Pierce's design was later improved by U.S. appliance engineers Ivar Jepson, Ludvik Koci, and Eric Bylund of Sunbeam in the late 1930s. They altered the heating chamber and eliminated the recessed well which was hard to clean. They also made several improvements to the filtering mechanism. Their improved design of plated metals, styled by industrial designer Alfonso Iannelli, became the famous Sunbeam Coffeemaster line of automated vacuum coffee makers (Models C-20, C-30, C40, and C-50). The Coffeemaster vacuum brewer was sold in large numbers in the United States during the years immediately following World War I.
Tamp: To ensure the espresso is evenly packed, your machine comes with a tamp, which you’ll press into the basket against the grounds. This step is important: When you pull a shot, the water will go to the place of least resistance, avoiding densely packed areas. This denser espresso won’t be properly saturated, making it under-extracted and sour, while the looser espresso will be over-extracted and bitter.
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.
It can take a little while to get to know the ins and outs of a new coffee maker. In CR’s labs, each drip coffee maker we test brews roughly 65 cups by the time our engineers are through with it. And brewing is just one of many aspects we look at. We test for handling and convenience, too, so you can choose a model that helps you sail through morning madness.
