2 oz Tequila (substitute with Mezcal for a smokier flavor profile)
1.5 oz Grapefruit Juice
1/2 oz Lime Juice
1/2 oz agave nectar
2 oz Soda water (or grapefruit soda)
Combine all ingredients, except for the soda water, into a cocktail shaker and add ice. Shake the cocktail for 7-10 seconds until properly chilled and diluted. Strain the cocktail into a glass over ice, and top with soda water (or grapefruit soda). Garnish with a grapefruit wedge and lime wheel. Cheers!
