Every Keurig here brews the same way. You drop in a K-Cup pod, the machine pierces it and pushes hot
water through, and a mug of filter-style coffee comes out. There is no grinder and no espresso
pressure. What separates the five models is how much water they hold, which cup sizes
they offer, and how much say you get over the strength of the drink.
The K-Cup is an open standard that many brands make, so you are not tied to Keurig's own pods, and
reusable filters let you brew your own ground coffee. That makes the machine choice about space and
features rather than about which pods you are allowed to buy. Our category page for
pod and capsule machines shows where Keurig sits next to the
other systems.
Smallest and cheapestK-Mini and K-Express
A single-cup reservoir under five inches wide, or a 42 oz tank with a Strong Brew button.
Household sizesK-Classic and K-Supreme
A 48 oz tank with 6 oz cups, or MultiStream needles on a 1.95 litre tank.
Most adjustableK-Elite
Five sizes, strength, temperature, iced and hot water on a 2.2 litre tank.
Keurig models explained: K-Mini to K-Elite
The short answer
Five machines, one brewing method. They differ in tank size, cup sizes and controls, from the narrow K-Mini
up to the adjustable K-Elite.
The smallestKeurig K-Mini
The narrowest pod machine Keurig makes, under five inches wide, and the reservoir is the reason. It has no
tank. You pour in the water for the cup you are about to make, a 0.35 litre single-cup reservoir, and that
one decision shrinks it to 114 x 287 x 307 mm with the cord stored in the base. It brews any size from 8 to
12 oz and clears a travel mug 178 mm tall. Because it heats from cold every time, it cannot brew two cups
back to back without a refill, and it is slower per cup than a machine with a tank. In return there is no
standing water to go stale and it fits a desk, a dorm room or a caravan. Strength, temperature and iced
settings are all absent, and the auto shut-off arrives 90 seconds after the last brew.
The cheap workhorseKeurig K-Express
The least expensive machine here with a real reservoir. It holds 42 oz of water in a flip-top tank, weighs
4.1 lbs and measures 4.56 inches wide. It brews 8, 10 and 12 oz, has a Strong Brew button that slows
extraction for a more concentrated cup, and shuts itself off after five minutes. It draws 1001 W and carries
a one-year warranty. There is no frother, no cold brew and no temperature setting, and no internal bin for
spent pods, so you pull each one out by hand. The adjustable cup support takes a travel mug up to 7.4 inches
tall. For a person or a couple who want to spend as little as possible, it covers the ground. If you are
weighing it against the smallest model,

Keurig K-Mini sets out the difference the tank makes.
The mid-size household machineKeurig K-Classic
The plain, button-operated brewer for a house where everyone drinks something different. It holds a 48 oz
removable reservoir, draws 1,470 W and brews 6, 8 and 10 oz. It measures 9.8 by 13.3 by 13.0 inches and
weighs 10 lbs, and the drip tray adjusts to fit different cup heights. The auto shut-off is two hours. The
only lever over strength is the cup size: a 6 oz pour from a pod comes out more concentrated than a 10 oz
pour. There is no strength dial, no temperature control and no pre-infusion, so the pod decides almost
everything. What it adds over the K-Express is a larger tank and a 6 oz size, and
Keurig K-Classic vs
Keurig K-Express is the page to read if those two are close.
The adjustable oneKeurig K-Elite
For the person whose complaint about Keurigs is that the coffee is thin. It offers five sizes from 4 to
12 oz, a strong brew setting, adjustable brew temperature and an iced setting that brews hot over ice. It
also dispenses hot water on demand, which turns it into a kettle for tea, instant soup or filling a
cafetière. The 2.2 litre tank is the largest on the page, and a water filter and handle come in the box. A pod holds a fixed dose of coffee, so the only variables left are how much water and how hot. Strong brew
slows the flow so the water spends longer on the grounds, and a cooler setting suits a light roast that
tastes harsh. Keurig does not publish its wattage, weight or warranty term. It suits a busy kitchen or a
small office. Keurig
K-Classic vs Keurig K-Elite shows what the controls add over the plainer machine.
The multi-needle oneKeurig K-Supreme
Sits above the entry models. Its feature is MultiStream Technology, which wets the grounds through multiple
needles rather than the single-needle approach of a standard Keurig, aiming at better flavor and aroma. It
brews 6, 8, 10 and 12 oz from a 1.95 litre tank and measures 257 by 377 by 366 mm. It has no milk system and
no espresso output. Keurig lists no strength or temperature setting for it, so MultiStream is the whole
pitch. Descaling is manual, the warranty is one year, and Keurig lists no auto shut-off. Keurig also
publishes a K-Cycle mail-in scheme for used pods. For the full field, see the
K-Cup coffee makers we rank across brands.

What to look for when buying a Keurig
The short answer
Count how many cups you make in a row, then decide whether cup size, strength control or iced drinks matter
most. The pod sets the dose, so the machine only changes the water.
Reservoir: a tank, or a single cup of water
Count how many cups you make in a row. The K-Mini needs a refill for every cup, which is fine for one
person and tedious for a household. The K-Express, K-Classic, K-Supreme and K-Elite hold 42 oz, 48 oz, 1.95
litres and 2.2 litres. The largest tanks save refills in an office, and the small ones keep the machine
narrow. Think of the tank as how often you will walk to the sink.
Cup sizes: where your mug falls
The cup size sets how strong the drink is, because the pod holds a fixed dose. The K-Classic and K-Supreme
include 6 oz, the K-Elite goes down to 4, and the K-Express and K-Mini start at 8. If you like a short, strong
cup, look for a machine that offers a small size. If you fill a travel mug, check the 12 oz top size and the
clearance under the spout.
Strength and temperature controls
Most Keurigs give you nothing beyond cup size. The K-Express adds a Strong Brew button, and the K-Elite adds a
strong brew setting and adjustable temperature. If pod coffee tastes weak to you, those controls are the
reason to pay more, and the machine without them cannot fix a thin pod.
Iced and hot water
Only the K-Elite lists an iced setting, brewed hot over ice, and a hot water dispenser. If you drink iced
coffee or tea every day, that narrows the choice at once. The others make hot drinks only.
MultiStream against a single needle
The K-Supreme's multiple needles are an extraction change, aimed at the pod itself. They are a different
approach from the K-Elite's controls: one changes how the water meets the grounds, the other changes the
strength and temperature of the water. Treat MultiStream as Keurig's design claim rather than a proven step up in the cup.
Keurig problems and drawbacks
The pod decides the cup
A K-Cup contains a set amount of coffee, and none of these machines can grind or dose. A thin pod makes a
thin drink, and only the K-Elite offers controls to compensate. For better flavor the answer is a better pod
or a reusable filter and your own grounds, and K-Cup pods we rank is the place to
start.
No milk, no espresso
None of the five has a milk system, a frother or espresso pressure. Lattes and cappuccinos need a separate
frother, and the drinks are filter-style, not espresso. If milk drinks matter, a pod machine with a
milk system belongs on your list instead, and Nespresso machines is a
good place to look.
Chores and thin specs
Spent pods come out by hand on the K-Express and K-Classic, and descaling is required on every model that
states it. Keurig leaves gaps in what it publishes: no wattage, warranty or weight for the K-Mini, no
warranty or weight for the K-Elite, no auto shut-off for the K-Supreme. Check the listing before you buy if
one of those matters to you.
Plastic pods
A K-Cup is a number 5 plastic cup. Keurig publishes a K-Cycle mail-in program and local recycling where
accepted, after you peel the lid and empty the grounds. It is more work than putting a pod in the bin.

Keurig running costs: pods, reusable filters and descaling
Why it matters
Pods are the running cost, and they are where the money goes over a few years.
Running costA reusable filter
A reusable My K-Cup filter lets you brew ground coffee and cuts the cost per cup. It comes separately on the
K-Mini, and is available for every model here. Our guide to pod cost per cup works through the arithmetic.
Upkeep and fitDescaling and a mug that fits
Plan for descaling, which is required on the models that state it, and for a mug that fits. Travel mug
clearance is 178 mm on the K-Mini and up to 7.4 inches on the K-Express. If you want something fresher than a
pod, compare bean-to-cup against pod machines.
Which Keurig should you buy?
A desk or a dorm, one cup at a time
Start with where it will sit and who will use it. For a desk or a dorm, buy the K-Mini.
One or two people, cost matters
A kitchen where one or two people drink a mug each day and cost matters: the K-Express.
A bigger household
A household that wants smaller cups and a larger tank: the K-Classic.
Weak coffee, iced coffee or tea
If you find pod coffee weak, or you drink iced coffee or tea, the K-Elite is the one built to be adjusted.
The multi-needle approach
If you want the multi-needle approach on a mid-size tank, choose the K-Supreme. Our top picks at the top of
the page set out the reasoning.
Keurig vs Nespresso and other pod machines
Keurig's open K-Cup system
Keurig's K-Cup system is open to many brands of pod, which keeps pod prices competitive and lets you use a
reusable filter.
Nespresso, the closest rival
Nespresso is the closest rival format, with a closed Vertuo line and an open Original one, and it
makes espresso and milk drinks that Keurig does not. Keurig K-Mini vs Nespresso
Pixie shows the two approaches on small machines.
Keurig is one of several pod systems we score on the same criteria, and the whole group sits in our pod and
capsule category.
