Overview
About Grape Syrup
Grape syrup is grape must boiled down until it is a thick dark sweetener, sold as petimezi in Greece, pekmez in Turkey and saba or vincotto in Italy.
Concentration is the entire trigger story. Grapes already carry more fructose than glucose, and reducing the juice several fold keeps that ratio while multiplying the dose per spoon, so grape syrup is graded high in excess fructose and high FODMAP. It is also a poor fit for low fermentation SIBO diets. Outside that one mechanism it is remarkably clean: low salicylate, low oxalate, low histamine, no polyols and no histamine liberation, so if you react to it, fructose malabsorption is the first thing to test rather than a broad sensitivity.

How Grape Syrup scores
Watch for
What trips people up
- High in excess fructose. Reducing grape must does not change the fructose to glucose ratio, it just concentrates it, so a tablespoon delivers what a large bunch of grapes would
- High FODMAP, and easy to underestimate because it is used as a drizzle rather than measured as a portion
- Poor fit for low fermentation SIBO protocols, since concentrated free fructose is rapidly fermentable
- Graded pro inflammatory and a poor fit for DASH, Mediterranean and AIP patterns despite the traditional, unrefined framing on the label
- Mild sulfite grade. Commercial grape products can carry residual sulfites from the fruit and processing, which is worth noting if you are sulfite sensitive, though it is not the main concern here

FAQ
Common questions about Grape Syrup
Is grape syrup low FODMAP?
No. Grape syrup is graded high FODMAP and high in excess fructose. Because it is poured rather than served in a measured portion, it is one of the easiest ways to take on a large fructose dose without noticing, particularly drizzled over yoghurt, pancakes or roasted vegetables.
Is grape syrup healthier than sugar for a sensitive gut?
Not on the trigger that matters. Table sugar is a balanced fructose and glucose pair, so the glucose helps carry the fructose across the gut wall. Grape syrup carries surplus free fructose with no matching glucose, which is precisely the situation that causes symptoms in fructose malabsorption. It is graded pro inflammatory too, so the traditional and unrefined label does not translate into a gentler sweetener here.
Does grape syrup contain sulfites?
It carries only a mild sulfite grade. Grapes naturally bring some sulfur compounds along and commercial processing can leave traces, so a highly sulfite sensitive person should check the label, but sulfites are a footnote next to the fructose load. Dried grape products such as raisins are the far bigger sulfite concern.
What is petimezi, pekmez, saba or vincotto?
They are regional names for the same thing: grape must, the freshly pressed juice with skins, simmered down to a syrup. Greek petimezi, Turkish pekmez and Italian saba and vincotto all predate refined sugar as the household sweetener in their cuisines. For trigger tracking they behave identically, so log any of them under grape syrup.
