Cold-Pressed
Cold-Pressed vs Centrifugal: What Actually Changes
Both machines turn vegetables into juice. They do it by completely different means and the results are easy to tell apart once you know what to look for. Here is how each one works, what the pulp tells you, where masticating juicers fit in and which is worth the money depending on what you actually drink.
Shredding Versus Squeezing
A centrifugal juicer shreds produce against a blade spinning at thousands of revolutions a minute, then flings the juice outward through a mesh screen. It is fast, cheap and violent. A press grinds produce into a pulp first, then squeezes that pulp under several tonnes of pressure until the liquid is gone. It is slow, expensive and gentle.
Everything else follows from that one difference. If you want the method explained on its own terms, start with what is cold-pressed juice.
Look at What Gets Thrown Away
The photograph at the top of this page is the whole argument in one frame. On the left, pulp from a press: a dry compressed cake that holds its shape, with the liquid genuinely gone. On the right, pulp from a centrifugal machine: wet, slumped and still leaking juice onto the slate.
That puddle is the point. Everything still in the wet pulp is juice you bought and did not drink. A press gets more out of the same produce, which is why a bottle from a press represents more vegetables than the same volume from a spinning blade.
The glasses tell the same story from the other end. Press juice is dense and evenly coloured. Centrifugal juice arrives with a thick pale head of foam on top, because the blade whipped air through it on the way out. That foam is oxidation beginning before you have even taken a sip.
How They Compare
| Cold press | Centrifugal | |
|---|---|---|
| Method | Ground, then pressed under pressure | Shredded against a spinning blade |
| Speed of the mechanism | Slow and steady | Thousands of revolutions a minute |
| Heat | None generated | Modest warming from friction |
| Air introduced | Very little | Considerably more, hence the foam |
| Yield | Higher. Dry pulp | Lower. Wet pulp |
| Leafy greens | Handles spinach, kale and celery well | Poor. Leaves mostly pass through |
| Time to make a glass | Slower | Very fast |
| Keeps in the fridge | Holds colour and flavour longer | Separates and dulls quickly |
| Cost of the machine | High | Low |
Where Masticating Juicers Fit In
Search this comparison and you will quickly meet a third term. Masticating juicers, also sold as slow juicers or cold press juicers, use a single auger that turns at well under a hundred revolutions a minute, crushing produce against a screen and squeezing the juice through as it goes.
They sit much closer to a press than to a centrifugal machine. No meaningful heat, far less air, good yield and they handle leafy greens properly. For home use they are the sensible upgrade and most of what gets called a cold press juicer in a domestic kitchen is one of these.
Strictly speaking a true cold press is a two-stage hydraulic system: grind first, then press the pulp separately under tonnes of pressure. That is commercial equipment and it is what produces the dry cake in the photograph. The distinction matters less than the marketing suggests, though. A masticating juicer at home gets you most of the way there.
Which One Should You Get
| Go centrifugal if | Go masticating if |
|---|---|
| You juice occasionally rather than daily | You want to juice most days |
| You mostly juice hard produce like apples and carrots | You want spinach, kale, celery and herbs in the glass |
| Speed matters more than yield | You would rather not throw away wet pulp |
| You want to spend as little as possible | You will use it enough to justify the price |
If you would rather use a blender than buy a juicer, juicer vs blender walks through the blend-and-strain method. Both machines need cleaning immediately after use and that is the honest reason most home juicers end up in a cupboard. A machine is a commitment to washing a mesh screen every single morning, which is a different proposition from buying a juicer.
What This Means on a Shelf
Almost all bottled juice worth drinking is pressed rather than spun, so the method is rarely the thing separating one bottle from another. Two other questions matter more.
What is in it, read in order of weight on the ingredients list, because that decides the sugar far more than the machine does. And what happened to it after pressing, because raw juice lasts days rather than months and every brand solves that differently. We freeze ours at the moment of pressing, so nothing is added and nothing is treated. That is covered properly in frozen versus fresh and in how long cold-pressed juice lasts.
Pressed, Then Frozen
Everything we make comes off a press and goes straight into the freezer:
| Range | Pick this if |
|---|---|
| Beetroot juices | You want the most-researched vegetable in the aisle |
| Green juices | You want the leaves a domestic juicer struggles with |
| Celery juice | You want the lowest sugar of the lot |
| Carrot juices | You are new to vegetable juice and want the easiest way in |
| Juice shots | You would rather have something small and concentrated |
| Cleanse programmes | You want a structured multi-day set |

Frequently Asked
What is the difference between cold-pressed and centrifugal juice?
A centrifugal juicer shreds produce against a blade spinning at thousands of revolutions a minute and flings the juice out through a mesh. A press grinds produce and squeezes it under pressure. The press generates no heat, introduces far less air and gets more out of the same produce.
Is a masticating juicer the same as a cold press?
Not strictly, but close enough for home use. A masticating juicer crushes produce with a slow auger against a screen. A true cold press grinds first, then presses the pulp separately under tonnes of pressure, which is commercial equipment. Both avoid heat and handle greens well.
Why does centrifugal juice go foamy?
The blade whips air through the juice as it spins and that air forms a head of foam. It is also the start of oxidation, which is why centrifugal juice dulls and separates faster than pressed juice does.
Which juicer is best for leafy greens?
A masticating or press-style machine. Centrifugal juicers struggle with spinach, kale and herbs because leaves are light and largely pass through the mesh rather than being crushed. If greens are the point, a spinning blade is the wrong tool.
Does a centrifugal juicer destroy nutrients?
Not destroy, but it is harder on the juice. Friction creates modest warming and the blade introduces a lot of air and air and heat are what degrade juice over time. The bigger practical loss is yield, since wet pulp means juice left behind.
Is a cold press juicer worth the money?
If you juice most days and want greens in the glass, yes. If you juice occasionally and mostly use apples and carrots, a centrifugal machine is fine. The deciding factor is usually whether you will clean it every morning, which is what stops most home juicing.
The Bottom Line
A centrifugal juicer shreds and spins. A press grinds and squeezes. The press wins on yield, on greens, on foam and on how long the juice holds up and the pulp is the proof: dry cake against a wet pile still leaking juice. For home use a masticating juicer gets you most of the way there for a fraction of the price of commercial kit. And whichever machine you use, what goes in still matters more than what happens to it, so read the ingredients before you judge the method.
