Coffee warmers are a personal choice. Do you nurse a single cup of coffee for hour after hour, or do you knock back cup after cup until morning is gone? Either way, there’s a warmer that will keep steaming hot coffee literally within an arm’s reach. Some rely on time-tested vacuum insulation technology, while others go the high-tech route with multiple electronic modes. Your first step towards choosing a coffee warmer is to decide how much coffee you want to keep warm in the first place.

Most countertop coffee makers shut off after a few hours, but if you need to keep your eyes open and stay sharp hour after hour, look for a coffee warmer built for the long haul. Maintaining heat in a large-volume warmer takes top-notch materials, so look for stainless-steel carafes that are easy to clean. A tight-fitting lid with a mechanical spout that allows pouring without removing the lid is a big bonus, too.

Coffee that sits too long on a hot surface will definitely take on a burnt taste, and burned coffee is heartburn waiting to happen. Some desktop warmers allow you to set a variety of minimum temperature ranges, while others have single settings. If you’re going to share a coffee warmer with someone else who prefers a different temperature, make sure to buy one of the variable models.

For many folks, simple is better: Who wants to stress out about settings and choices when it comes to a cup of coffee? Just keep the java warm, please, and don’t ask too many questions. A smart coffee warmer can do it all by itself: Keep the coffee at a just-right temperature. Know when to turn on the heat. And have a totally waterproof design so you don’t have to worry about spills. Some models even come with a gravity switch that cuts on each time you place a mug on the warmer.
