In recent years air-pump-driven espresso machines have emerged. These machines use compressed air to force the hot water through the coffee grounds. The hot water is typically added from a kettle or a thermo flask. The compressed air comes from either a hand-pump, N2 or CO2 cartridges or an electric compressor. One of the advantages of the air-pump-driven machines is that they are much smaller and lighter than electric machines. They are often handheld and portable. The first air-pump-driven machine was the AeroPress, which was invented by Alan Adler, an American inventor, and introduced in 2005. Handpresso Wild, invented by Nielsen Innovation SARL, a French innovation house, was introduced in 2007.
Making the perfect espresso can be a labor of love, but not everyone who wants to drink espresso wants to do all that labor. Pod-based machines make it easier, but then you have fewer type of coffee to choose from. This machine solves both of those problems since it has adapters for most of the popular pods, including Nespresso, Dolce Gusto, K-Fee, or Verismo by Starbucks, and you can also use your own fresh ground coffee.
A steam-driven unit operates by forcing water through the coffee by using steam or steam pressure. The first espresso machines were steam types, produced when a common boiler was piped to four group heads so that multiple types of coffee could be made at the same time. This design is still used today in lower-cost consumer machines, as it does not need to contain moving parts. Also, steam-driven machines do not produce as high of a pressure for extraction compared to pump-driven. This results in the crema, a hallmark of an espresso, being of lower quality.
“What I REALLY like about it is that it’s pretty much an all-in-one system without the thousand-dollar-plus all-in-one cost. I push one button and all the magic happens, and it’s quite entertaining to watch the espresso cascade through the milk and create separate layers. I also like that I can take the milk and store it in my fridge. I’ve done some temperature tests, and only noticed a five-degree increase after making a double latte, before I put it back in the fridge. This is nice, as you would think that to be so close to all that heat, it would be a much bigger temperature fluctuation.”
Semi-automatic espresso machines are just that—semi-automatic. Some of the steps are automated, but many are not. This allows the user to put their personal stamp on the final product but without doing some of the tedious steps that are involved in making an espresso on the stove top. Here’s a look at some of the features that make a semi-automatic espresso machine such a great pickup for the ultimate espresso lover:
Now you can make authentic espressos, lattes and cappuccinos to suit your taste, in the comfort of your kitchen. Whatever your preference — single or double espresso, cappuccino or latte — the manual espresso machine brews authentic barista-quality beverages just like you enjoy at your favorite coffeehouse. With a manual espresso machine, you are guaranteed a true crema that’s rich, creamy, and full of flavor. Water and steam are heated separately thanks to the dual thermostat system, allowing crema to reach the ultimate consistency without scalding the coffee. For milk-based beverages, the manual frother mixes steam and milk to create a rich, creamy froth for evenly textured drinks — just the way you like them. Our patented three-in-one filter holders give you total control over your beverages and allow you to choose from one shot, two shot, or convenient espresso pods. The built-in tamper provides great flavor without the guesswork, and while the cappuccino systems may vary in method (one-touch automation for a semi-automatic model, versus an advanced manual frother for a traditional pump espresso machine), the results are consistently excellent. Don't like the idea of coffee grounds spilling everywhere, but still love the taste of fresh coffee? If you want all the convenience of an attached milk steamer and espresso maker, but less of the mess, we recommend the Nespresso range, with its convenient espresso pods, just as versatile as any of our other coffee machines. At De’Longhi, we’re proud of our manual espresso machines, and we hope you’ll be as enchanted by them as we are. Choose from a range of sleek, stylish designs, in black, red or stainless steel. Our machines are easy to use, easy to clean and easy to fill — exactly how they’re supposed to be.
