Grapeseed Oil

Grapeseed Oil: Nutrition and Culinary Guide

Grapeseed oil is extracted from the grape seeds that remain after winemaking — a byproduct of the wine industry, produced primarily in France, Italy, Spain, and increasingly in South America and North America wherever wine grapes are grown. Because it uses a byproduct of another agricultural process, grapeseed oil has a reasonable claim to sustainability and resource efficiency. The oil requires industrial solvent extraction or high-pressure pressing to extract from the small, low-oil-content seeds, making production relatively complex. Grapeseed oil has a very light, neutral flavour and a notably high smoke point (approximately 215–230°C), making it popular in professional kitchens for applications where the flavour of the oil should not intrude. It is very high in omega-6 linoleic acid (approximately 70%), which is a nutritional consideration for regular use in large quantities.

Nutritional Value and Uses

Grapeseed oil provides 884 kcal and 100 g of fat per 100 g, with 9.6 g of saturated fat. Vitamin E content is meaningful — approximately 3.9 mg per tablespoon, primarily as gamma-tocopherol. The neutral flavour and high smoke point make it popular for high-heat applications, for making flavoured infused oils, for homemade mayonnaise (the neutral flavour avoids the bitterness that olive oil can produce in an emulsion), and as a carrier for light salad dressings. For everyday high-heat cooking, rapeseed oil is nutritionally preferable due to its better omega balance at lower cost.
