Keurig and Nespresso manufacture brewing systems that make single servings of gourmet and premium coffees. Keurig machines use coffee pods, known as K-Cups, to brew their beverages and have connections to well-known beverage brands, such as Folgers, Celestial Seasonings, and Starbucks. Nespresso uses specially-perforated foil and plastic capsules for their machines, which only brew coffee, espresso, and cappuccino, though off-brand solutions for tea and hot chocolate do exist.

Whichever machine one chooses, the user is mostly locked into that company's marketplace, as the systems use proprietary technology that each company guards zealously. For instance, Keurig's K-Cups cannot be used to replace Nespresso capsules and vice versa.

Mechanism Keurig machines use a "K-cup," which has coffee and (sometimes) a creamer inside it, and brews partially according to user input. An aluminum capsule with partially-punched holes is pierced by the machine's brewing system. The hole patterns allow for different pressure and flow gradients.
Can brew Coffee, tea, hot chocolate Coffee, espresso, and (in some models) cappuccino Decaffeinato (Decaffeinated Coffee Pods are also available)
Brands Some common K-cup brands include Green Mountain, Caribou, Donut Shop, Tully's, Twinings, Folgers, Celestial Seasonings, and Starbucks. Brazilian Dulsao, Ethiopian Bukeela, Colombian Rosabaya, Indian Indriya, Hawaiian Kona and Maragogype Special Reserves.

Like Tassimo, Nespresso and Keurig machines focus on single-servings (one cup) of coffee. Where they differ is in that the Keurig can also make tea, hot chocolate, and other hot drinks, while the Nespresso only brews coffee, espresso, and cappuccino (in models with milk systems). Keurigs cannot brew espresso. Off-brand solutions exist for making hot chocolate and tea in a Nespresso machine, but these are not necessarily supported by the manufacturer and may void warranties.[1]

Brewing times will vary according to the model and the drink being made, but most preparations usually take fewer than 4 minutes, from start to finish. To brew coffee, the machines combine distilled water, heated to an exact temperature for the best flavor. Keurigs use pressure-based systems, while newer Nespresso models use a centrifuge-based technology for their brewing. Some Keurig and Nespresso machines carry their brewing tasks out better than others, meaning it is important to read reviews before purchasing a machine. For example, in the video below, which compares a Keurig coffeemaker to a Nespresso Vertuoline, the Keurig brews at a hotter temperature than the Nespresso.

Capsules vs. K-Cups

Nespresso developed their capsule-based brewing system in 1976, but it wasn't until 1990 that it began to catch on in European markets. The Nespresso capsule is made mainly from aluminum and uses a food-grade lacquer inside to further protect drink ingredients. The foil is slightly perforated in different patterns depending on the requirements of the particular coffee; these patterns adjust brewing times and temperatures, as needed. Keurig cups, called K-cups, are mainly made of plastic with a foil cover. A pod or capsule has only 3-4 grams for coffee (for example), enough for one cup.

The pod/capsule system keeps coffee fresh for a longer period of time, as it doesn't expose the grounds and other contents to air and humidity, as might happen with coffee in an opened bag or can.

Coffee Brands

Keurig offers over 200 kinds of drinks, including some made by the most familiar coffee and tea brands on the market. Among them are Green Mountain, Starbucks, Folgers, Twinings, Celestial Seasonings, Caribou, and Tully's.

Nespresso offers a wide range of coffees from around the world, including Brazilian Dulsao, Ethiopian Bukeela, Colombian Rosabaya and Indian Indriya, among others. Their focus on coffee also includes lungo coffee (for longer brewing times), vanilla-enhanced grounds, caramel-infused brews, spiced coffees, and limited edition grounds offered seasonally or annually. Examples of these limited editions include Hawaiian Kona Special Reserve and Maragogype Special Reserve.

A major difference between Keurig and Nespresso is that Nespresso does not have any deals with tea companies, so tea lovers may prefer Keurig machines for this reason alone. However, Nespresso owners have found creative workarounds to this problem.

Both companies use proprietary technology for their coffee pods and have often employed legal action to stop competitors from releasing similar, compatible, and cheaper products.


Nespresso and Keurig machines range from around $80-$100 to as much as $180-$300 for higher-end models. Nearly all models are for single servings, meaning they are best suited for homes and small businesses, where volume coffee-making is not required.

For a coffee drinker, each cup of Nespresso or Keurig brew will cost about $0.75 cents, with the more expensive grounds running as high as $2.00 per cup. Bulk buying of pods or capsules can bring this price down, but it stills cost several times more per cup than store-bought coffee brews.

Cost Per Serving

The coffee machines are a negligible part of the overall cost of enjoying Nespresso or Keurig coffee and drinks. Both companies sell their machines at close to cost with the idea of locking the customer in to repeat purchases of materials. The coffee in K-cups and Nespresso capsules costs several times more than store-bought grounds, with some grounds pricing out at the equivalent of over $50 a pound.[2]

Both companies have fought hard to keep competitors from releasing compatible, off-brand pods/capsules. Nespresso's patents expired in 2012 and their parent company, Nestlé, is trying to create new patents to extend protection. Keurig has fought against several companies creating generic pods, with spotty success. Both companies have explored licensing their technologies, mainly for the coffeemakers themselves.


As with all coffee machines, periodic cleaning is needed to preserve the purity of flavors in the brewing process. Some higher-end Nespresso models have an automated cleaning system, but most models from both companies rely on "blank brew" cleaning, the practice of running water and a mild cleaner (e.g., white vinegar) once or twice through the machine. Cleaning is needed depending on usage, but in most cases, should be done every 2-3 weeks.

Durability and Reliability

Most Keurig and Nespresso models are can be expected to last 2-5 years, but much depends on usage and proper maintenance. Both companies offer a limited one-year warranty on all models, but some licensed manufacturers may extend that warranty up to two years on certain models.

Pods and capsules are rated to maintain freshness for up to 18 months, provided the container itself is not altered in any way. However, the flavor and coloring of some grounds may fade much sooner due to higher amounts of volatile compounds.

Market Share

Nespresso is the global market leader in unit sales of machines and single-serve units, with the bulk of its sales in Europe and Asia. Keurig is the best-selling coffee maker of its type in the U.S., but Nespresso continues to have a slight edge in sales among premium coffee drinkers (about 28-36% of the global market).[3]

Environmental Impact

Neither Keurig K-cups nor Nespresso capsules are recyclable. For K-Cups, the plastic and foil construction makes separating the components difficult, while Nespresso capsules combine aluminum and lacquer. This means that each pod or capsule ends up as landfill waste.

Nespresso does have a limited recycling plan in some European countries and a "return the empties" plan using pre-paid boxes. K-cups are often reused, and companies such as Ekobew create special reusable options, but this is done manually by machine owners and is not a company policy. In any case, these efforts are only a tiny amount of recycling amid millions of pods and capsules discarded each week.
