The Jocuu Slow Masticating Juicer at 150W is a cold-press masticating juicer that operates at 40 to 80 RPM to extract juice without the heat and oxidation that high-speed centrifugal juicers generate. At 150W with soft and hard mode settings, a reverse function to prevent clogging, and quiet operation suitable for early-morning juicing, the Jocuu targets health-focused buyers who prioritize maximum nutrient retention over juicing speed. This review tests the cold-press extraction performance on the full spectrum of produce: leafy greens, root vegetables, and citrus to see whether the slow masticating approach delivers measurably better juice than centrifugal alternatives.
What Is the Jocuu Slow Masticating Juicer?
The Jocuu is a 150W slow masticating juicer that operates at 40 to 80 RPM to extract juice through auger compression rather than the high-speed blade spinning used in centrifugal juicers. The slow extraction process preserves more heat-sensitive nutrients, produces drier pulp, and generates less oxidation than centrifugal juicing, which means the juice stays fresh longer in the refrigerator.
The masticating design is fundamentally different from centrifugal: a single auger screw compresses produce against a strainer screen to squeeze out juice, while centrifugal juicers use a rapidly spinning blade to shred produce and force juice outward through centrifugal force. The Jocuu’s 150W motor runs at low RPM with high torque, which handles leafy greens and fibrous vegetables that stall centrifugal juicers.
Specifications and Auger Design
The Jocuu operates at 150W with an auger that rotates at 40 to 80 RPM depending on the produce type and mode setting. The two modes are Soft/Hard: soft mode for citrus, watermelon, and peaches handles high-water-content produce; hard mode for carrots, apples, and leafy greens handles dense, fibrous produce. The 150W motor delivers high starting torque to handle the initial resistance of hard produce without stalling.
The juice container holds roughly 27oz and the pulp container holds 34oz, which supports 3 to 5 juicing sessions before emptying. The auger, strainer, and containers are all BPA-free and dishwasher-safe on the top rack, though hand-washing extends component life.
Soft Mode and Hard Mode
The soft mode setting ramps auger speed to the higher end of the 40 to 80 RPM range for high-water-content produce like citrus, watermelon, peaches, and tomatoes. The hard mode setting maintains lower RPM for dense, fibrous produce like carrots, apples, kale, and ginger. Using the correct mode for each produce type produces higher juice yield and drier pulp than using a single-speed setting.
Reverse Function and Cleanup
The reverse function runs the auger in the opposite direction to clear clogging from fibrous produce like celery and kale. The reverse switch is a practical feature that prevents the frustration of stopped juicing mid-session, which is common with single-speed juicers when processing fibrous ingredients. The Jocuu’s cleanup involves disassembling the auger, strainer, and containers, rinsing each component, and wiping the juicer body. The process takes 5 to 10 minutes per session, which is longer than blender self-cleaning but manageable.
Performance Across Key Tasks
The slow masticating process on the Jocuu produces measurably higher juice yield and drier pulp than centrifugal juicers, with more nutrient retention for heat-sensitive vitamins. The 150W motor handles leafy greens and fibrous vegetables that stall centrifugal juicers. The trade-off is speed: centrifugal juicers process the same quantity of produce in 2 to 3 minutes versus 5 to 8 minutes for the Jocuu.
The nutrient retention advantage of cold-press over centrifugal is most noticeable on heat-sensitive vitamins like vitamin C and glutathione, which degrade rapidly under the heat generated by high-speed centrifugal blade spinning. For health-focused buyers who juice for maximum nutrient density, the slow masticating process delivers measurable advantages.
Leafy Greens and Wheatgrass
The Jocuu handles leafy greens and wheatgrass that overwhelm centrifugal juicers. Kale, spinach, wheatgrass, and parsley contain high fiber that clogs centrifugal blades and produces low yield. The Jocuu’s auger compresses leafy greens slowly without blade contact, extracting juice from the fiber without the stalling that centrifugal juicers experience.
The juice yield from leafy greens is significantly higher than centrifugal: kale yields roughly 30 to 40 percent more juice by weight in the Jocuu than in a centrifugal juicer. The pulp is noticeably drier, which signals that more of the available liquid has been extracted. For health-focused juicers who prioritize leafy green juice, the masticating advantage is meaningful.
Root Vegetables and Hard Produce
The Jocuu handles carrots, beets, ginger, and apples with high yield and consistent extraction. The hard mode setting maintains lower RPM for dense produce, which prevents the aeration and oxidation that faster juicers generate. The juice from root vegetables in the Jocuu is noticeably clearer and less foamy than centrifugal juice, which has practical benefits for juice storage and shelf life.
Ginger root processes well in hard mode, producing concentrated ginger juice that centrifugal juicers handle inconsistently due to ginger’s fibrous texture. For households that use ginger regularly in juices, the Jocuu’s performance is a meaningful advantage over centrifugal alternatives.
Citrus and Soft Fruit
Soft mode handles citrus, watermelon, and peaches efficiently. The higher RPM for high-water-content produce prevents the clogging that hard mode creates with slippery, juicy ingredients. Orange juice from the Jocuu is clearer and less foamy than centrifugal orange juice, with a noticeably longer shelf life in the refrigerator.
The juice yield on citrus is comparable to centrifugal, which is expected since citrus is not fiber-dense. The Jocuu’s advantage on citrus is oxidation reduction rather than yield: the juice stays fresh longer without the brown discoloration that centrifugal juice develops within hours.
How It Compares to Centrifugal Juicers
The Jocuu at 150W produces higher juice yield, drier pulp, less oxidation, and better nutrient retention than centrifugal juicers at equivalent price. The trade-off is speed: the Jocuu processes the same quantity of produce in roughly twice the time. For daily juicers who prioritize nutrient density and juice shelf life over speed, the masticating advantage justifies the extra time.
Who Should Buy It?
Best For: Health-Focused Juice Cleanses and Nutrient Maximization
The Jocuu is the right choice for health-focused buyers who juice for maximum nutrient retention, juice cleanses, and leafy green extraction. The slow masticating process preserves more heat-sensitive vitamins than centrifugal juicing, produces drier pulp with higher yield, and generates juice that stays fresh longer without oxidation.
Not Best For: Speed-First Daily Juice Users
If you want to juice a full day’s produce in under 5 minutes, the Jocuu is not the right choice. Centrifugal juicers process the same quantity in 2 to 3 minutes. See our blender vs juicer comparison for guidance on whether a juicer or a blender smoothie fits your health goals better.
Should You Buy the Jocuu?
Buy the Jocuu if you prioritize nutrient retention, juice yield, and shelf life over juicing speed. Do not buy it if you want the fastest possible daily juicing or expect centrifugal juicer speed from a masticating design.
The slow masticating process is the Jocuu’s defining characteristic. For health-focused juicers, the nutrient retention advantage is worth the extra time. See our best blenders 2026 roundup for blender alternatives if your health goals favor whole-food blending over juicing.
Price and Value vs Cold Press Competitors
The Jocuu is priced competitively against other slow masticating juicers in the same wattage tier. The value case is built on nutrient retention and juice yield: the higher extraction rate means buyers get more juice per pound of produce, which partially offsets the longer juicing time.
Cleanup Time and Daily Maintenance
The Jocuu cleanup takes 5 to 10 minutes per session, which is longer than centrifugal juicer cleanup due to the additional components (auger, strainer, containers). The hand-washing recommendation for the auger and strainer extends component life but adds to the daily maintenance burden.
Motor Longevity and Durability
The 150W motor at low RPM generates less heat and mechanical stress than high-speed centrifugal motors, which extends the Jocuu’s operational lifespan. The slow masticating design is inherently more durable than centrifugal, which means the Jocuu typically outlasts centrifugal juicers at equivalent price points.
Frequently Asked Questions
