Which types of coffee capsules are the most popular?

Coffee capsules are by far one of the most popular coffee products available. According to Straits Research, the value of the global coffee capsule and pod market is expected to reach US $50 billion by the end of the decade. 

Since the launch of Nespresso in the European market in the late 1980s, the consumption of capsules has continued to grow. Research from Statista estimates that single-serve brewing systems, such as Keurig, were the second-most popular brewing systems in US households in 2020 – and it’s likely this number has increased in the two years since.

Alongside consumption growth, the capsule market has also diversified, with more products available than ever before. In line with this, it’s important that roasters understand the differences between these products, as well as how popular they are in different markets, if they are to sell them successfully.

To understand more about how roasters can capitalise on different types of coffee capsules, I spoke with two industry experts at AFPAK, a capsule filling and packaging solutions company. Read on to learn more.

A brief history of coffee capsules

Today, there are many different types of coffee capsules and pods available on the market. However, this wasn’t always the case.

The invention of coffee pods can be traced back to Nestlé engineer Eric Favre when he visited the popular Italian espresso bar Caffè Sant’Eustachio in 1975. Upon seeing how baristas pulled the levers on espresso machines to extract espresso, he sought to create a more simplified version that mimicked the dynamics of these machines.

Over the next ten years, Favre developed a machine which used pressurised air and water to extract coffee. This resulted in an espresso-style drink with a more prominent layer of crema. 

In 1986, Nestlé registered a trademark and patented the machine, and in turn launched the Nespresso brand. The company initially targeted offices and workplaces, but found that there was little interest from buyers. 

However, in 1988, Jean-Paul Gaillard joined the company, and rebranded Nespresso as a “luxury” product range. As part of this, the price of each capsule increased by 50%, and customers automatically joined “Club Nespresso” after purchasing capsules – a marketing strategy which made Nespresso consumers feel like they were part of an exclusive coffee lifestyle brand.

Throughout the 1990s, Nespresso sales began to increase, but mostly in the European market. However, it was during this decade that competitor brands started to emerge. Green Mountain Coffee Roasters (now known as Keurig Dr Pepper) founded Keurig, a single-serve capsule brand, which became popular in the US. The company sells K-Cups, which are shaped differently to Nespresso capsules, but extract coffee in a very similar way.

Since then, the market has grown. Today, it’s estimated that there are more than 400 brands of coffee capsules and pods available on the market.

Why are coffee capsules so popular?

Jeffree Yang is the CEO of AFPAK. He explains that there are five factors driving the growth of the coffee capsule market: convenience, ease of use, affordability, product diversity, and an increasing focus on improving sustainability. 

He adds that preserving coffee freshness in capsules and pods is also another factor.

“The coffee is filled and packaged in airtight, sealed capsules to ensure that its flavours and aromas don’t degrade over time,” he tells me. 

Alongside the growing focus on preserving freshness as much as possible, there has also been an increase in the range of specialty coffee capsules on the market. In turn, this means capsule consumers are able to enjoy higher-quality coffee.

“Now more than ever, there is a wide variety of different capsules to choose from, which means roasters can cater to different taste preferences,” Jeffree explains.

Sustainability, meanwhile, has been a prominent topic of discussion since capsules entered the market decades ago. It’s believed that around 39,000 capsules are manufactured every minute around the world, prompting many consumers to express concerns about capsule waste.

Allen Cao is the Machine Designer at AFPAK.

“With the increasingly diverse range of more environmentally-friendly materials, coffee capsules can be made more sustainably,” he explains. As part of this, more roasters and capsule manufacturers are using recyclable materials, such as aluminium, as well as biodegradable and compostable materials. 

Which coffee pods are the most popular?

Out of all the coffee capsule brands available on the market, Nespresso still remains the most popular by far. It’s estimated that a staggering 400 Nespresso capsules are consumed every second around the world.

“Since their invention in the 1980s, a number of different types of Nespresso capsule have emerged, including those which feature different coffee origins and beverage styles,” Allen says.

It’s important to note that Nespresso remains very popular in Europe. However, in other international markets, there are a number of other prominent brands. To combat this, Allen tells me that Nespresso developed their Vertuo capsules specifically for the North American market, as they produce slightly larger beverages than the brand’s other capsules.

However, Jeffree tells me that Keurig is also popular in the United States. According to Statista, sales of Keurig Green Mountain pods totalled over US $1.2 billion in 2022. 

Both Jeffree and Allen explain that as well as Nespresso, there are several key coffee pod brands in the European market.

Italian brand Lavazza is well-known for its roast & ground products, but it also sells coffee capsules.

“Lavazza has a unique influence on Italian coffee culture,” Jeffree says.

Caffitaly is another major capsule brand, particularly in Germany. Allen tells me its capsule brewing systems were developed by Italian coffee machine manufacturer Gaggia, so they can more closely mimic espresso in the beverage style.

Capsule design & its impact on coffee extraction and flavour

Across the wide range of capsules on the market, there is a significant amount of variation in terms of size and design. Some brands have more coffee per capsule than others, for instance.

Both Allen and Jeffree agree that capsule design has a significant impact on extraction and flavour of coffee.

“In previous years, lower-quality capsule technology led to a number of issues in the brewing process, such as leaks, inconsistent flavours, poor extraction, and increased waste,” Jeffree says.

However, as technology has advanced, capsule design has changed and improved in recent years.

“This resulted in more innovation and development, not only to improve the brewing process, but also to maintain coffee quality and flavour,” Allen explains.

Jeffree explains more about Caffitaly’s capsule design.

“They include two micro-filter counter-pressures in the upper and lower parts of each capsule,” he says. “When the high pressure from the pump in the brewing machine (around 15bar) enters the capsule, the ground coffee is extracted through the top micro-pressure filter first so that the pressure is more evenly distributed.

“Once the coffee extracts through the second micro-filter, the pressure reverses, which results in a more intense flavour, as well as producing more crema,” he adds.

As well as Caffitaly, Allen tells me how Nespresso’s extraction technology works.

“It has two distinctive features,” he explains. “Firstly, coffee is extracted using centrifugal force generated by the high-speed rotation of the capsule.

“Secondly, as a result of the addition of air to the coffee and water, the crema becomes more pronounced,” he adds.

How are different types of capsules manufactured?

Given the sheer number of differences in terms of size and appearance, it’s understandable that companies manufacture capsules in a range of different ways. 

For roasters interested in selling capsules or pods, it’s important to understand these differences in order for them to get the best results.

“The type of capsule required is dependent on its structure, the amount of coffee, the amount of pressure used by the brewing system, flavours of the coffee, and more,” Allen explains.

Capsule materials is one of the most important factors to consider, as the material used is responsible for preserving coffee freshness and flavour. 

Allen recommends using aluminium for maximum freshness preservation.

“Aluminium creates a better barrier to oxygen, which can guarantee the freshness of coffee for a longer period of time,” he says. Moreover, aluminium is infinitely recyclable – as long as it is disposed of correctly.

“The emergence of more sustainable materials has led to many new opportunities for plastic capsules,” Allen explains. “Because of the increasing diversity of filling and packaging technology, more and more coffee companies can preserve the unique flavours in their coffee.”

He adds that for roasters and other coffee companies looking to sell capsules, working with capsule manufacturers like AFPAK can help to determine what the best options are for them – ensuring they stay on brand, as well as remaining profitable.

What should roasters consider when entering the capsule market?

Jeffree says that the first – and easiest – step to create your own coffee capsule is to choose a coffee.

“Every coffee has its own unique flavour profile, so you first need to select the right type of coffee,” he explains. “This includes different origins, altitudes, and terroir.”

The next step is choosing which brand of capsule is best suited to your coffee business.

“Certain capsule brands are more popular in different markets, so it is crucial that you choose the right brand for your target market,” Allen says.

Finally, one of the last steps is deciding how you want to fill your coffee capsules.

Jeffree explains that a high-quality capsule filling and packaging machine needs to do three things: high-precision filling, sealing, and nitrogen flushing.

“High-precision filling is necessary to minimise waste, but also to ensure that each customer receives capsules filled with the right amount of coffee,” he adds.

Flushing capsules and pods with nitrogen during the sealing process ensures that as much of the coffee’s freshness is preserved as possible.

However, in order to manufacture, fill, and seal capsules correctly, most roasters work with a specialist capsule partner.

“AFPAK has helped more than 300 coffee companies successfully produce coffee capsules,” Allen explains.

The coffee capsule market has come a long way since the 1980s, and there’s no doubt that it will continue to grow in the coming years. 

And as the market continues to develop, we should expect to see the number of different capsule types and models increase.

However, while creating your own coffee capsule range can be profitable, it can also be a difficult undertaking for small and medium sized roasters. As such, it’s important to consider working with external partners – allowing you to lean on their expertise throughout the process.
