The OXO Cold Brew Coffee Maker has a well-designed perforated lid that distributes water evenly and allows fresh coffee to bloom. Allowing your coffee to bloom for half a minute, depending on how fresh the roast is, will improve its flavor.
This cold brew coffee maker has no measurement markings, so it can be tricky to get the proportions right. If you use too much water and too little coffee, the brew will be too weak. If you have too much coffee and too little water, some of the coffee will get wasted because no water will reach it.
