What Flavor Is Grenadine?

The word comes from grenade, French for pomegranate. Grenadine began as pomegranate juice cooked with sugar. It reached American bars in the 19th century, and it has been drifting away from the fruit ever since.

What pomegranate grenadine tastes like

Made from the fruit, it is sweet first, then tart, with a slight dry grip at the end. That grip is astringency — your mouth going dry and rough, the way it does with strong tea. It comes from pomegranate's tannins.

The aroma is quieter than you might expect. Researchers find green, grassy notes in pomegranate juice from compounds such as hexanal and (Z)-3-hexen-1-ol, plus some floral linalool and general fruitiness.³ Cook the juice into a syrup and much of that fresh layer goes. What is left is mostly sugar, acid and the tannic edge.

What is in the bottle instead

Rose's, the best-known US brand, lists high fructose corn syrup, water, citric acid, sodium citrate, sodium benzoate, Red 40, natural and artificial flavors, and Blue 1.¹ There is no pomegranate on the list.

This is not new. The first US grenadine patent, granted to Victor Rillet in 1869, used real fermented pomegranates. Competitors undercut it fast. By 1891 a trade journal was complaining about imitations, and most late-19th-century recipes used little or no pomegranate.²

So there are two honest answers to the question. Bar-quality grenadine tastes of tart pomegranate. Supermarket grenadine tastes of sweet red fruit, nearer to cherry or raspberry candy. Most people who grew up on Shirley Temples only know the second one.

Building a grenadine-type product

Decide which grenadine you mean. If your customer expects the Shirley Temple taste, real pomegranate reads as sour and wrong. If you sell to bartenders, the candy version reads as cheap. Settle this before you brief a flavor house.

The candy version is a red-fruit blend. Most lean on cherry and raspberry. A cherry lean usually means benzaldehyde, the same compound behind the almond note in amaretto. Keep it low, or the syrup starts to taste of cough medicine.

Real pomegranate needs help. Juice concentrate brings tartness and body but little aroma, so most pomegranate products top it up with a natural flavor. Add a little more citric acid than you think. At syrup strength, sugar buries the tartness.

Color is half the job. Grenadine is used as much for its red as its taste. It is dense with sugar, so it sinks in a glass, which is how a Tequila Sunrise gets its layers. It is also one of the easy ways to turn a drink pink, as in pink lemonade. Pomegranate's own red comes from anthocyanins, plant pigments that shift with pH and fade with heat and light. That is why the big brands use Red 40. Rose's also lists Blue 1, last on the list, which deepens the shade.

In April 2025 the FDA said it would work with industry to eliminate Red 40, Blue 1 and four other petroleum-based dyes.⁴ If you are launching a grenadine now, plan the color before the flavor.

The labeling catch

If you put pomegranate on the front of the pack and the taste comes from flavoring rather than juice, US rules generally require "flavored" wording next to the name, such as "pomegranate flavored". Any artificial component makes it "artificially flavored". The natural flavor vs WONF guide covers which wording applies.

One limit to keep in mind: even an all-pomegranate grenadine does not taste strongly of pomegranate. The fruit's aroma is faint, and sugar at syrup strength flattens it further. If your brief says "unmistakably pomegranate", you will need flavor support whatever the juice content.
