@CoffeeJunky In fridge? As in leaving the cold brew in the fridge? That's how I always do mine. I make what are essentially large teabags out of coffee filters and let them float in a jar of water in the fridge for 24 hours. Although I feel that using lose grounds in the water gives better results, I haven't found an effective way to filter the brew that way.
@eldub I'd be doing the cold brew in milk for personal enjoyment. I'm wondering if anyone has tried it before and the results they had.
I made 2 cups of milk cold brew at a 1:6 ratio for 26 hours. It has a really smooth taste at the start and ends in a strong coffee flavor. I don't think it is worth doing again, but I would encourage that everyone tries it once. The coffee extracted just fine, but I did notice a layer of froth on top of the cold brew after I stirred the grounds in, which stayed for the entire time until I poured into a glass.
