A delicate, nutty oil for finishing and dressings
Bulk walnut oil is pressed from the kernels of English walnuts (Juglans regia). It has a soft, toasty, nutty flavor that chefs use to finish salads, vegetables, pasta and desserts, and bakers use to bring walnut flavor to breads, cakes and pastries. Walnut oil is also one of the few nut oils with a meaningful amount of plant omega-3, alpha-linolenic acid.
Our walnut oil is pressed, tested and packed in the United States from US-grown and imported walnuts, and supplied from 1-liter bottles to 20,000-liter flexitanks.
Walnut oil grades

|---|---|---|---|
| Flavor | Delicate, fresh walnut | Deep, toasted walnut | Light, mild |
| Heat | No or low heat | No or low heat | Sautéing and baking, about 204 °C (400 °F) smoke point |
| Best for | Dressings, finishing, cold dishes | Finishing, sauces, gourmet retail | Baking, cooking, food manufacturing |
| Nut protein | Present | Present | Largely removed |
Handle with care: a polyunsaturated oil
Walnut oil is around 57–65% linoleic acid and 9–14% alpha-linolenic acid. That is what gives it its nutritional profile, but it also makes it more sensitive to heat, light and air than most cooking oils. It is not a frying oil. Heat turns its flavor bitter, so cold-pressed and roasted walnut oils are best used raw or added at the end of cooking.
To keep it fresh, we fill walnut oil into full, sealed containers, and we recommend smaller packs for buyers who use it slowly. Once opened, keep it cool, ideally refrigerated, and use it within a few months.
How bulk walnut oil is priced
Walnut oil is a premium oil: walnuts are a valuable nut and yield less oil per ton than oilseeds. Prices follow the walnut crop. Roasted and cold-pressed grades cost more than refined. Each grade is quoted separately on pack size, total volume and destination; the minimum is 1,000 liters per quote.

Sourcing
From walnut orchards to finished oil
Our walnut oil is pressed, tested and packed in the United States from US-grown and imported walnuts. Walnuts are harvested in autumn, hulled, dried and cracked, and only sound kernels go to the press.
For roasted oil, kernels are gently roasted first. Cold-pressed and roasted oils are filtered only; refined oil is refined for a lighter flavor. Every batch is tested and packed at our US facilities.
Processing

Hulling and drying
Harvested walnuts are hulled and dried to protect kernel quality.
Cracking and sorting

Roasting (roasted grade)
Kernels are gently roasted for a deeper flavor.
Pressing
Kernels are mechanically pressed to release the oil.
Filtering or refining
Cold-pressed and roasted oils are filtered; refined oil is refined for a light flavor.
Testing and packing
Each batch is tested, then filled into full, sealed containers.

FAQ
Walnut Oil questions
What is the minimum order?
1,000 liters (about 264 US gallons) per quote, across any combination of oils, grades and pack sizes. For example, one 1,000L IBC tote, five 200L drums, or 50 cases of 4 × 5L bottles.
Is walnut oil good for frying?
No. It is high in polyunsaturated fat and turns bitter when heated. Use refined walnut oil for baking and light cooking, and cold-pressed or roasted walnut oil raw or at the end of cooking.
Does walnut oil contain omega-3?
Yes. Walnut oil typically contains around 9–14% alpha-linolenic acid, a plant omega-3. Any nutrition claims on your products must follow the rules in your market.
How long does walnut oil keep?
Up to 12 months unopened for refined oil and 9 months for cold-pressed and roasted oil. After opening, keep it cool and use it within a few months.
Is walnut oil a tree nut allergen?
Cold-pressed and roasted walnut oils keep nut protein and must be labeled as a tree nut allergen. In the US, highly refined oils are excluded from the major food allergen definition because refining removes the protein, but rules differ by country, so always confirm the labeling requirements where your product is sold.
How is the price set?
Each grade is priced separately, based on the crop, grade, pack size, total volume and delivery destination. Your quotation shows the price, any freight and other charges, the shipping terms and route, and an estimated arrival date.
