Running hard water through your coffee equipment can lead to mineral buildup and calcification on your heating elements. If you’re looking to get the most out of your commercial coffee maker , then it’s important to make sure it’s properly cleaned. Cleaning your coffee maker will not only prolong its life span, but it will also improve the taste of your coffee. You should be cleaning and deliming your machine at least once every six months, however if the water you use is extremely hard, you may need to clean it every month. Follow our video and step-by-step instructions to get your coffee maker back in top shape, and don't forget to set up a water filtration system for your coffee equipment to cut down on mineral buildup in the future. Step-by-Step Instructions for How to Clean a Coffee Maker 1. Unplug the coffee maker. 2. Wipe down the machine with a damp towel. After you're finished wiping down your machine, you should plug it back in to begin the deliming process. 3. Mix 10 oz. of lemon juice with 32 oz. of water. 4. Pour the mixture into the water reservoir. 5. Turn your coffee machine on as if you are brewing a pot of coffee. 6. Once your coffee machine has finished its brewing cycle, remove the machine's spray head. 7. Remove any residue that may be blocking the holes on the spray head. 8. Insert a deliming spring into the opening where the spray head was. In a sawing motion, move the deliming spring back and forth about 5-6 times. Run two or three brewing cycles with plain water in order to remove any traces of lemon water solution. 9. Wash the coffee filter with warm, soapy water.
The monks thought the goat herder was a fool, and told him as much by throwing the beans in the fire. Sigh. Well, soon the enticing aroma of fresh roasted coffee was too much to ignore. The monks henceforth reversed their snubbing of coffee beans, scooped them out of the fire and threw them into some hot water. Then they drank the dark brew. Ta-da! The first cup of coffee! That was back in the year 850CE.

These organizations consider how long it takes you to brew the coffee, the social impact of the coffee maker, as well as the roasting ability of the coffee maker. The best coffee maker will be BPA free and certified. An SCAA certified coffee maker, for example, will be able to deliver water at optimum temperatures throughout the whole brewing process, without compromising the integrity of the coffee at any point.​

Conceptually, MistoBox splits the difference between many other coffee subscriptions—and it's our best coffee subscription box because of it. The company doesn't roast its own beans, but instead sources them from top roasters all across America, who ship the fresh-roasted coffee direct to your door. It doesn't ask you to participate in blind tastings, and it doesn't give you a detailed quiz up front. It's all about balance.
You might have heard that purchasing a double-boiler espresso machine or a proportional-integral-derivative (PID) controller will give you more accuracy and control over temperature. They’re definitely features to dig into for advanced espresso crafters, but expect to pay an additional $400 for a PID and $800+ for a second boiler. Since we wanted to focus on beginner machines, we stuck to single-boiler models without PID controllers for this review.

‡Pre-Infusing: Pre-infusing is a technique where the dry coffee grounds are initially saturated with hot water, allowing a “bloom” of carbon dioxide to escape. This 45-second(ish) process puts hot water into contact with more surface area around each ground throughout the brewing process, as it’s no longer competing with the escaping gas bubbles. It can improve the quality of the final product, since this more uniform contact creates a more even extraction. It’s a feature that six of the 10 pots we tested incorporated into their designs — as well as all four of our top picks.

The principle of a vacuum brewer was to heat water in a lower vessel until expansion forced the contents through a narrow tube into an upper vessel containing ground coffee. When the lower vessel was empty and sufficient brewing time had elapsed, the heat was removed and the resulting vacuum would draw the brewed coffee back through a strainer into the lower chamber, from which it could be decanted. The Bauhaus interpretation of this device can be seen in Gerhard Marcks' Sintrax coffee maker of 1925.
If you’re ready to drop serious money on a high-quality espresso machine that produces smooth, complex shots, our pick is the Rocket Espresso Appartamento Espresso Machine. The machine lets you cycle quickly between steaming milk and pulling espresso: It uses a heat exchanger, rather than the more typical thermoblock, which means that the Rocket’s boiler heats all the way up to milk-steaming temperatures when you first turn it on. When you’re ready to pull shots, the heat-exchanger sends a burst of cool water through a copper tube in the boiler, bringing the temperature briefly back to espresso-friendly levels before heating back up.
If all you’re looking for is a gorgeous cup of coffee and no fuss, we strongly recommend the Bonavita BV1900TS. It’s the smallest machine among our top picks and, at $190, the cheapest. Even better, it ranked in the top three out of 10 during our taste tests. It’s also the simplest and most straightforward: one button you click to start brewing, and that’s it. You can’t program brew times; you can’t play around with water temperature; and it even lacks some convenient touches like a brew basket that attaches to the machine (when you’re done brewing, you have to place the brew basket on a plate or in the sink before it makes a total mess). But it’s by far the fastest machine out of our top picks, brewing up a full eight-cup pot in under six minutes. It’s a straightforward, high-end coffee maker that leaves little to complain about.
With its mid-century design and an exposed reservoir, you'll want to leave the Moccamaster out on the counter even when it’s not in use. But it doesn't just look great. Indeed, the pricey Moccamaster brews a complex and smooth pot of coffee that ranked highest in our taste test. This machine also fills a full pot quickly—a necessity for the morning rush.

The Baratza Encore is simplicity defined and our top coffee grinder. This burr grinder has a 40-setting grind size selector, an on-off switch for continuous grinding, and a push-button for manual control. That's it. Other grinders include complicated timers, built-in scales, strength adjustment sliders, and other doodads, but Baratza suggests that you don't need them—and they're right. Measure your beans using a separate scale, grind them fresh for each cup. That's the way to do it.
A new French press is an ideal companion on a camping trip or picnic. Our sturdy versions of French presses are available in glass, metal, ceramic and other materials. Invest in your own efficient single-cup brewers with included cups and thermal mugs to create on-the-go coffee drinks for one person. Cold-brew machines and kits are other terrific options when you prefer chilled and iced coffee beverages. Remember to order plenty of filters, tampers, descaling tabs and other coffee accessories to keep your machine fresh and bright. Clean machines with the right size filters brew the best coffee
