Why the third month matters
The chemistry changes late. Here is what happens between day sixty and day ninety, and why bottling early costs you.
A handbook
A jar, some scraps, and three months of patience.
Eco enzyme is a simple fermented liquid you can brew at home from fruit and vegetable peels, brown sugar and water. It cleans floors, feeds plants, and gives your compost bin a rest.
One part sugar. Three parts scraps. Ten parts water.
Every recipe you will read anywhere in the world traces back to these three numbers. Weigh them, not eyeball them, and the fermentation takes care of itself.
1:3:10
1
Brown sugar
Palm sugar, molasses or raw cane. Never white refined.
3
Fruit and veg scraps
Peels, cores, ends. Skip meat, oil and cooked food.
10
Clean water
Rain, filtered or tap left to sit overnight.
Five things a finished batch will do for you.
01
Household cleaner
Dilute one to two hundred with water for floors, counters and glass. Cuts grease, leaves a faint citrus smell.
02
Plant fertiliser
One capful to a litre of water, once a fortnight. Leaves perk up within a week.
03
Drain treatment
A cup down the sink at night. Feeds the microbes that live in the pipes and eats through soap scum.
04
Laundry aid
Half a cup in the wash with your usual detergent. Especially good on kitchen towels and sports kit.
05
Garden pest spray
One to five hundred, sprayed on leaves at dusk. Aphids and mealybugs dislike the acidity.

A field trial in a Bandung kitchen
Six jars, three sugar sources, one very patient reader. The results were not what we expected.

Reading the smell of your jar
Sweet, sour, alcoholic, vinegar, wrong. A short guide to what your nose is telling you.
From a Thai research lab to a jar on your windowsill.
The recipe most people follow today was formalised in the 1980s by Dr Rosukon Poompanvong in Thailand, then carried across Southeast Asia by a network of home gardeners and Buddhist temples. The full story is stranger and more interesting than that.
