From the producer: We use Mommenpop Ruby Grapefruit, Makrut Limepop, organic California grapefruit juice, and a dash of salt to bring you this crazy refreshing cocktail. Delightfully carbonated and begging for a warm summer day. Pop the cap, serve cold (straight from the bottle or poured over ice) and you’re good to go. A bubbly, zippy, can't-put-it-down cocktail.
