Combine spiced apple cider and frozen Oregon berries in the crockpot and heat on high for one hour. Strain hot cider through a fine mesh sieve and add strained cider back to the crockpot.
Keep berry cider on warm or low setting (depending on how hot you want it). Top with whipped cream and cinnamon to serve.
Notes
To make a spiked hot berry cider, serve along with your favorite spiced rum or vodka!
