The best Cold Brew Coffee: Our Picks

Guide: Questions you should ask yourself before buying Cold Brew Coffee

Since we know our caffeinated pick-me-up rather hot, brewing it with cold water seems unusual at first. After all, a normally cooled coffee tips over and usually tastes sour. Cold Brew Coffee, however, is a new kind of taste experience! In this article you will learn everything you need to know to prepare Cold Brew Coffee in the best possible way.

What is behind Cold Brew Coffee?

Cold brew coffee sounds like two possibilities at first: It can be iced coffee, which is first prepared "normally", cooled and often heavily sugared and served with ice. Or you can think of actual cold coffee that you have forgotten on your desk and that does not stimulate a great thirst. Cold Brew Coffee is neither of these - here the flavours are not extracted with hot water, which is quick and very common. However, some heat-sensitive flavourings can be lost in the process. However, if you infuse the coffee with cold water, it is a gentle preparation method. One might think that this is a novel method from the hippest cafés.

However, Dutch merchants knew the gentle preparation method with cold water and coarsely ground coffee. At that time, the reasons for this change in habits were not of a taste-aesthetic nature, but rather of a pragmatic nature. Above all, it was about overcoming the dependence on heat sources in a time before the industrial revolution and electricity. Now we can be very grateful to our Dutch friends, because Cold Brew Coffee has entered numerous coffees worldwide and delights countless coffee fans with its mild taste.

What are the main differences between Cold Brew Coffee and hot coffee?

The differences in preparation are not limited to the water temperature. They also stand out in the following aspects:

  • Preparation time
  • Taste
  • Ease of digestion
  • Shelf life

First we record the differences in a table, then we explain the individual factors in detail.

Detail Hot brewed coffee Cold Brew Coffee
Preparation time approx. 5-10 minutes Up to 24 hours
Taste Strong, contains bitter substances Mild-fruity, aromatic, hardly any bitter substances
Digestibility Can irritate the stomach and cause heartburn (due to the bitter substances) Well digestible due to the gentle preparation
Shelf life Until it has cooled down approx. 14 days

As Cold Brew Coffee is not really brewed but rather extracted, it can take up to 24 hours to prepare. Although the coffee is left to stand for a long time, it becomes neither bitter nor sour. This is because the Cold Brew Coffee does not come into contact with hot water and does not release bitter substances in the first place. In addition, Cold Brew Coffee is considered more digestible when compared to hot coffee.

This means that even people with a rather sensitive stomach can enjoy the perfect coffee!

The shelf life of Cold Brew Coffee is a particularly attractive advantage: it can be kept for around two weeks. You can simply prepare it in larger quantities for the coming days and consume it like a soft drink. It does not lose any of its flavour qualities because it is cold from the start. Hot brewed coffee, on the other hand, is usually too bitter after it has cooled down and is no longer enjoyable when warmed up.

What do I need to prepare Cold Brew Coffee?

The preparation process for Cold Brew Coffee can be made in different ways. You can approach the equipment in a correspondingly minimalist or professional way. Basically, you will need the following three things to prepare Cold Brew Coffee:

  • Coffee beans
  • A container (e.g. French Press or Cold Brew Maker)
  • Water
  • Spices (optional)

Which coffee beans can be used for Cold Brew Coffee?

In principle, you can use normal Arabica beans that are available in every supermarket. However, since the main aim of the Cold Brew method is to achieve the most aromatic results possible, you can experiment with the choice of beans. There is a very large selection of beans with which you can strongly influence the taste.

It is therefore important to use freshly ground coffee beans; pre-ground coffee can make the taste dull and weak. The right grind also plays an important role. The beans should be ground rather coarsely so that no "coffee slush" is produced in the French Press or Cold Brew Maker. You should still be able to clearly recognise individual grains!

Cold Brew Coffee - French Press or Cold Brew Maker?

Basically, you can simply prepare Cold Brew Coffee in a French Press. To make it, put the coarsely ground coffee beans into the French Press and add the cold water. Then stir the coffee grounds and allow the coffee to steep. You can put the French Press in the fridge for this, but it is also sufficient if it is simply left at room temperature. Some coffee experts add additional aromas to the coffee, such as cardamom or cinnamon. The Cold Brew Maker is a practical invention in that the coffee usually goes into an integrated filter or strainer. In this way, you end up with a drink without grains, so no additional filtering is necessary. In addition, it is often possible to add ice cubes to a special container together with water. Since the brewing process takes a long time (12-24 hours), the Cold Brew Maker can simply be left to stand. In this way, the preparation of Cold Brew Coffee becomes a matter of course.

Decision: Which types of Cold Brew Coffee Makers are there and which is the right one for you?

Basically, you can distinguish between four different types of cold brew coffee makers:

  • Full-Function Cold Brew Coffee Maker
  • Basic Cold Brew Coffee Maker
  • Cold Brew Coffee Maker with plastic inserts
  • Cold Brew Coffee Maker made of glass

Depending on the area of application, you can decide on one of these four categories. The following sections will help you make your decision.

What distinguishes a Full-Function Cold Brew Coffee Maker and what are its advantages and disadvantages?

This is a design that makes the preparation of Cold Brew Coffee child's play. Since it takes a long time to prepare Cold Brew Coffee, it makes sense to make it in larger quantities. The Full-Function Cold Brew Coffee Maker combines all the functions needed to prepare cold brew coffee using two different methods.

Advantages
  • Integrated ice chamber
  • Large container
  • Integrated coffee filter
  • Allows multiple preparation methods
Disadvantages
  • Elaborate construction
  • Not dishwasher safe

What are the features of a Basic Cold Brew Coffee Maker and what are its advantages and disadvantages?

The Basic Cold Brew Coffee Maker is a well-made and elegantly designed coffee maker. Its function is limited to the preparation of Cold Brew Coffee according to the Cold Brew method, but it offers a balanced and delicate taste experience.

Advantages
  • Simple construction
  • Few individual parts
  • Easy cleaning
  • Integrated coffee filter
Disadvantages
  • Only suitable for one preparation method

What distinguishes a Cold Brew Coffee Maker with plastic inserts and what are its advantages and disadvantages?

A Cold Brew Coffee Maker with plastic inserts is usually in the affordable price range. If you do not make Cold Brew Coffee too often and/or do not attach much importance to an elegant finish, this type of Cold Brew Coffee Maker may be suitable for you. They are usually dishwasher-safe and quite light, but at the same time sturdy.

Advantages
  • Easy to clean
  • Integrated coffee filter
  • Dishwasher safe
  • Sturdy construction
Disadvantages
  • Less elegant look
  • Less environmentally friendly material

What distinguishes a Cold Brew Coffee Maker made of glass and what are its advantages and disadvantages?

The Cold Brew Coffee Maker made of glass is often in the upper price range. Provided the workmanship is of high quality, such devices are sturdy and look very elegant. However, some glass cold brew coffee makers are not dishwasher safe and should only be washed manually.

Advantages
  • Simple assembly
  • Few individual parts
  • Integrated coffee filter
  • Elegant look
Disadvantages
  • Not always dishwasher safe
  • Higher risk of breakage

Buying criteria: These are the factors you can use to compare and evaluate Cold Brew Coffee Makers

In the following, we would like to show you which factors you can use to compare and evaluate Cold Brew Coffee Makers. This will make it easier for you to decide whether a particular cold brew coffee maker is suitable for you or not. In summary, these are:

  • Container volume
  • Cleaning
  • Number of parts
  • Processing material
  • Number of functions

Container volume

The volume is very important, as Cold Brew Coffee is usually prepared in stock. The long shelf life allows the refreshing drink to be prepared as a precaution. The volume usually starts at about 400 ml and can go up to one litre. Which size is more practical also depends on how the coffee is to be stored afterwards. If you want to put the Cold Brew Coffee directly in the coffee maker in the fridge, it should fit in terms of size. So if you have a smaller fridge, it may make more sense to opt for a smaller Cold Brew Coffee Maker.

Cleaning

Cleaning should be as easy as possible. Therefore, make sure that the Cold Brew Coffee Maker is dishwasher safe, for example. If this criterion is not important to you, the coffee filter should be easy to clean. Especially with filters that have a sieve structure, it can prove difficult to get the coffee out. However, there are also sturdy plastic filters that are much easier to clean.

Number of parts

If the Cold Brew Coffee Maker is made up of a lot of small individual parts, cleaning and general handling can become a fiddly job. You should therefore look at where you set your preferences: some Cold Brew Coffee Makers are constructed from many individual parts in order to be able to fulfil several functions. Others have a simple structure and are designed to simplify the preparation process. They are therefore usually easier to handle and less complex to use.

Processing material

The processing material of the Cold Brew Coffee Maker is decisive in different respects: Glass is recommended because it is environmentally friendly and tasteless. Plastic inserts are therefore more advisable on the outside processing, whereby the vessel itself should be made of glass.

The coffee filter should be able to hold the coarsely ground coffee well and be quite stable.

Number of functions

In the case of Cold Brew Coffee Makers, this criterion means the number of possible preparation methods. Since Cold Brew Coffee can be prepared in different ways, it may depend on the Cold Brew Coffee Maker how many of them you can try.

Trivia: Interesting facts about Cold Brew Coffee Makers

What exactly does Cold Brew Coffee mean?

"Brew" comes from English and means "to brew". This makes sense, because coffee is usually brewed with hot water. But brewing with cold water does not work, at least not conceptually, which is why in German it is more commonly referred to as "cold extraction".

Does Cold Brew Coffee contain caffeine?

Yes, and how! Due to the long extraction time, sometimes even more caffeine is extracted than is the case with hot-prepared coffee. You can create a fruity and individual taste by adding spices and virtually make your own energy drink with up to 50 mg of caffeine per 100 ml.

What else is Cold Brew Coffee good for?

Cold Brew Coffee is not only great for drinking on its own, but can also be mixed with other drinks. Of course, you can refine it in the classic way with milk, but it is also very tasty with alcoholic drinks.

How widespread is Cold Brew Coffee?

In Germany, just under 20% of all respondents drink Cold Brew Coffee regularly. In the USA, however, the trend has become part of everyday life: some pubs now even offer Cold Brew Coffee from the counter and tap it like beer.
