Is grape seed oil suitable for high-heat cooking, or should I only use it cold?

Cold-pressed, unrefined grape seed oil—like ALTAI SPECIALIST ORIGINAL ALTAY—is not the best choice for high-heat cooking such as frying, roasting or sautéing at high temperatures. The reason is that unrefined oils retain more of their natural plant compounds and have a lower smoke point than refined versions. When heated beyond that point, the oil can start to break down, producing an unpleasant smell and potentially forming compounds you would rather avoid in your food. The mild, neutral character that makes this oil pleasant in dressings also means it is more delicate under heat.

Instead, use grape seed oil where no cooking heat is involved, or add it at the end of cooking. It works well in salad dressings, cold sauces, dips, and drizzled over finished vegetable dishes, grains or soups just before serving. This way you get the light texture and clean taste without any risk of degradation. If you do want to cook with gentle heat—such as a brief, low-temperature sauté—keep the temperature moderate and the cooking time short, but for anything more intense, choose a refined oil with a higher smoke point, such as refined rapeseed or sunflower oil.

The same gentle handling applies if you keep the oil for skin or hair use: external application does not involve heat, so there is no concern there. The key takeaway is that cold-pressed oils are at their best when used cold or warm, not hot. This preserves both their flavour in food and their quality as a beauty ingredient.
