Put the grated apple, dates, almonds, walnuts, and cinnamon in a food processor.
Pulse the mixture a few times until the nuts and dates are finely chopped, but not completely pureed.
Add the sweet red wine or grape juice and pulse the mixture a few more times until everything is well combined and the mixture has a slightly chunky texture.
Taste and adjust the seasoning as needed, adding more cinnamon for flavorfulness.
Transfer the Charoset to a serving dish and chill in the refrigerator until ready to serve.
