Juan Collins is a refreshing cocktail made with tequila, lemon juice, simple syrup, and soda water. It is similar to a Tom Collins but with a Mexican twist. The tequila adds a unique flavor profile to the drink, while the lemon juice provides a tangy and citrusy taste. The simple syrup balances out the flavors and the soda water gives it a fizzy finish. It is a perfect drink for a hot summer day or for any occasion that calls for a refreshing and delicious cocktail.
