Other coffee brewing devices became popular throughout the nineteenth century, including various machines using the vacuum principle. The Napier Vacuum Machine, invented in 1840, was an early example of this type. While generally too complex for everyday use, vacuum devices were prized for producing a clear brew, and were popular up until the middle of the twentieth century.
Picking up a bag of coffee beans from the roaster is a great way to make sure you have fresh beans. Because coffee gets damaged as it’s exposed to air, espresso connoisseurs recommend using beans within two weeks of their roast date. But you won’t want to use them the same day that they’ve been roasted — they need a few days to de-gas from the roasting process.
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.
A good grinder: An even grind is essential for drinkable espresso. In fact, if you’re trying to save money, most experts recommend cheaping out on your espresso machine rather than your grinder. Since we wanted to make sure our machines had the best chance of making great espresso, we started with a $600 grinder recommended to us by Seattle Coffee Gear.
Made in Italy by a company that has been manufacturing coffee makers for over 80 years, this espresso maker takes less than five minutes to produce up to 3 demitasses (2 ounces) cups of espresso. It is made from polished aluminum in a classic octagon shape that will look good on your stove or table, while the shape also helps to diffuse heat perfectly. It has a patented safety valve for protection and is easy to disassemble for cleaning.
The single-serve or single-cup coffeemaker has gained popularity in recent years. Single-serve brewing systems let a certain amount of water heated at a precise temperature go through a coffee portion pack (or coffee pod), brewing a standardized cup of coffee into a recipient placed under the beverage outlet. A coffee portion pack has an air-tight seal to ensure product freshness. It contains a determined quantity of ground coffee and usually encloses an internal filter paper for optimal brewing results. The single-serve coffeemaker technology often allows the choice of cup size and brew strength, and delivers a cup of brewed coffee rapidly, usually at the touch of a button. Today, a variety of beverages are available for brewing with single-cup machines such as tea, hot chocolate and milk-based specialty beverages. Single-cup coffee machines are designed for both home and commercial use.
