What Is Raw Milk?

What Is Raw Milk?

Raw milk is milk that has not been pasteurised or homogenised. It comes straight from the animal — cow, goat, or sheep — after milking, and is cooled rapidly to preserve freshness. Unlike the milk you find on most supermarket shelves, raw milk has not been heated to kill bacteria, nor has its fat been mechanically broken down to prevent the cream from rising to the top.

How It Differs from Commercial Milk

Commercial milk in South Africa undergoes pasteurisation, a process where milk is heated to at least 72°C for 15 seconds (HTST) or 135°C for a few seconds (UHT). This kills harmful bacteria but also destroys some heat-sensitive enzymes, vitamins, and beneficial microorganisms. Homogenisation forces milk through fine nozzles under pressure, breaking fat globules into smaller particles so the cream stays evenly distributed.

Raw milk skips both of these steps. The result is a product that is closer to milk in its natural state — complete with a cream line at the top, a fuller flavour profile, and a different nutritional makeup.

A Brief History

For most of human history, all milk was raw milk. Pasteurisation was developed in the 1860s by Louis Pasteur and became widespread in the early 20th century as a response to poor sanitation in industrial-scale dairy production. Before refrigeration and modern hygiene practices, raw milk from large, crowded operations posed genuine health risks.

Today, the conversation has shifted. Small-scale farms with rigorous hygiene protocols, healthy herds, and modern cold-chain technology can produce raw milk that is far safer than the milk that prompted pasteurisation laws over a century ago.

Why People Choose Raw Milk

People turn to raw milk for a variety of reasons:

• Taste — Many describe raw milk as richer, creamier, and more flavourful than pasteurised alternatives.
• Nutrition — Raw milk retains enzymes like lactase and lipase, as well as heat-sensitive vitamins and beneficial bacteria that pasteurisation destroys.
• Digestibility — Some people who struggle with pasteurised milk report fewer digestive issues with raw milk, potentially due to intact enzymes and a different protein structure.
• Local food values — Buying raw milk means supporting a local farmer directly and knowing exactly where your food comes from.
• Minimal processing — In a world of ultra-processed foods, raw milk appeals to those seeking food in its most natural form.

An Honest Note

Raw milk is not without risk. Because it is not heat-treated, it can harbour harmful bacteria if not produced, handled, and stored correctly. That is why the quality of the farm, the health of the animals, and the integrity of the cold chain matter enormously.
