Agave nectar, also called agave syrup, is a sweet syrup made from the filtered juice of the agave plant native to Mexico. It can be prepared from agave salminskiy or from the blue agave plant, which is also used for making tequila.

To make the syrup, the agave juice is first extracted by grinding and pressing the collected leaves of the plant. The filtered juices are then heated to vaporize the water and break down the complex sugars into simple ones.
