All coffee lovers know that there are stretches of the summer where the weather is too sweltering for hot coffee and it's time to turn to iced coffee. Hot coffee from even the best coffee maker that is allowed to slowly cool to room temperatures turns stale, bitter, and sour. The key is to cool the coffee as quickly as possible, ideally while brewing.
Known as Japanese-style iced coffee, this method of flash cooling helps to seal in all of the delicious flavors while avoiding the unpleasant bitter and sour notes that come from allowing the coffee to cool to room temperature over an extended time. Cold brew avoids this altogether by using cold water and a much longer brewing process.
The great thing about iced coffee is that you don't need any new fancy equipment. Whatever brewing method you use at home can be used to make iced coffee.

Whether you are using a Chemex, Hario V60, or Kalita Wave, making iced coffee with a pour-over device is simple. Fill your brewing vessel with ice, then use half as much hot water when brewing. As the hot coffee hits the ice, it will melt and dilute the coffee, creating a well-balanced brew.
With manual brewing like this, you can have control over every brewing variable, which means you can customize the coffee to perfectly suit your taste. It's also possible to brew in bigger batches with pour-over devices.

Even the best Keurig coffee maker doesn't allow for as much customization as some other options, but it can still be used to make iced coffee. Some of the new Keurigs have dedicated iced coffee settings. If you don't have that option, you can use the machine like normal, just put ice into the cup you are brewing into. The Keurig is a single-serve coffee maker, so if you're intending to make iced coffee for a group, the cold brew or pour-over methods will be better for a larger batch.
