1 gallon Coconut sap is the liquid extracted from coconut blossoms. It is locally called tuba, and is sweet when freshly harvested. Tuba can then be made into an alcoholic drink (raw coconut wine tuba or refined into lambanog), coco sugar or sukang tuba (coconut sap vinegar). Tuba is called bahalina (aged coconut red wine) that is darker in color and tastes and smells like a fruit red wine. A contaminated tuba will taste sour and becomes vinegar called sukang tuba (coconut vinegar).
