Actually very easy

Grape molasses

The beliefPeople assume pekmez is made with added sugar, or that it needs a cauldron and a village.

The truthThe grape’s own sugar is enough. You clarify the must with earth and boil it down to a third.

Four hours

How to make it

What you need

6 kg of very ripe sweet grapes
1 tablespoon of pekmez earth, from a herbalist
Muslin

6000 g	Very ripe sweet grapes	grape
—	Pekmez earth	no record

An empty weight means that line could not be turned into grams — either the amount is open ("to taste") or the ingredient has no record here. Neither enters the sum as zero; they do not enter it at all.

Wash the grapes, pull them from their stalks and crush them by hand or in muslin to draw off the must. Do not grind the pips: their tannin makes the molasses astringent.
Slake a tablespoon of pekmez earth with a little must, stir it through the rest and leave it two hours. The liquid clears at the top while the sediment settles.
Ladle the clear layer carefully into another vessel and strain it through muslin. Do not disturb the sludge — stirred-up must leaves a dull molasses.
Simmer it uncovered in a wide pan over low heat, skimming in the first hour. It will take until the volume is down to a third — four hours is normal.
Test it: a bead on a cold plate, drawn through with a finger, should leave a track that stays open. Jar it hot and close it once cold.

Why it works

The juice of ripe grapes is 20–25% sugar, almost all of it glucose and fructose — which is to say pekmez is a sugar the body does not have to break down first, and that is why it reads as fast energy. The difficulty is acidity: tartaric acid both hardens the taste and throws sediment as it boils. Pekmez earth, a chalky clay rich in calcium carbonate, neutralises that acid and drags the suspended solids down with it; the step is a clarification rather than a seasoning. Then the water goes: reduced to a third, the sugar reaches 68–75%, water activity falls below 0.75 and the molasses preserves itself. Its dark colour owes more to Maillard than to caramelisation, as amino acids in the must react with the sugars.

The rough sum

4140 kcal in total

100% of the mass has figures behind it. This is the sum of what GOES IN rather than of what comes out. Wherever something evaporates, drains or ferments the two differ: a kilo of milk is 150 g of cheese.

Storage & shelf life

How long it keeps

Sealed jar, cool and dark: 2 years
Opened, at room temperature: 1 year
Fridge: Unnecessary — it only stiffens
If it sugars: Warm it gently and it dissolves

Pekmez has low water activity and needs no fridge; cold only makes it stiff. Sugar crystals may form at the bottom over time — not spoilage but saturated sugar settling out, and a jar stood in warm water takes them back into solution. What does matter is a wet spoon: every drop of water lowers the sugar concentration at the surface, and that is exactly where yeast starts.

When to bin it A domed lid, bubbles or foam at the surface mean fermentation has started, and an alcoholic smell confirms it. Do not try to rescue it by boiling — bin it.

History

Where it comes from

For centuries, when sugar was scarce and expensive, pekmez was Anatolia’s sweetener — and less an agricultural product than a storage technology, stretching a few weeks of harvest across a year. The fruit changes by region — grape, mulberry, carob, even watermelon — while the technique does not. Pekmez earth sounds strange today, but its function is chemically plain and it has been used for the same reason for centuries. Tahini and pekmez sharing a breakfast table is not chance either: pekmez gives iron and fast sugar, tahini fat and protein, and together they make a meal.

The knack

The riper the grapes the less boiling they need. Starting under-ripe and boiling longer gives burnt, not sweet.
Without pekmez earth, a pinch of bicarbonate neutralises some acid but does not clarify, and the molasses stays cloudy.
Stir often in the last half hour. As the sugar concentrates the risk of catching rises sharply, and one distracted minute turns the whole batch bitter.
