Q: Will fennel make my juice taste strongly like licorice?

No. The raw fennel bulb has a very mild anise or licorice note, much subtler than fennel seeds. When paired with apple, citrus, or cucumber, the flavor stays light and works as a background note rather than overpowering the juice.

Chefs and juice makers love it because it adds a clean, aromatic lift without heavy sweetness. Studies note a range of useful compounds in the plant that support heart and digestive health, which is why it shows up in both kitchens and herbal remedies.

Frequently Asked Questions

Will fennel make my juice taste strongly like licorice?

Fennel has a mild anise or licorice note, but the raw bulb is far subtler than the seeds. With the proper know-how, it shouldn’t even be overwhelming. Fennel, tastewise, is meant to lift.

Fennel paired with bright citrus, apple, or cucumber becomes pleasant, like a background note that rounds the blend. Use a small amount at first and taste as you go.

Fennel is safe for most people when used as a food. Avoid large medicinal doses if you are pregnant or breastfeeding without medical advice.

Those with allergies to plants in the carrot family should be cautious. If you have a chronic condition or take prescription drugs, check with your healthcare provider before adding concentrated fennel preparations to your routine.

Start modest and taste as you go. For a 12 to 16-ounce bottle, try 1/4 to 1/2 cup of loosely packed raw bulb, thinly sliced.

If you like a stronger fennel presence, increase the amount. It’s always helpful to balance with some acidity (like lemons).
