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.
The Gaggia Classic is a stylish old-school Italian espresso maker. It can pull a really delicious, creamy shot of espresso, but the machine does not have a PID—therefore its results aren't very consistent. While the machine is pretty, it doesn't have the well-thought design features of the Breville, like a sensor drip tray and a space for the tamper, nor does it come with a milk pitcher. Its plastic tamper is flimsy and won't effectively press down the espresso grounds. The Gaggia's steamer wand also doesn't consistently incorporate foam, and instead produces large bubbles on top.
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
