Corona Beer: Any pale Mexican beer such as Modelo Pacifico will also work.
Tequila: I like Jose Cuervo Especial tequila. Patron would be my second choice. Casamigos is also good.
Orange Juice: I prefer no pulp for a smoother drink.
Grenadine: Look for in the mixers aisle near the tonic water.
Tips
Pour Out Carefully: The halfway mark is at the top of the label on the bottle.
Adjust To Your Tastes: Add more or less grenadine, depending on how sweet and red you want your drink to be. Also, add it last for the gorgeous layered effect.
Keep Everything Ice Cold: Keep the beer in the fridge until you're ready to make this recipe.
Avoid stirring or shaking the drink since the beer is carbonated.
