To make elderberry juice, add 2 cups of fresh elderberries to a small pot with 1 cup of water.
Boil the elderberries and water for 10 minutes with the lid on.
After 10 minutes, most of the elderberries should have burst open. To ensure all berries are open, mash the elderberry juice with a potato masher that has small holes.
Assemble a mesh sieve, funnel and liquid measuring cup to strain the elderberry juice. Once all the juice is strained, squeeze the berries to remove any remaining juices.
After squeezing the elderberries, you should have about ½ cup of elderberry juice. Pour all juice into your pint jar.
Let the juice cool to room temperature.
After cooling, add half a cup of each apple cider vinegar and raw honey. If using, add any desired optional spices like rosehips, cinnamon and ginger. Stir well and secure the air tight lid.
Store in the refrigerator for later use. For best results, use within 6 months – 1 year.
