Our recipe calls for around an eight to one ratio of water to coffee, which we think will taste delicious over ice; taking into account that the ice will melt, diluting the cold brew. However, it couldn’t be easier to adjust the recipe and brew a stronger coffee concentrate. You could use the same amount of water but two Trade Cold Brew Bags worth of coffee, for a concentrate that’s roughly twice as strong. The main advantage of making a concentrate is that it takes up less space, making it easier to transport. On the flip side, if our cold brew recipe is too intense for you, feel free to use less coffee for a more diluted brew. Just measure how much less coffee you’re using so you can repeat or accurately adjust it from batch to batch.
As long as you have a vessel that’s big enough to hold the Cold Brew Bag and narrow enough to submerge it all the way under the water, you’re golden. You can get away with a large french press, Tupperware container, or even a mixing bowl.In coffee shops, steeping big batches of cold brew coffee in a food grade bucket is very common. Whatever vessel you choose, just make sure to cover your container in some way to avoid contact with oxygen, which can interact with coffee and cause some slightly off flavors.
