From the producer:

"The ubiquitous cherry-red bottle of syrup holding court at every bar, modern grenadine is a far cry from its pomegranate origins. Many cultures enjoy pomegranate juice when it is available, as did early bartenders in America and abroad. Rest assured, they were not using high-fructose corn syrup colored with red #40. Our grenadine is made from pomegranates and cane sugar; no water or other ingredients added. The bright acidity and tannic backbone of this syrup will transform any drink that uses it."
