A masticating juicer uses a slow-rotating auger to crush and press produce at 46–100 RPM, extracting more nutrients and yield than high-speed models while generating less heat and noise.
If you’ve ever watched juice foam up and quickly turn brown from a centrifugal machine, you’ve seen oxidation in action. The auger literally chews through produce at roughly 1% of the speed of a standard blender, which keeps heat low, foam minimal, and nutrients intact. Serious juice drinkers choose this type for leafy greens and fibrous roots, though the trade-off is more prep work and cleaning time.
How It Actually Works
The term “masticate” means to chew, and that’s exactly what a single auger does—it pulls produce in, crushes it against a sharp screen, and separates juice from pulp in one pass. Unlike centrifugal models that spin at 6,000–14,000 RPM, masticating juicers rotate between 46 and 100 RPM. This slow action prevents the heat that can degrade vitamins and enzymes, which is why brands like Hurom describe their units as a “drill or screw” mechanism. The result is thicker juice with less foam and more fiber, though some people find the texture pulpy or chunky with leafy greens.
What Makes It Different From Centrifugal and Cold Press
Understanding the three main juicer types helps you pick the right one. Masticating sits between a fast centrifugal and a two-stage hydraulic cold press in both price and juice quality. The table below covers the key differences.
| Type | Speed | Best For | Trade-Offs |
|---|---|---|---|
| Centrifugal | 6,000–14,000 RPM | Quick juice, hard produce (beets, carrots) | More foam, heat destroys enzymes, lower yield |
| Masticating (slow) | 46–100 RPM | Leafy greens, fibrous veggies, nutrient retention | More prep, smaller feed chute, longer clean |
| Hydraulic cold press (two-stage) | Extremely slow | Commercial juice bars, clearest juice | Expensive, bulky, requires more steps |
What It Excels At and Where It Falls Short
Masticating juicers shine with kale, spinach, wheatgrass, and fibrous roots like carrots and beets because the auger’s slow grinding extracts more liquid from tough cell structures. Serious Eats testing found they produce less waste and higher yield than centrifugal models, which can save money on produce over time. The juice stays vibrant longer because less air is incorporated during extraction.
But the downsides are real. Breville’s comparison of masticating and centrifugal juicers notes that you’ll need to cut produce into smaller pieces to avoid jamming the auger, and cleaning involves disassembling more parts—the screens and auger require thorough wiping. Some vertical models also have strict 30-minute duty cycles; running one past that limit can overheat and damage the motor. If you’re in a rush each morning, a centrifugal juicer may save time despite the lower nutrient retention.
How to Use One: Prep, Feed, Extract, Clean
The process is straightforward but different from a fast juicer:
- Prep: Wash and cut produce into pieces that fit your machine’s feed chute—smaller than what centrifugal models handle.
- Feed: Insert pieces gradually; the auger pulls and crushes them automatically.
- Extract: Juice exits the spout while dry pulp ejects separately. You’ll see less foam and a thicker consistency.
- Clean: Disassemble all components and rinse immediately. The screen and auger need a quick scrub before pulp dries—leaving it too long makes cleaning a real chore.

FAQs
Is masticating juice actually healthier than centrifugal juice?
Why does my juice from a masticating juicer taste bitter sometimes?
Bitterness usually comes from over-extracting certain greens or from pressing produce that isn’t fully fresh. Kale, dandelion greens, and the white pith of citrus can become bitter when crushed extensively. Mixing sweeter fruits like apple or carrot helps balance the flavor.
Can I make nut milk or sorbet in a masticating juicer?
Many masticating models can handle soaked nuts for homemade almond or cashew milk, and some come with special attachments for fruit sorbet by freezing produce first. Check your model’s manual—vertical auger units are better with nuts than horizontal ones, but neither replaces a dedicated blender for smooth, creamy results.
