Bulk Walnut Oil

Our bulk walnut oil comes from sunny California, which is home to about three quarters of the world’s walnut producers. Walnuts are known for their high content of heart-healthy fats, including omega-3 fatty acids. They’re also rich in protein, fiber, essential vitamins like vitamin E and B6, and minerals like magnesium and phosphorus. Walnuts are packed with antioxidants, supporting overall health. 

Refined walnut oil, extracted from these walnuts, is a versatile ingredient used in various applications, including woodworking and artistry. Its resistance to water solubility makes it suitable for enhancing wood finishes and preserving woodwork. Artists also value it as a quick-drying base thinner for oil paints and an effective brush cleaner.

Caloy is committed to quality, using mechanical expression and refined techniques in the extraction process, without the use of solvents, to maintain the purity of our nut oils. Choose Caloy for premium walnut oil, reflecting a tradition of quality.

Food-Grade Walnut Oil

While less mainstream compared to other nut oils, walnut oil stands out for its subtle nutty essence, making it an excellent choice for enhancing the flavors of cold dishes and salad dressings. Renowned for its high Omega-3 fatty acid content, it offers notable health benefits, particularly for heart and brain health. However, it’s important to note that heating walnut oil can affect its flavor, potentially imparting a slight bitterness.
