Place the firm coconut oil and white sugar in the bowl of a stand mixer fitted with a paddle attachment. Mix together on low speed, until a thick paste is formed. Add the grapefruit zest, grapefruit juice, peppermint and grapefruit oil, and beet juice, if desired, to the mixture. Mix on low until incorporated and then turn the speed up to medium for about 20 seconds, or until mixture is well blended and fluffy. Store in an air-tight glass jar in the refrigerator.
