Senseo pods: how the system works and why a cup costs least

A Senseo pod is a soft paper pillow of ground coffee, and it already looked dated back when aluminium capsules first reached the shelves. It still sells anyway, and there is one very specific reason for that: the price of a cup. Of every system you can buy ready-made and simply drop into a machine, a Senseo pod gives you the cheapest drink there is. So the question Senseo pods or coffee capsules is not about which of them is more modern, but about what drink you want and how much you are willing to pay for it. This article answers both — including what Senseo cannot do, and where capsules clearly beat it.

How Senseo works and what comes out of a pod

Senseo is a system that came out of a collaboration between a coffee machine maker and the roastery Douwe Egberts. Mechanically it is the simplest capsule or pod system you can buy: a soft pod lies in the holder of the machine, hot water passes through it, and coffee runs into the cup. No grinder, no tamping, no dosing.

The pod itself is nothing but ground coffee between two layers of filter paper. Nothing more — no plastic, no aluminium, no inner foil. Almost everything about it, the good and the bad alike, follows from that one fact.

Low pressure means a different drink

This is the single most important sentence in the whole article: Senseo does not make espresso. Espresso happens when water is forced through very finely ground coffee at high pressure. Senseo works at markedly lower pressure and with a coarser grind, so what comes out of a pod is a longer, gentler coffee with a layer of foam on the surface. That foam looks like crema, but it is not created the same way and it does not have the same density.

The practical upshot: if you drink small short espressos and judge them by how well the crema holds, Senseo will disappoint you. If you drink a big mug of coffee first thing in the morning, it is exactly the drink you want — and it is ready in tens of seconds with no input from you at all.

One pod, one cup — or two

Machines for Senseo pods usually come with two holders: one for a single pod and one for two pods. The two-pod holder does not make stronger coffee, it makes two cups at once. When you want a bolder coffee, the answer is not more pods but a bolder pod and a smaller cup.

This is a common misunderstanding. It works much the same with capsule systems: intensity is not set by the amount of water, but by what is inside. We go through the differences between the systems in detail in our guide to how to choose coffee capsules.

Senseo pods or coffee capsules: what is the difference

The difference is not only in the wrapper. A pod and a capsule differ in pressure, in the drink, in the waste and in the price — and any one of those four can be the deciding one for somebody.

Read the price-per-drink column as a whole, not as a ranking of the cheapest wrappers. With Tassimo one milk drink needs two capsules, so a pack labelled sixteen capsules is a pack for eight drinks — and the price per drink is therefore twice the price per capsule. Senseo has no such trap: one pod is always one cup.

Where the pod has an advantage capsules cannot match

Besides the price, the pod has two strengths that follow straight from the way it is built. The first is waste: the pod goes into food waste whole, coffee grounds and all, and there is nothing to empty out and nothing to separate. The second is that there is nothing in a pod except coffee and paper — no foil, no dye, no code for the machine to read.

Where the capsule has an advantage the pod cannot match

A capsule is hermetically sealed away from oxygen, so the coffee inside keeps its aroma for a year or more. A pod is paper and permeable — the outer bag protects it, but once that bag is open the coffee starts to age. The second thing is the breadth of the range: capsule systems have dozens of roasteries behind them, pods far fewer. And the third is the drink itself: you will make neither espresso nor milk drinks from a Senseo pod.

Which machine Senseo pods belong in, and which they do not

A Senseo pod belongs in a machine built for soft pods. In practice that means a Senseo machine — other machines with a holder of the same size do exist, but they are rare, so if you have a saucer-sized pod in the cupboard you almost certainly have a Senseo.

What does not work:

• A portafilter machine with a basket for E.S.E. pods. That basket is 44 mm across, a Senseo pod is a good deal bigger and will not go in at all. It does not work the other way round either: an E.S.E. pod gets lost in a Senseo holder and the water simply runs around it. We go through the differences between the two pods in our article on what E.S.E. pods are.
• Capsule machines. Nespresso, Dolce Gusto, Tassimo and Cafissimo will not take a soft pod — their holders are shaped for one specific capsule.
• A bean-to-cup machine. It grinds its own coffee, and there is nowhere in it for a pod to go.

If you are not sure what you have at home, diameter and firmness settle it. A Senseo pod is big and soft, and you can bend it between your fingers. An E.S.E. pod is smaller and firmer. A capsule is a hard little container, not a pillow. We have an overview of machines by system in our article on the best capsule coffee machine, and the full range in capsule machines.

What a single cup costs

With pods the arithmetic is simple, because one pod is one drink. Divide the price of the pack by the number of pods and you have the price of a cup — none of the conversions Tassimo forces on you.

A big pack is not automatically cheaper

The table shows up something worth reading twice. A pack of 48 pods at $18.69 works out at $0.39 a pod, which is dearer than a pack of 18 pods at $6.68, where a pod comes to $0.37. Volume on its own does not buy you a discount — what decides is the particular roastery and the particular line.

The lowest price per cup in our range does happen to belong to the biggest pack, but in the darker version: 48 pods at $14.94, which is $0.31 a drink. If a darker roast suits you, that is the cheapest way there is to make coffee out of a ready-made pack.

When ground coffee is still cheaper

Let us be honest about it: ground coffee in a big bag works out cheaper per cup than any pod. The difference is that you have to dose it, tamp it and clear up after yourself. A pod is convenience, and you pay a small premium per cup for it — a smaller premium, set against a capsule, than with any other alternative.

Which Senseo pods to choose

Inside the system, pods differ only in the roast and in the blend of varieties. Structurally they are all the same, so you cannot come unstuck on compatibility — only on taste. The whole range of pods for Senseo sits in one place; here is a guide to it based on how you drink.

A milder coffee for every day

If you drink a big mug and do not want anything assertive, reach for a lighter roast. Jacobs Crema Pads are built for exactly that drink — foam on the surface, a body on the gentle side. Douwe Egberts Senseo Mild Roast lands in much the same place, and it comes from the roastery that stood at the very beginning of this system.

Bolder and darker

When a mild coffee tastes empty to you, go for a version labelled strong or dark. Jacobs Crema Pads Kräftig and Douwe Egberts Senseo Strong are darker roasts with more bitterness and a fuller body. With the low pressure of Senseo that tends to be the difference you notice most: a light coffee from a pod can come out watery, while a darker one holds its body even in a longer drink.

Watch out for the word “espresso” on the pack

The pods Lavazza Espresso Classico and Lavazza Espresso Intenso have espresso in the name, but no espresso will come out of them in a Senseo machine. The name points to the style of roast the Italian roastery uses for espresso — darker, with a higher share of robusta and a fuller body. In a Senseo machine it turns into a longer coffee with a strong finish, not a short espresso in a small cup. It is a good choice when you want the most character a pod can give you, but it is only fair to say that the name on the box describes the coffee, not the drink the machine will hand you.

Decaf and the other brands

A decaffeinated version does exist within the system, and it tastes less different from the regular one than people expect — you will find it among the decaf Senseo pods. Besides Jacobs and Lavazza, pods for this system are made by Gimoka as well, so the choice is not narrowed down to two names.

How many to buy the first time

Start with a small pack. A pod is not a hermetic capsule: as long as the bag is closed the coffee holds up, but once it is open oxygen gets at it and the aroma fades faster than it would in a capsule. Buying two hundred pods of one taste in a single go therefore makes no sense until you know it suits you. We go through how long coffee keeps in general in our article on how long coffee lasts.

What Senseo cannot do

The system has been on sale for twenty years, and there is plenty about it that today looks like a concession. It pays to know all of it before you stand the machine on the worktop.

• No espresso and no ristretto. Low pressure simply will not allow it. Anyone who wants a short coffee with a dense crema needs a portafilter machine or a capsule system.
• Milk drinks by hand only. There is nothing but coffee in a pod, so the machine will not put together a latte macchiato or a cappuccino by itself. You have to froth the milk separately. That is the main reason households with children tend to buy Dolce Gusto instead — we describe how that system works in our article on Dolce Gusto.
• A narrower choice of roasteries. Several dozen brands supply capsules for Nespresso, and far fewer supply Senseo. If you like trying new coffees, you will reach the end of the range here sooner.
• Aroma once the bag is open. A paper pod is no barrier against oxygen. A capsule keeps for years, an opened pack of pods for weeks.
• Few ways to fine-tune the drink. You influence the taste by the pod you pick and the size of the cup, and that is all. Anyone who wants to get at the grind size and the dose is better served by a grinder.

And one more thing, which does not show up in any list of features but turns up after a few months: the machine needs descaling like any other coffee machine. It heats water the same way as the rest of them, and limescale takes its performance away, so cleaning and descaling products come in useful, and in hard water a water filter does too.

What to do with a pod once you have drunk it

This is the simplest part of the whole system, and at the same time its strongest argument if waste is something you care about. A used pod goes into food waste whole — paper and coffee grounds together, with nothing to separate and nothing to empty out. You can also put it on the compost heap, or under plants that tolerate slightly acidic soil.

Compare that with a capsule. An aluminium capsule has to be emptied out and the aluminium handed in with metals; a plastic one emptied out and the shell put in with plastics. Left full, the whole capsule ends up in landfill, because the sorting line cannot split the shell from the grounds. Take-back schemes run by the makers deal with that, but always only for the capsules of the brand in question.

A practical note on running the machine: rinse the pod holder out if a pod has been sitting in it for a while. Damp grounds in wet paper are a breeding ground for mould, and they leave a smell behind in the holder that the next coffee will pick up.

Frequently asked questions

Which coffee machine do Senseo pods fit?

A machine for soft pods, which in practice means a Senseo machine. They will not fit a portafilter machine with a basket for E.S.E. pods, because that basket is 44 mm across. They do not go into capsule machines or bean-to-cup machines at all.

How do I tell a Senseo pod from an E.S.E. pod?

By size and firmness. A Senseo pod is about as big as a saucer, and you can bend it between your fingers. An E.S.E. pod is 44 mm across, smaller and firmer, because in a portafilter machine it has to stand up to high pressure. Put them side by side and mixing them up is impossible.

Can you make espresso from a Senseo pod?

No. Espresso needs high pressure and a very fine grind, and Senseo works with low pressure and coarser coffee. What comes out of a pod is a longer, gentler drink with foam on the surface. Even a pod labelled espresso will not change that — the word describes the roast, not the drink you end up with.

Will two pods make stronger coffee?

Not in the way people expect. The two-pod holder is there for two cups at once, not for one stronger cup. Stronger coffee comes from a bolder pod and a smaller cup.

Are Senseo pods cheaper than coffee capsules?

Yes, and clearly so. In our range a drink from a pod works out cheapest of all the systems where you buy a ready-made portion and simply put it in the machine. Against milk capsules the gap is a factor of two or more, because with those you are paying for the milk component as well.

How long do pods keep?

A long time in an unopened bag, and markedly less time than a capsule once the bag is open. A capsule is sealed away from oxygen and holds its aroma for a year or more, while a paper pod is permeable. So use an opened pack up within a few weeks, and keep it in a sealed container.

Are there decaf Senseo pods?

Yes, they have a line of their own within the system. Modern decaffeination keeps most of the aroma, so the difference in taste is smaller than people usually expect.

Can you put ground coffee in a Senseo without a pod?

The machine is built around the pod, and its holder assumes the paper will hold the coffee in. Loose ground coffee will pass through into the drink and into the machine itself. Anyone who wants to dose their own coffee needs a different type of machine.

Summary and recommendations

Senseo is a system with one clear job: to give you a convenient mug of coffee at the lowest possible price per cup. At that it is the best of anything you can buy ready-made. Do not buy it expecting espresso or milk drinks, though — low pressure will not produce a short coffee with a dense crema, and there is no milk in a pod.

The practical decision is a simple one. If you drink a big mug and want as little work and as low a price as possible, go for pods. If you drink short espressos or a latte macchiato, reach for coffee capsules and pay the difference. And if what you want above all is the lowest price and you do not mind dosing, ground coffee wins.

When you are picking a particular pod, hold on to two things. First, count the price per pod, not per pack — volume on its own does not buy a discount, and the biggest box is often dearer per cup than a small one. Second, start with a small pack, because a pod ages faster than a capsule once the bag has been opened, and two hundred pods of a taste that does not suit you is an expensive lesson.
