Start by preparing your glass. Fill a highball glass or a large rocks glass generously with ice cubes.
Add the Blanco Tequila to the glass. For an authentic taste, opt for a good quality 100% agave tequila.
Next, pour in the freshly squeezed lime juice. Fresh is key here – bottled juice just won't give you that vibrant, zesty kick.
Top off the glass with your chosen sparkling water. Topo Chico is the traditional choice for its crisp carbonation, but any good quality sparkling mineral water will work.
Gently stir the ingredients with a bar spoon to combine, being careful not to lose too much carbonation.
Garnish with a fresh lime wedge. Squeeze it slightly over the drink before dropping it in for an extra burst of aroma and flavor.
