It’s obvious, but easy to forget: If you don’t clean out your coffee machine’s carafe after each use with soap and water, you’ll always end up tasting a little bit of yesterday’s now-bitter brew. Thermal carafes need to be hand-washed, but all the plastic components of our top picks — brew baskets, lids, etc. — are dishwasher-safe if you keep them on the top rack.
A cafetiere (Coffee Plunger, French press in US English) requires coffee of a coarser grind than does a drip brew coffee filter, as finer grounds will seep through the press filter and into the coffee. Coffee is brewed by placing the coffee and water together, stirring it and leaving to brew for a few minutes, then pressing the plunger to trap the coffee grounds at the bottom of the beaker.
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.
†Programmable Brew Time: Conventional wisdom frowns at grinding beans early and programming a pot to brew later. The aromatic compounds in coffee beans start to oxidize as quickly as 15 minutes after grinding, which causes coffee to start losing aroma and flavor. But Michael Ebert, senior consultant at Firedancer Coffee Consultants, LLC, assured us that, given the trade-offs for convenience, “grinding the night before will still make a great coffee — just not as great as it could be.” Seven of the 10 pots we tested are programmable, including three of our top picks (all but the Bonavita).

CR’s take: If you’re an aficionado of fresh ground coffee, this Black+Decker is the brewer to buy. As the name suggests, the Mill & Brew goes that extra mile, grinding whole coffee beans just before brewing. As a result, the machine is capable of making a great pot of coffee. Made of plastic with stainless steel accents, this model is easy to use and to clean, earning a Very Good rating in our convenience tests. It allows you to adjust brew strength, and it’s programmable, so you can set it to grind and brew just before you wake up.
This Good Housekeeping Seal star features an all-black body, a 12-cup glass carafe, a reusable filter and a backlit LCD screen with digital touchpad controls. You can program the clock to automatically brew coffee in the morning. It'll make a hot pot very quickly, but drink up — the keep warm feature didn't keep the coffee as warm as other models in our tests.
“I purchased the machine for myself as a birthday present, and I’ve had it for about six weeks. We have a Pavoni espresso machine, which my husband loves for his espressos, but I think it’s a pain for making lattes: grinding the beans, tamping down the pod, ‘pulling’ the lever (which will be really hard if you tamp it too densely), steaming the milk, and then cleaning the steaming wand, not to mention what a pain it is to refill the water chamber (turn off, wait till pressure is gone, then you can refill). Why am I listing all of these steps? Because that’s what you don’t have to worry about with the Lattissima! Here are my steps now: Turn on the machine, get the milk container out of the fridge and plug it into the front, put an espresso capsule in the top, stick a mug under the spout, and push the Latte button. Done. You do need to clean the frother, which is just putting another cup under the spout, turn the milk to “clean” and let it clean, then you can remove the milk container and stick it in the fridge. I clean the milk container once a week, soaking all the pieces in a bowl of hot, soapy water for a few hours.”
