The KitchenAid  Cold Brew coffee maker is so easy to use, and the results are gourmet! It is just 3 parts, the glass maker/decanter, the stainless steel steeper and lid.  You put the grounds in the steeper (which can also be used for tea!!!) pour water and brew! I let mine brew for 24 hrs, but it says anywhere from 12-24 hrs. I wanted it real strong, it came out perfect! Having brewed it for that long, i was extremely impressed with how smooth the brew was, and it was not bitter or acidic.  Also, the design & quality of the brewer is wonderful. It has nice gripping feet on it so it does not slide in the fridge. The holes/mesh on the steeper are so fine, no grounds got through into the brew! The stainless steel tap rotates easily on/off. No dripping. It exceeded my expectations. And if you love coffee, I am sure you will love this!
