Wood Pressed vs Cold Pressed vs Refined Oil: The Honest Comparison Nobody Shows You

Buyer's Guide Meta Description: "Cold pressed" and "wood pressed" are not the same thing — and refined oil is neither. Here is an honest, detailed comparison of all three so you can make an informed choice.

Visit the cooking oil aisle in any Indian supermarket and you'll encounter dozens of labels: refined, cold pressed, wood pressed, kachi ghani, expeller pressed, virgin, extra virgin. It can feel deliberately confusing — and in many ways, it is.

Understanding the real differences between these terms is the first step to making a genuinely informed choice for your kitchen and your health.

Refined Oil: What It Actually Is

Refined oil is the default product in most Indian households — and it is also the most heavily processed.

The extraction process begins with chemical solvents (typically hexane, a petroleum derivative) that are used to strip every last drop of oil from the seed. The crude oil produced is then put through a series of treatments: degumming, neutralisation, bleaching, and deodorisation. Each step removes impurities — but also removes natural colour, flavour, and nutrients. The final product is a uniform, clear, odourless oil with a long shelf life.

Refined oil is cheap to produce at scale, consistent in appearance, and easy to market because it looks "clean." But it is nutritionally empty — and the high-heat processing involved is known to generate trans fats and free radicals.

Cold Pressed Oil: Better, But Not Traditional

Cold pressed oil represents a genuine improvement on refined oil. In this process, seeds are crushed using mechanical presses (typically stainless steel machines) at controlled low temperatures. No chemical solvents are used. The lower temperatures mean that more nutrients, antioxidants, and natural fatty acids are preserved compared to refined oil.

Cold pressed oils have become widely available in India over the past decade as awareness around healthy eating has grown. They are a legitimate, better choice than refined oils.

However, there is an important distinction to understand: "cold pressed" is a method description, and it covers a wide range — from small-batch artisan production to large-scale industrial cold pressing. Not all cold pressed oils are equal in quality. Some commercial cold pressed oils are still processed in large batches, filtered to remove natural sediment, and bottled in a way that prioritises uniformity over nutritional integrity.

Wood Pressed Oil: The Traditional Gold Standard

Wood pressed oil — kachi ghani oil in Hindi, or chekku oil in Tamil — is the oldest form of oil extraction in India. It uses a wooden ghani: a large wooden mortar into which seeds are fed and slowly crushed by a wooden pestle, traditionally rotated by bullocks and today often by a low-speed electric motor.

The key factors that distinguish wood pressing are speed and temperature. The wooden ghani rotates very slowly — the friction is minimal, the heat generated is extremely low (rarely exceeding 40°C), and the seeds are pressed in small batches. No chemicals are involved. The oil flows out raw, unfiltered (or only lightly filtered through cloth), and completely intact.

The result is an oil with:

• Full retention of Vitamin E, antioxidants, and essential fatty acids
• Natural colour and aroma (evidence that the oil hasn't been processed)
• Natural sediment at the bottom of the bottle (evidence of minimal filtration)
• A shorter shelf life (evidence that no artificial preservatives have been added)
• A higher cost per litre (because the process is slower and yield per kilo is lower)

A Direct Comparison

	Refined Oil	Cold Pressed	Wood Pressed
Extraction method	Chemical solvent + heat	Mechanical press	Traditional wooden ghani
Chemicals used	Yes (hexane)	No	No
Processing heat	Very high	Low-moderate	Very low
Nutrient retention	Very poor	Good	Excellent
Natural aroma	Removed	Partially retained	Fully retained
Sediment	None	Sometimes	Yes (natural)
Shelf life	Long (preservatives)	Moderate	Shorter (no preservatives)
Cost	Low	Moderate	Higher

What to Look For When Buying

A genuine wood-pressed oil has a few telltale signs: a distinct natural aroma, a slight natural colour, a small amount of sediment at the bottom of the bottle, and a shelf life of 6–12 months. If a bottle labelled "wood pressed" is completely clear, odourless, and has a shelf life of two years — ask questions.

At Bare Naturals, our oils are extracted using the traditional wooden ghani method in small batches. We don't bleach, deodorise, or add preservatives. What you get is the oil exactly as it comes from the seed — no more, nothing less.
