If you've ever made cold brew coffee at home, you know that though it's an easy process, it takes a long time. Like, really long. But what if your craving for a refreshing glass of iced coffee wasn’t immediately dashed away by the realization that, if you wanted cold brew, you would’ve had to start making it at least 12 hours ago?

With the G-Presso, you’ll never have to feel that disappointment again. The innovative coffeemaker, available now on Kickstarter, uses a gyro-pressed extraction method to transform your water and coffee grounds into summer’s hottest cold drink in an impressive four minutes flat.

All you have to do is add coffee grounds (a fine grind will create a bold, intense flavor, while a medium grind will give you more mild coffee) and up to five cups of water. Then press the power button on top of the machine and watch the G-Presso work its magic.

Here’s how it does it: The porous container with the coffee grounds inside spins rapidly, while the water above filters through it. The pressure created by the centrifugal force releases the coffee’s full-body sweetness and flavor in a fraction of the time it would take for that process to happen on its own. Your coffee will also be topped with a rich crema, similar to what you see on top of an espresso shot (which you don’t normally get with regular cold brew).

You might think that such a fast-paced, energy-filled process would generate a lot of noise, but the developers at Camfron Co. wanted to make sure they didn’t ruin your tranquil summer mornings (or afternoons) with a buzzsaw-esque whirring, so they created a noise-blocking silicon pad for the G-Presso to sit on.

The G-Presso is powered by three AAA batteries, making it perfect for bringing to a friend’s house, on vacation, or anywhere else you might need a cool, caffeinated pick-me-up but don't have room for a full-on coffee machine. For cold weather or frigid apartments, you can certainly opt for hot coffee instead—just use boiling water.

But you don’t have to limit your choices to cold or hot coffee. The G-Presso comes with a milk whisk that magnetically connects to the detachable control stick from the water container, giving you the ability to froth your way to the latte of your dreams.

Prices for the G-Presso start at $64 (which includes one machine, one extra basket, and 90 grams of ground coffee) for August delivery. You can view additional buying options on Kickstarter.

Ninja’s Hot & Cold Brewed System Is the Only Coffee Maker You’ll Ever Need

Update: The glass-carafe version of the Ninja Hot & Cold Brewed System is currently on sale for $99 (a 50 percent discount) on Amazon and Walmart. That's the cheapest price we've ever seen, so grab it while you can. The thermal-carafe version is on sale on Amazon for $168, a 27 percent discount.

For people who just want a cup of joe to help them get out the door in the morning, the French presses, Chemexes, Aeropresses, Moka pots, and other specialized devices that coffee aficionados swear by probably seem more overwhelming than appealing. Ditto the fancy cappuccino machines at local cafes. That’s where Ninja’s new Hot & Cold Brewed System comes in: It was created to give coffee addicts a myriad of options with minimal fuss, not to mention minimal equipment. And it makes tea, too!

“Coffeehouses are known for having an endless selection, but current at-home brewers haven't given users the vast variety of choice we thought possible, and certainly not all in one product," Mark Rosenzweig, CEO of SharkNinja, said in a press release. "The Ninja Hot & Cold Brewed System changes the category entirely. This innovative system is more than just a machine you use in the morning; it's your all-day brewing partner.”

The Hot & Cold Brewed System comes with two baskets: one for coffee and one for tea. It knows what you're making to make based on the basket you insert, and the available options for that basket will light up. The machine allows the user to make six different sizes of coffee or tea, from a single cup all the way up to a full 50-ounce (10-cup) carafe.

And of course, as the name suggests, the system can make both hot and iced beverages. For coffee, it has five brew options: classic, rich, over ice, cold brew, and specialty (a concentrated brew for milky drinks like cappuccinos). If you’re making tea, you can choose between hot and cold brews optimized for herbal, black, oolong, white, or green tea.

When you select an over ice or cold brew, the machine automatically doubles the strength of your beverage so it doesn't get overly diluted by the ice cubes in the carafe. Even better, the Ninja can make cold brew in just 10 to 15 minutes, whereas other systems and methods typically take hours. (Hot coffee is brewed at 205°F, while the cold brew is made at 101°F.) And the system has a hot and cold frother that folds into the side so you can make barista-level lattes, too.

These bells and whistles sound impressive on paper, but how do they perform in real life? Ninja sent me Hot & Cold Brewed System to test for myself.

Ease of Use

Though it might look like something developed by NASA, the Hot & Cold Brewed System is designed to easily work with the twist of a dial and the push of a button, and it delivers. From loading in the correct amount of grounds with the system’s “smart scoop” to picking what type of brew you’d like, it’s simple enough to use even while bleary-eyed in the morning. It’s also easy to schedule a delayed brew so you can do the rest of your morning routine while your coffee brews. (Here’s the only drawback I can think of about this machine: When it starts brewing, it’s kind of noisy—loud enough to make my cats jump. It’s not a dealbreaker, but if you live in a small apartment and plan to brew coffee so that it’s ready right when you wake up, it might be something to consider.)

The system even tells you when it needs to be descaled. The “clean” button will light up, at which point you simply fill the water reservoir with descaling solution and water and press the clean button. A countdown lets you know how much longer the clean cycle will last.

Taste and Flavor

I swapped out an old, cheap coffee maker for the Hot & Cold Brewed System, and the difference was immediately noticeable. Whether hot or cold, the coffee made by the H&CBS was a better, smoother cup of joe. That’s due to what Ninja has dubbed Thermal Flavor Extraction automated brewing technology, which, according to a press release, “knows the precise temperatures, correct bloom times, and proper levels of saturation for every possible beverage combination to ensure a great taste every time.”

Whatever tech they use, it works. The coffee I make in this machine is consistently tasty. The rich brew setting works exactly as advertised, too, providing a richer, bolder flavor than the classic brew.

Features and Accessories

One of the best things about the H&CBS is the fact that it cuts down on waste significantly. Unlike other machines, it doesn't require any plastic pods or paper filters. Instead, it comes with two permanent filters, one for coffee and one for tea.

And the cold brew function is a game changer if you prefer iced coffee to hot. Not only does it brew quickly, but it eliminates the messy cleanup that comes with making cold brew yourself.

Typically priced at $230 for the thermal carafe version (or $200 for the glass carafe), the Hot & Cold Brewed System is significantly more expensive than a simpler drip coffee machine. But if you’re a cold brew addict looking to treat yourself, it’s worth it. Consider springing for the slightly more expensive thermal carafe model, which will keep your java hot or cold for hours. (I’ve left ice in it overnight and found cubes the next morning.)

You can get the Hot & Cold Brewed System on Amazon, Walmart, Macy's, or directly on Ninja’s website starting at $160.

Fuel Your Cold Brew Obsession With This Elegant, Efficient Coffee Maker

The sun is scorching, the days are endless, and the gentle clinking of ice cubes in a glass of cold brew coffee sounds like chimes at the gates of heaven itself.

A beverage so divine deserves to be created by a machine to match, right? Meet Brrrewer, a coffee maker that will provide you with the smoothest, sweetest, richest cold brew coffee you’ve ever had—and it’ll do it in just four hours.

Brrrewer uses the cold drip method to brew coffee in which coffee grounds are suspended between two microfilter membranes. Water is poured over the top membrane, then slowly filters through the coffee grounds and drips out from the bottom membrane. The top membrane ensures that the water is evenly distributed among the coffee grounds, and the bottom membrane allows only the water-turned-coffee to fall into the carafe below, without any of the gritty residue. (That gritty residue is often a result of the full immersion method, which is popular among those with French presses; basically, you just steep your coffee grounds in cold water for 12 to 24 hours, strain out the grounds, and drink.)

The carafe is encased in a second layer of glass, providing thermal insulation and keeping your coffee cold for longer than a regular glass bottle or pitcher. And you can cross “coffee filters” off your shopping list—the microfilter membranes do that job already.

The Italy-based team at Essense designed Brrrewer with elegance and minimalism in mind, so it won’t throw off the aesthetic groove of your kitchen. In fact, it might enhance it. Also, it’s manufactured from a combination of borosilicate glass and BPA-free Tritan plastic; in other words, it’s extra-sturdy and environmentally friendly.

Mixologist Francesco Corona, five-time Italian “Coffee in Good Spirits” champion and world championship finalist, worked with Essense to develop special cocktail recipes for Brrrewer, which you can find in the paperback book, available on its own for $17 or with Brrrewer (the book and coffee maker combo is $78). Order Brrrewer by itself for $67 here, or see other purchase options from Kickstarter.

If four hours is more than you’re willing to wait for cold brew, check out Ninja’s Hot & Cold Brewed System, which can make it in about 15 minutes.
