A liquid sweetener pressed from the core of the blue agave plant, marketed as a natural alternative to honey and sugar — sweeter than table sugar, with a low glycemic index but high fructose content.
How it’s made
The blue agave plant — the same species used to make tequila — stores starches in its swollen heart (the piña). Producers cut down 7–10 year-old plants, slice off the leaves, and press or extract the heart’s sap. Heating the sap converts the inulin (a long-chain fructan) into a syrup of free fructose and glucose. Higher heat → darker syrup, deeper flavor.
A misleading reputation
Agave syrup gained traction in the 2000s as a “natural” alternative to refined sugar, marketed for its low glycemic index (because it’s mostly fructose, which doesn’t spike blood glucose). But the same fructose load is metabolized in the liver and has been linked to insulin resistance and fatty liver disease at high intakes. Nutritionally, agave syrup is closer to high-fructose corn syrup than to honey.
Use in the kitchen
About 1.5× sweeter than sugar — use less. Dissolves easily in cold drinks (it doesn’t crystallize like honey), making it popular for cocktails (margaritas especially) and iced coffee.
