon of table salt. Using a larger crystal salt like Kosher salt is key to getting the water ratio for brine correct. A rule of thumb is one cup of kosher salt for every gallon of water. Kosher salt is also less salty and contains less sodium than table salt or sea salt, which is why it's essential to use the right salt.
