In the semi-automatic machine, water pressure and temperature must be stable and consistent, and according to our expert, the pressure shouldn't be too high. Typically, coffee is brewed at a pressure of about 10 bars, and an ideal water temperature is around 195 degrees. Generally, the more expensive the machine, the better the equipment inside that regulates these two factors. High-quality machines tend to have a mechanism called a PID, or proportional-integral-derivative, controller. The PID's function is to maintain constant water temperature with extreme accuracy, down to the degree. Two central problems plaguing inexpensive espresso machines is that they lack a PID, meaning the temperature of the brewing water can fluctuate up and down and yield inconsistent results. Inexpensive machines often advertise that they have 15 or 20 bars of pressure as a selling point. But, higher pressure is not the priority, and too much pressure can actually lead to over-extraction and bitterness in your espresso shot. Therefore, we looked for a machine with good temperature and pressure control.

"My absolute love of the Delonghi Maginfica ESAM3300 is hard to describe. It has been a faithful crema steeped friend and morning ritual for at least 8 years, and the current unit I bought as a replacement last week (another ESAM3300) is a testament to why I give this well built Italian Stallion "super automatic" espresso dream machine a SOLID 5 star rating.
Percolators began to be developed from the mid-nineteenth century. In the United States, James H. Mason of Massachusetts patented an early percolator design in 1865. An Illinois farmer named Hanson Goodrich is generally credited with patenting the modern percolator. Goodrich's patent was granted on August 16, 1889, and his patent description varies little from the stovetop percolators sold today. With the percolator design, water is heated in a boiling pot with a removable lid, until the heated water is forced through a metal tube into a brew basket containing coffee. The extracted liquid drains from the brew basket, where it drips back into the pot. This process is continually repeated during the brewing cycle until the liquid passing repeatedly through the grounds is sufficiently steeped. A clear sight chamber in the form of a transparent knob on the lid of the percolator enables the user to judge when the coffee has reached the proper color and strength.
Prior to the introduction of pre-measured self-contained ground coffee filter rings, fresh coffee grounds were measured out in scoopfuls and placed into the metal percolator basket. This process enabled small amounts of coffee grounds to leak into the fresh coffee. Additionally, the process left wet grounds in the percolator basket, which were very tedious to clean. The benefit of the Max Pax coffee filter rings was two-fold: First, because the amount of coffee contained in the rings was pre-measured, it negated the need to measure each scoop and then place it in the metal percolator basket. Second, the filter paper was strong enough to hold all the coffee grounds within the sealed paper. After use, the coffee filter ring could be easily removed from the basket and discarded. This saved the consumer from the tedious task of cleaning out the remaining wet coffee grounds from the percolator basket.
The OXO is SCAA-certified, so we knew going in that it would heat water to the right temperature range and let coffee brew for the right amount of time. But what really sold us on the OXO was how its scrolling dial made even that customizable. Assuming you want to bring the extraction down a touch for lighter, subtler coffee, you can lower the water temperature with a twist of the dial. Likewise, if you want a slightly more robust aroma from your brew, you can increase the water’s temp the same way.
CR’s take: Like the model above, the Cuisinart Burr Grind & Brew takes whole coffee beans and grinds them fresh for each pot. It features programming, brew-strength control, a water filter, a permanent coffee filter, and auto-shutoff. This model earns a great rating for carafe handling. The stainless steel finish and glass carafe certainly elevate the experience of using it. Cuisinart brewers also received an Excellent rating for owner satisfaction. But the performance and finish come at a premium—this machine costs significantly more than the Black+Decker Mill & Brew.
