How Is Aleppo Soap Made? Inside the Traditional Process

Few everyday objects carry as much history as a bar of Aleppo soap. It is often called the ancestor of all hard soaps, a recipe that has barely changed in a thousand years: olive oil, oil pressed from laurel berries, water and a natural alkali, cooked in a cauldron and then left to age for years. If you have ever wondered how Aleppo soap is actually made — and whether it is something you could make at home — this is the story behind the bar.

Understanding the process is also the best way to tell a genuine, patiently made soap from a mass-produced imitation. So let us walk through it, from the cauldron to the cellar.

A soap older than most cities

Aleppo soap takes its name from the Syrian city where it was perfected, at the crossroads of the ancient trade routes. For centuries it was made only in the cooler months, when the new season's olive oil was pressed and the laurel berries had ripened. The method was passed down through families of soap makers, and the essentials have survived intact: a hot process, a hand-cut block, and a long, slow cure. It is craft, not chemistry-set convenience.

What real Aleppo soap is made of

The ingredient list is famously short. Genuine Aleppo soap contains only olive oil, laurel berry oil, water and an alkali (traditionally derived from plant ash) that turns the oils into soap. There are no synthetic fragrances, no palm oil, no colourants and no hardening agents. The green of the interior and the golden-tan of the aged crust come from the oils themselves, not from dye.

The balance between the two oils is what defines a bar. A higher share of laurel oil makes a soap richer and more prized — and more expensive, because laurel berries yield very little oil. Our Aleppo soap with 60% olive oil and 40% laurel oil sits at a generous, gentle ratio, made in the traditional way and hand-cut, with nothing added.

How Aleppo soap is made, step by step

1. Cooking the olive oil

The process begins in a large in-ground cauldron, where olive oil is heated with water and the alkali. Over the course of about three days the mixture is stirred and simmered while saponification takes place — the chemical reaction in which the oils and the alkali combine to become soap. The soap makers judge readiness by eye, touch and taste, skills learned over many years rather than from a timer.

2. Adding the laurel oil

Only at the very end is the precious laurel berry oil stirred in. Adding it late protects its character and ensures it is distributed evenly through the batch. This is the step that gives Aleppo soap its distinctive, faintly woody, herbal scent and its reputation for gentleness.

3. Pouring, spreading and levelling

The hot liquid soap is poured out onto a large, flat surface — traditionally a floor lined with paper or cloth — and spread into an even layer several centimetres thick. As it cools over a day or so, it sets into a single vast sheet of soft, green soap.

4. Cutting and stamping by hand

While the sheet is still firm but yielding, workers walk across it with cutting tools fixed to their feet or held by hand, scoring it into the familiar cubes. Each bar is then often stamped with the maker's seal. Because every bar is cut by hand, no two are exactly alike, and slight variations in weight and shape are a sign of authenticity rather than a flaw.

5. Stacking and ageing

The fresh cubes are built into loose, staggered towers so air can circulate around every surface. Then comes the part that cannot be rushed: the soap is left to cure in a well-ventilated store for anywhere from several months to several years. During this time water evaporates, the bar hardens, and the outside oxidises to that classic golden crust while the inside stays green.

Why the long ageing matters

The cure is what separates a good Aleppo soap from a harsh one. A freshly made bar is still soft and alkaline; time allows it to mellow, harden and become milder on the skin. A well-aged bar also lasts far longer in the shower, because a harder soap dissolves more slowly. This is why traditional makers speak of ageing in years, not weeks. Our bars are matured for a minimum of four years before they are offered for sale — a patience that shows in how gentle and long-lasting the finished soap is.

Can you make Aleppo soap at home?

It is a common question, and the honest answer is: you can make an olive-and-laurel soap at home, but recreating true Aleppo soap is genuinely difficult. There are three reasons to be realistic about it.

First, safety. Every from-scratch soap requires a caustic alkali (lye), which is dangerous to handle without proper equipment, ventilation and protection. It is not a casual kitchen project.

Second, the laurel oil. Good laurel berry oil is expensive and hard to source in the quantities and quality the traditional recipe calls for, which is much of what makes the authentic bar special in the first place.

Third, and most decisively, time. Even a perfectly executed batch needs many months to a few years of curing before it is mild and hard enough to use well. Most home attempts are used far too young, which is why they can feel harsh. For nearly everyone, buying a genuine, properly aged bar is simpler, safer and far more rewarding than trying to shortcut a thousand-year-old process.

How to recognise a genuine bar

Now that you know the process, the marks of authenticity make sense. Look for a green interior beneath a golden-brown crust (snap or scratch a corner to check), a short ingredient list of only olive oil, laurel oil, water and alkali, a hand-cut, slightly irregular shape, and a natural, herbal-woody scent rather than a strong perfume. A stated olive-to-laurel ratio and a real ageing time are good signs that you are holding the real thing.

Frequently asked questions

How long does it take to make Aleppo soap from start to finish?

The cooking, pouring and cutting take only a few days, but the ageing is the longest stage by far. Traditional soap is cured for at least several months, and the finest bars are matured for several years before they are sold. In total, a genuinely aged bar represents years of patience, not days.

Why is Aleppo soap with more laurel oil more expensive?

Laurel berries yield only a small amount of oil, and harvesting and pressing them is labour-intensive. The higher the laurel percentage, the more of this costly oil the bar contains, which is why a 40% laurel soap sits at a premium over lower-laurel versions. The pay-off is a softer, richer feel on the skin.

Is a harder, older bar really better?

For everyday washing, yes. A well-cured, harder bar is milder because the soap has had time to mellow, and it lasts noticeably longer in daily use because it dissolves slowly. That is exactly why traditional makers refuse to rush the curing stage.

A bar of Aleppo soap is what happens when good oils are given time and a pair of skilled hands. No shortcuts, no additives — just olive oil, laurel and patience, exactly as it has been made for a thousand years. That is the spirit we try to honour in everything we bring you at Jegit: natural, with its story intact. Pour La Vie.
