What Does “Wood-Pressed” Actually Mean? A Simple Explanation
But what does wood-pressed actually mean? What happens during the process? And why does it matter for what ends up in your food?
The Ancient Context
3,500 Years of Oil Pressing — A Very Brief History
The wooden ghani — called a kolhu in Hindi, chekku in Tamil, or ghana in Kannada — is one of the oldest oil-extraction tools known to mankind. Archaeological evidence places its use in India as far back as 1500 BCE, powered by bullocks walking in slow circles around a central wooden press.
Different regions developed their own variations. The large granite ghanis of South India held 35–40 kg of seeds. The smaller wooden ghanis of western India held 8–15 kg. In Karnataka — our home — the chekku press is a cultural fixture, particularly for coconut, sesame, and groundnut oil.
The concept spread from India to Afghanistan, Sri Lanka, Myanmar, and Sudan. (FAO, Traditional Ghani Oil Processing, 1997)
How a Wooden Ghani Actually Works
Seeds are loaded into the press
Whole, cleaned seeds — coconut, groundnut, sesame, mustard, flax — are loaded into a circular mortar made of hardwood. Traditionally, dense woods like tamarind, neem, or jackfruit were used for their resistance to the oils. The pestle sits inside, connected to a rotating arm.
The press turns, very slowly
The pestle rotates at just 4–7 rounds per minute — extremely slow by modern standards. As it turns, it exerts lateral pressure on the seeds, first crushing them into a paste, then pressing the oil out. At Bhavina, a low-RPM motor powers the press — same gentle speed and pressure as the traditional bullock-driven ghani.
Temperature stays naturally low — below 40°C
Because the press runs so slowly, heat from friction is minimal. The oil temperature stays well below 40°C — far below the 60–70°C at which vitamins, antioxidants, and enzymes begin to degrade. No external heat is applied. No cooling is needed. The low temperature is a natural consequence of the slow process.
Natural settling — no additives
The pressed oil settles and clarifies naturally. No chemical filtering agents, no bleaching clay, no deodorising steam. The sediment that settles is nothing but natural seed particles — a sign of authenticity, not contamination.
Bottled and done
Seeds go in. Oil comes out. No chemicals used at any stage. No heat applied. No nutritional stripping. The oil that fills the bottle is the same oil that was inside the seed — just separated.
Cold-Pressed vs Wood-Pressed vs Expeller-Pressed vs Refined
These terms are often used interchangeably, but they are not identical:
| Method | Temp. | Tools | Chemicals? | Quality |
|---|---|---|---|---|
| Wood-Pressed (Kachi Ghani) | Below 40°C | Wooden kolhu / stone ghani | None | Highest — full nutrition retained |
| Cold-Pressed (generic) | Below 49°C | Any mechanical press | None | High — depends on press speed |
| Expeller-Pressed | 70–150°C | Screw / helical press (high RPM) | None | Good — some nutrient loss from heat |
| Refined | 150–200°C+ | Industrial + solvents | Hexane, NaOH, bleaching clay | Lowest — most nutrients stripped |
What Does Wood-Pressed Oil Look, Smell & Taste Like?
If you have only ever used refined oils, wood-pressed oil will immediately feel different:
Deeper, more saturated. Groundnut oil is rich gold. Sesame oil is amber-brown. Coconut oil is soft white and may solidify in cool temperatures.
Distinctly present. A faint, pleasant nuttiness or warmth, depending on the seed. Refined oils have had their smell removed by design.
If you taste a drop, you will taste something — subtle, clean, natural. Refined oil tastes of nothing, because it has been stripped and neutralised.
A small amount at the bottom of the bottle is completely normal — natural seed particles, not contamination. Shake gently or pour carefully.
Why Bhavina Uses the Wooden Ghani
The simplest honest answer is: because it produces better oil.
The wooden ghani is slower, quieter, and yields less oil per kilogram of seed than industrial extraction. It cannot match the speed of a refined oil plant. But what it produces — oil that is chemically clean, nutritionally intact, and genuinely flavourful — cannot be replicated by any industrial shortcut.
At our facility in Kuchangi, Arakere, Tumakuru, every batch goes through this same process. Every one of our 9 edible oil varieties — coconut, groundnut, sesame, mustard, flaxseed, sunflower, almond, castor, and neem — is wood-pressed the same way. We are not reinventing tradition; we are continuing it.
