Iced coffee is a wonderful treat to have when it’s hot out. It satisfies both your need for a cold beverage, and your sweet tooth (should you be fond of adding sugar and milk). However, it is quite difficult to make a good iced coffee at home.
Should you be particularly fond of cold coffee, then the Yama Cold Brew Drip Tower may be an excellent investment. This is a way of making coffee in which you actually need to use ice during the brewing process to make your drink. Although, you will need to have some pretty awesome patience, as it takes about 5-8 hours to make 30 ounces of coffee. The benefit though, it having a very low acidity. One of these will set you back about $220. Unless you just really love this method for preparing iced coffee, it might be better to make your favorite drink another way.
Cold brewed coffee is great and has several benefits. Low acid is just one. The Yama is a neat item but at that price point you'd have to be a big time coffee connoisseur. If you are more into function vs. aesthetics then I'd highly recommend the Fridge Barista Cold Brewed Coffee Maker. It is affordable and it makes, stores & serves the cold brew extract.
I don’t buy this American imperative to control our body temperature through beverages. The rest of the world doesn’t need that.
