Prep your produce. Wash apples and beet thoroughly.
Core apples if you prefer. Peel the ginger and the lemon. If using a juicer, cut everything into chunks that fit the chute.
If using a blender, chop into smaller pieces.
Juicer method. Feed the beet, apples, ginger, and lemon through the juicer. Stir the juice well to combine. Taste and adjust with extra lemon or a small slice more ginger if you like a stronger kick.
Blender method. Add chopped beet, apples, ginger, lemon, and water to the blender.
Blend on high until completely smooth, about 45–60 seconds. Strain through a fine-mesh sieve, nut milk bag, or cheesecloth for a smooth juice. Press or squeeze to extract as much liquid as possible.
Chill and serve. Pour over ice if you want it extra cold.
Stir before drinking to keep the color and flavor uniform.
Make it your own. If it’s too earthy, add half an apple. If too sweet, add more lemon. For more heat, add another 1/2 inch of ginger.
