What to know 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.
Watch for
- 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
