Although an agave plant is cactus-like it belongs with the same family of Lilies and Aloes, and is of the family of Agavaceae. The nectar from which tequila is produced comes from the blue agave. It is from this agave that many farmers harvest the finest nectar in the world. This isn't an easy process. However, the countless beneficial qualities of the agave nectar makes it worthwhile to harvest. Agave nectar is so versatile that not only is it taken for medicinal purposes, but is also used as an additive for delicious desserts.
Identify the madre(mother) among the agave plants. The madre or mother is the mature agave plant from where nectar is to be harvested. The madre agave plants have already reached the height of about seven to 12 feet.
Shear off the thorns from the leaves of the agave plant. Use a machete to do this. Cut from the bottom of the leaf all the way up to the tip. Do this to all the leaves that you will come in contact with as you get your way to the center of the plant.
Cut the leaves surrounding the center until you get to the center of the plant. You will find a long bulb like in the center of the plant. Do not try to pull it with your hands. Instead, use the machete and cut it from the bottom. As you peel leaves from the center you will then find a long white stalk called as Corazon or heart. Pull it towards you and set that aside. It weighs about 36 to 75 kilos.
Dig the base of the agave plant. Use the machete to take the hard surface of the base. You may use the ladle or a trowel as the spade and dig deep. Take the white meat out until you see juice coming out from the hole where the heart used to be.
Wait until the juice or nectar comes out from the hole. When the hole has been filled you may then use the siphon to get the nectar out of the hole. As you transfer the nectar to a bucket or a container use the strainer to filter the nectar.
