Shelf life: 3yrs. Non Centrifugal Sugar The way cane sugar is supposed to be, Just Panela cane sugar is hand cut, hand kettled, hand crafted. That means no industrial collection or processing. Just Panela cane sugar retains the natural characteristics, knows as “terroir” (pronounced; ‘ter-war’). This means a product of nature retains its taste from the soil, climate, and region from whence it came. When white, turbinado, and brown sugars are centrifugally refined the good is thrown out with the bad. That includes the naturally occurring vitamins, minerals, and amino acids.
