In a shallow dish pour out 1/4 cup of kosher salt. Rim 6-8 low ball glasses with a lime wedge and dip in kosher salt.
In a large pitcher add all ingredients and stir for 30 seconds. *Note the agave nectar is totally to your preference! Some days I like a sweeter margarita and put the full cup of agave and other days I only like a small amount. Start out with 1-/3 -1/2 cup and taste test your way up.
Place the margarita batch into the fridge for 1-2 hours before serving or fill glasses with crushed ice. Serve!
