Bunn-O-Matic came out with a different drip-brew machine. In this type of coffeemaker, the machine uses a holding tank or boiler pre-filled with water. When the machine is turned on, all of the water in the holding tank is brought to near boiling point (approximately 200–207 °F or 93–97 °C) using a thermostatically-controlled heating element. When water is poured into a top-mounted tray, it descends into a funnel and tube which delivers the cold water to the bottom of the boiler. The less-dense hot water in the boiler is displaced out of the tank and into a tube leading to the spray head, where it drips into a brew basket containing the ground coffee. The pourover, water displacement method of coffeemaking tends to produce brewed coffee at a much faster rate than standard drip designs. Its primary disadvantage is increased electricity consumption in order to preheat the water in the boiler. Additionally, the water displacement method is most efficient when used to brew coffee at the machine's maximum or near-maximum capacity, as typically found in restaurant or office usage. In 1963, Bunn introduced the first automatic coffee brewer, which connected to a waterline for an automatic water feed.
For hundreds of years, making a cup of coffee was a simple process. Roasted and ground coffee beans were placed in a pot or pan, to which hot water was added, followed by attachment of a lid to commence the infusion process. Pots were designed specifically for brewing coffee, all with the purpose of trying to trap the coffee grounds before the coffee is poured. Typical designs feature a pot with a flat expanded bottom to catch sinking grounds and a sharp pour spout that traps the floating grinds. Other designs feature a wide bulge in the middle of the pot to catch grounds when coffee is poured.
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.
Finally, the design and extra tools that the Breville machine comes with are impeccable. It includes a large drip tray to catch spilled coffee and milk and has a sensor that lets you know when the tray is too full. It also has a compartment under the drip tray that allows you to store the extra filters the machine comes with. It includes a hefty, stainless steel milk steaming jug and a tamper for pressing the expresso grounds down. Other machines' tampers are made of flimsy plastic that left loose grounds around the sides of the portafilter, but the Breville tamper is made of thick, durable plastic and metal. It's strong enough to actually work well at compacting the grounds, plus it's perfectly sized to fit the entire circumference of the portafilter, reaching all of the grounds and not leaving loose stragglers. There's also a magnetic slot on the machine where you can house the tamper. It can be used while it's attached to the top of the machine, or taken down for more leverage—this is an impressive extra design feature, since the many parts required in making espresso can make for clutter.
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.
What Amazon users have to say: As you may expect, there are rave reviews for Nespresso. Users love the ease of making quality espresso with little to no effort or cleanup. The machine is energy and space-saving, and comes with top notch customer service should you need it. Amazon user LT was especially feelin' it, saying "If I could marry an appliance (is it legal?) I would spend the rest of my life with this espresso machine." We'll be sure to look into those marriage laws. In the meantime, here's more Inissia praise:
“My boyfriend is a gadget nerd, and he bought the Bonavita 1900TS drip for us — it’s turned out to be pretty great. We had been using Chemex, but it’s hard to be patient in the morning! If you take the time you’d spend waiting for a pour-over and actually weigh the beans, then this baby is unbeatable. It tastes almost the same as the Chemex.” — Sara Conklin, owner, Glasserie

Espresso shots need to be pulled between 186 and 194 degrees F. If the water is too cold when it hits the espresso, the shot tastes sour. Too hot, and it tastes burnt. It’s trickier to hit this window if you also want your machine to steam milk, since steam requires a higher temperature — at least 212 degrees. But we struggled to get several of our machines just to pull decent espresso, never mind the milk. Sour shots were a clear sign that the water wasn’t hot enough; scorched shots indicated that the water climbed over 200 degrees.
