Value Editorial

To help you pick the best dual coffee maker you must first take a look at all the features and specifications these machines offer. In this next section, we’ll be talking about how to select the perfect 2-way coffee maker that meets your requirements.

How to Select the Best Dual Coffee Maker

For you to pick the correct dual coffee maker, consider how many people you’d like to serve and what type of coffee you prefer. In this buying guide, we’ll talk about the types of coffee makers you can get and the importance of brew sizes & functionality.  

4 Types of Coffee Makers

1. Espresso Machine

An espresso machine pushes high pressured hot water through a container of compact roasted ground coffee beans. This results in rich dark coffee with a smooth crema on top. The brew is known as an espresso shot and you can combine it with milk to make lattes & Cappuccinos.

Espresso machines have different brew options to make various strengths of coffee. Some machines come with milk frothers too. If you want a milk frother then purchase an espresso machine that has one on the side of the device because this design ensures ease of use.

2. Peculator or Drip Machine

A coffee percolator or drip coffee maker requires you to fill a tank with water. The hot water system slowly drips through a basket filled with ground coffee beans and filters it. There’s a jug that captures the brewed coffee. You can use this machine to make decaf or regular coffee.

The advantage of a coffee percolator is that it produces large quantities of strong brews that you can serve eight to 12 people with. It also produces piping hot coffee for people that don’t like lukewarm beverages.

3. K Cup Machine

A K Cup machine is a single-serve coffee maker. Coffee is stored in a small pod that’s placed in a capsule holder in the machine. There’s a reservoir that heats up water before pushing it through the single-serve pod and releasing it into a mug. These machines work fast and can brew great coffee flavors within 5 to 7 minutes.

4. Dual Coffee Maker

As mentioned before the dual coffee maker gives you the best of both worlds because it makes two types of brews. There are dual makers that have single-serve option on the one side and espresso or percolator on the other side.

A dual brew coffee maker is durable and easy to maintain. These machines are designed with coffee lovers in mind because they can make various types of brews. The brewing process on these machines is easier than other types of coffee makers.

Serving Size

When shopping for a dual coffee maker consider the size of the pot or the capacity of the water reservoir on the single-serve side. Most dual brewers on the market make between 11 and 12 cups of coffee.

So if you don’t enjoy filling up water reservoirs every time you want to make coffee, select a machine that has a tank with a large capacity.

Size of the Entire Machine

When searching for the best dual coffee maker, take a look at the size of the machine. Will it take up a lot of counter space or is it small enough to fit perfectly onto a small table?

There are many 2 way makers that are compact and offer multiple size options. Therefore it’s advised that you look at the dimensions of the dual brew machine before you buy it to ensure that it won’t take up precious counter space. Your dual brewer will fit perfectly in a coffee bar or small kitchen.

Features of a Dual Coffee Maker

Most popular dual makers are digital and you can program them to make hot & iced coffee brews. Use the settings to program the machine to make your coffee at a certain time of day such as in the mornings. This way you can wake up with a freshly brewed cup of joe ready, to enjoy with your breakfast.

Another feature you should look at is the digital display of the machine. These displays must be of the highest quality and it must allow you to adjust settings easily. Furthermore, the digital display gives you multiple coffee options such as adjusting the strength of your brew.

Drip Tray

A drip tray captures the spillage of coffee so that it doesn’t spill onto your counter or into the bottom of the machine. Select a dual maker that has a removable drip tray so it can be cleaned easily.

Type of Carafe

There are two types of carafes: thermal and glass. So what’s the difference between the two carafes? A glass carafe is see-through so you can see what the brew looks like in the coffee pot. Many people prefer glass carafes because they say the glass improves the taste of the coffee. The only downside to this type of carafe is it doesn’t retain heat.

Heating plates are necessary to keep the coffee hot inside glass carafes.

However, there are coffee enthusiasts that don’t like using a warming plate because it could potentially burn the brew. If this is your point of view, pour your brew into a thermal travel mug to retain its heat. To solve the problem, many people prefer thermal carafes because it retains the heat of the coffee for longer without the use of hot plates.

A 2-way maker with a thermal carafe is more expensive but to spend a bit more to retain the heat of your coffee is definitely worth it.

Maintenance of a Two Way Coffee Maker

You don’t want to purchase a two-way coffee maker that is a hassle to keep clean. Therefore, it’s important to select a machine that has removable parts that are easy to wash out and reassemble. Simply use warm water to rinse the removable components and wait for them to dry before placing them back into the machine.

If you want to clean them in a dishwasher make sure the parts are dishwasher safe.
