Can You Put Wheatgrass in a Centrifugal Juicer?

Yes, you can put wheatgrass in a centrifugal juicer, but it is not ideal. Centrifugal juicers spin at high speeds (10,000–15,000 RPM), which creates heat and foam, leading to rapid oxidation and lower juice yield compared to slow masticating juicers. Expect only about 40–50% juice yield from wheatgrass, and the juice will start degrading within minutes. However, if a centrifugal machine is all you have, you can still get usable juice with a few adjustments.

Quick Answer

Centrifugal juicers work for wheatgrass but with trade-offs. They produce less juice, more foam, and faster nutrient loss. Masticating juicers are better, but if you already own a centrifugal model, use these tips to improve results.

Yield: Centrifugal juicers extract only about 40–50% juice from wheatgrass vs. 70–80% with a masticating juicer.
Oxidation: High-speed spinning introduces air and heat, causing wheatgrass juice to oxidize within 15–30 minutes.
Foam: Centrifugal action creates significant foam, which can separate and reduce usable liquid volume.
Cleaning: Wheatgrass fibers clog centrifugal filters quickly; must be cleaned immediately to avoid buildup.
Preparation: Cut wheatgrass into 1–2 inch pieces and pack the chute tightly to improve extraction.

How to Juice Wheatgrass in a Centrifugal Juicer

Start by washing the wheatgrass thoroughly to remove any dirt or debris. Cut the grass into 1–2 inch lengths using kitchen shears or a knife. This prevents long strands from wrapping around the blade or clogging the chute.

Assemble your centrifugal juicer according to the manual. Feed the wheatgrass pieces into the chute a handful at a time, using the pusher to gently press them down. Do not overload; let the machine process each batch before adding more. Collect the juice in a glass or container placed under the spout.

Expect a foamy, green liquid. Stir the juice with a spoon to incorporate the foam, or let it settle for a minute. Drink immediately for best taste and nutrient retention. If you must store it, use an airtight container in the fridge and consume within 4 hours.

Centrifugal vs. Masticating Juicer for Wheatgrass

Masticating juicers (also called slow juicers) crush and press wheatgrass at low speeds (40–80 RPM), producing up to 80% juice yield with minimal oxidation. The juice stays vibrant green for 24–48 hours when refrigerated. Centrifugal juicers, by contrast, spin at high speeds, generating heat that destroys enzymes and causes rapid browning.

If you plan to juice wheatgrass regularly, a masticating juicer is a better investment. Models like the Omega NC800 or Hurom H-AA are specifically designed for leafy greens and grasses. However, if you already own a centrifugal juicer (e.g., Breville Juice Fountain or Cuisinart), you can still use it—just adjust expectations for yield and freshness.

Tips for Better Wheatgrass Juice from a Centrifugal Juicer

Chill the wheatgrass in the fridge for 30 minutes before juicing to reduce heat buildup.
Run the juicer at the highest speed setting (if adjustable) to maximize centrifugal force.
Juice wheatgrass alone, not mixed with hard produce like carrots or apples, as the fibers can jam the machine.
Use a fine-mesh strainer or cheesecloth to filter out pulp and foam if you prefer a smoother juice.
Clean the filter basket immediately after juicing with a stiff brush under running water to prevent clogging.

Common Mistakes When Juicing Wheatgrass in a Centrifugal Juicer

Feeding whole, uncut wheatgrass: Long blades wrap around the spinning blade, reducing efficiency and causing motor strain.
Packing the chute too tight: Overstuffing can stall the motor or cause the machine to overheat. Feed gradually.
Waiting to clean: Dried wheatgrass fiber hardens and becomes nearly impossible to remove from the mesh filter. Rinse right away.
Drinking juice too late: Wheatgrass juice from a centrifugal juicer loses nutrients fast—consume within 30 minutes.
Using a dull blade: A sharp blade is critical for cutting grass fibers. Replace the blade according to the manufacturer’s schedule.

How to Clean a Centrifugal Juicer After Wheatgrass

Unplug the machine immediately after juicing. Disassemble the parts: pulp container, juice jug, filter basket, and lid. Rinse the filter basket under hot running water from the back side (the side opposite the blade) to push trapped fibers out.

Use a nylon brush to scrub the mesh thoroughly. For stubborn residue, soak the basket in hot water with a drop of dish soap for 10 minutes, then scrub again. Avoid abrasive pads that could damage the fine mesh. Dry all parts completely before reassembling to prevent mold.

Pro Tips

Freeze wheatgrass in ice cube trays after juicing to preserve it for up to 3 months—thaw cubes in the fridge before drinking.
Alternate wheatgrass with a piece of ginger or lemon in the chute to help push fibers through and add flavor.
If your centrifugal juicer has a blank pulp screen (for soft fruits), use it instead of the standard screen for slightly higher yield.
Line the pulp container with a plastic bag for easier cleanup—wheatgrass pulp is very fibrous and sticky.

Common Mistakes to Avoid

Juicing wheatgrass that is too mature or yellowed—it yields bitter juice and less liquid. Use bright green, tender grass.
Adding wheatgrass to the juicer with other high-fiber greens like celery—this can overload the machine and cause clogging.
Storing juice in a metal container—metal accelerates oxidation; use glass or BPA-free plastic.
Not balancing the pulp container—wheatgrass pulp is light but can cause the container to tip if unevenly filled.

FAQ

Can I mix wheatgrass with other fruits in a centrifugal juicer?

Yes, but it’s best to juice wheatgrass first, then juice harder produce like apples or carrots. This helps push the grass fibers through and reduces clogging. Avoid mixing with soft fruits like oranges directly, as the pulp can create a pastey mess.

How long does wheatgrass juice last from a centrifugal juicer?

Wheatgrass juice from a centrifugal juicer should be consumed within 30 minutes for maximum nutrient retention. After that, oxidation causes rapid degradation. If refrigerated in an airtight glass container, it may last up to 4 hours, but flavor and quality decline quickly.

Do I need to dilute wheatgrass juice?

Wheatgrass juice is very concentrated and can be strong-tasting. Many people dilute it with water, apple juice, or coconut water at a 1:1 ratio. Start with a small amount (1–2 ounces) to see how your body reacts, especially if you’re new to wheatgrass.

The Bottom Line

While a centrifugal juicer isn’t the best tool for wheatgrass, it can still produce drinkable juice if you follow the right preparation and cleaning steps. For regular wheatgrass juicing, consider investing in a masticating juicer—it will give you higher yields, better nutrition, and less hassle. In the meantime, use the tips above to get the most out of your centrifugal machine.
