Our Calamansi Essential Oil comes from Citrofortunella microcarpa grown here in the Philippines and extracted via the distillation method. We load up Calamansi peels in our distillation stills and after a few hours, we separate the Calamansi Essential Oil from the hydrosol. The result is a complex citrus aroma characteristically Calamansi like we know it as such. We use in-house distillers in getting the oil.
