Awamori
Rice wine, black yeast and memories of the archipelago
Okinawan spirit wine
Awamori is distilled alcohol oldest in Japan — born from Thai rice, black koji mold and more than six centuries of maritime trade of the Ryukyu kingdom.
The article goes from Siamese origins, three unique ingredients, the "all koji - single distillation" process, the art of brewing kusu, how to enjoy, to the survival challenge and revival efforts today.
Japan's oldest distilled liquor
Awamori (泡盛) is a specialty distilled liquor of Okinawa, considered “senior” of shochu and is Japan's oldest distilled liquor.
The formula has remained almost unchanged for more than 500 years: Thai long grain indica rice sprinkled black koji mold, fermented with water and yeast, then passed through a single distillation. The finished product is sugar-free, gluten-free, and additive-free.
“Shima-zake” — island wine
Okinawans also call it awamori shima-zake (島酒, “island wine”) or simply shima. There are many theories about the name “awamori”: awa = foam, mori = to rise — evokes the effervescence of fermentation, or the ancient way of measuring alcohol by the amount of foam that rises when pouring.
From Siam to the Ryukyu Dynasty
The awamori story is inseparable from Okinawa's commercial history. Its roots are Thai wine lao khao, according to distillation techniques landed from the kingdom of Ayutthaya (Siam).
15th century · Distillation technique arrives
Through trade with Siam, distillation techniques reached Ryukyu — then a transit hub between Southeast Asia, China and Japan. The Ryukyu adapted it to the tropical climate and used native black koji.
1671 · The name “awamori”
The word “awamori” first appeared in the list of offerings given to an Edo shogunate general — indicating that it was a valuable gift.
17th century · Royal monopoly
The Ryukyu government strictly controls: only a few families are allowed to distill. Awamori is for the upper class and given as gifts to China and Japan. Shuri — the capital with plenty of clean water — is a manufacturing center.
1879 · Ryukyu dissolved
The kingdom was annexed by Japan, the monopoly on the production and sale of awamori ended; The profession spread to the people.
1945 · World War II disaster
The Battle of Okinawa destroyed almost all distilleries; In many kusu over 100 years, both black koji and precious yeast strains were lost. Luckily, a sample of “Usaki” koji stored at the University of Tokyo was found and revived.
After the war · Reconstruction
The awamori industry gradually recovered and thrived again in Okinawa and throughout Japan. November 1 is chosen as "Awamori Day".
How is Awamori different from shochu and sake?
It's easy to confuse, but awamori has basic differences in ingredients, yeast and processing:
| Criteria | Awamori | Shochu | Sake (Nihonshu) |
|---|---|---|---|
| How to do it | Distillation | Distillation | Fermentation (no distillation) |
| Raw materials | Thai indica rice (long grain) | Sweet potatoes, barley, japonica rice… | japonica rice |
| Koji | Black koji thread; compost whole rice into koji | White/black/yellow koji, only partially | Usually yellow koji |
| Fermentation | One step (all-koji) | Two steps | Parallel multiple steps |
| Concentration | ~25–43% (some 60%) | ~20–25% | ~13–17% |
Key: black koji + single distillation
Awamori uses it Whole rice makes koji (all-koji) and Distilled once — the point that makes it richer and richer in flavor. It also existed about 100 years before shochu, and is considered the origin of shochu.
The art of making · Three ingredients, one distillation
Amazingly simple in ingredients, yet sophisticated in every step of fermentation and distillation.
Just three things — but they have to be right
Thai indica rice
Long-grain rice (thai-mai), loose and spongy, is suitable for fermenting whole grain koji. Traces of the Ryukyu-Siam trade relationship still remain today.
Black koji
Aspergillus luchuensis native. Many births citric acid — moromi has strong acidic properties and inhibits harmful bacteria in hot climates.
Water & yeast
Clean water (Shuri is famous for its water) and yeast complete the trio. No sugar, no additives.
Why black koji is "the silent hero"
In subtropical regions, batches are very susceptible to bacterial contamination. The citric acid produced by black koji creates an acidic environment, protecting the fermentation process — thanks to which awamori can make all year round even in the middle of hot season.
“Full koji – single distillation”
The most distinctive feature: all rice is turned into koji (no sub-batching), then distilled only once.
Granary & rice steamer
Indica rice is cleaned, soaked in water and then steamed.
Transplant black koji
Sprinkle black koji mold on the rice, ferment until the entire rice is formed koji — produces enzymes and citric acid.
Fermentation (moromi)
Add water and yeast, brew into moromi batches. Enzymes convert starch to sugar, then yeast converts sugar to alcohol — all in one step.
Single distillation
Distillation only once in a steamer, preserving the flavor and personality of the batch.
Filter & brew
Filter and leave to ferment in a tub or jar. The longer it is brewed, the smoother it becomes — paving the way for “kusu”.
Distilled once, full personality
Unlike wine that is distilled multiple times, which produces "neutral" alcohol, single distillation retains the oils, proteins, and aromatic compounds from koji-filled rice — creating the nutty, fatty flavor typical of awamori.
The art of composting — the older it gets, the more valuable it is
Kusu 古酒 — “old wine”
Kusu is brewed awamori 3 years or more. The longer it is brewed, the sweeter the flavor, the smoother the taste and the higher the value. Okinawans call brewing wine "letting it sleep".
Kusu is as good as or better than cognac. Baron Sho Jun — son of the last Ryukyu king — once described kusu as having "three unique smells": hair wax, ripe myrtle and... billy goat.
Shitsugi — traditional brewing system
During the Ryukyu period, each house arranged many jars (kame) awamori along the wall: wine jars oldest Placed near the door, the following jars gradually become younger. When pouring from the oldest jar, people compensate with wine from the younger jar - the mechanism is very similar solera of brandy/sherry.
Incubate in jars (kame)
Terracotta jars create a characteristic scent. But open jars can cause alcohol to evaporate: 44% can drop to 20% over time if there is a leak — so keeping the jar base is important.
Incubate in steel tank
Stainless steel tanks provide easy heat control, large capacity, and clean and pure taste — accounting for the majority of modern production.
The hundred-year-old kusu jars have been lost
Before 1945, many families kept kusu for more than 100 years. The Battle of Okinawa destroyed almost all of the ancient kusu stock — we will never know what 100-year-old awamori really tastes like. Kusu's 20–30 years of work after the war are now a treasure.
So strong that... it burns
Traditional awamori is stronger than sake and shochu — usually 25–43% alcohol, on par with vodka or whiskey. Please drink in moderation!
Hanazake (Yonaguni)
Yonaguni Island specialty, concentration up to 60% — strong enough to catch fire. The name “hana” (flower) evokes effervescent foam like flowers blooming when measuring high alcohol content.
Habushu — snake wine
Awamori soaked in herbs, honey and even a snake habu native poison - a "unique" wine for people with sticks.
Newbie version
Recently, many varieties have reduced concentration or added fruit flavors — shikuwasa (Okinawan lemon), passion fruit, apricot — aimed at young people and the export market, much easier to drink.
Enjoy & be present
A true Okinawan cup of awamori — and the survival story of an ancient profession.
Drink awamori like the Okinawans
The most common way is mixing water and ice (mizuwari). At Okinawa restaurants, awamori almost always comes with a bucket of ice and a pitcher of water.
Mizuwari
Mix water + ice — familiar ratio ~ 40% alcohol : 60% water, softens the harshness.
On the rocks
Only with ice — suitable for young, fresh awamori.
Pure (neat)
The best way to taste kusu — maybe add a little water or a small ice cube.
Highball/cocktail
Mix soda or make cocktails — a direction that is being promoted to young people.
Kara-kara & “very Okinawan” ways
Traditional awamori is poured from kara-kara — a small earthen pot with an earthen ball inside that makes a “kara-kara” sound to indicate that it is about to run out. One go. go = 0.18 liters. Local people added koregusu (awamori pickled chili) into dishes, or mixed with... milk coffee!
~47 distilleries, hundred faces
Okinawa has approx 47–48 distillers same alliance, spread over the main islands, Kumejima, Miyakojima, Ishigaki and Yonaguni. Each region and each oven produces awamori with its own personality.
Typical brand
Zuisen, Kumesen, Mizuho, Helios, Chuko, Taragawa... From traditional handmade furnaces to modern furnaces.
“Ryukyu Awamori”
As a geographical indication (GI): awamori produced in Okinawa is given this name.
Tour & tasting
Many furnaces offer distillation tours and kusu tastings. AWAMORI KAN (Shuri) has more than 1,000 types from 200+ brands.
A legacy is finding its way to life
The awamori industry faces common difficulties in Japan: aging population, shrinking market. Factory output has been decreased for many consecutive years, at one point fell to its lowest level since 1983.
Why decline?
Young people are less interested in traditional spirits; population decline; Competition from beer, whiskey highballs, soft drinks. In addition, kusu needs to be incubated for many years to recover capital - a financial burden for the producer.
Attempts to revive
Going global and innovating: branding RYUKYU 1429 (Blueship, 2016) cooperates with 3 large ovens, exports to Europe since 2019, focuses on cocktails and cooperates with famous bartenders to spread awamori.
The bottom line
Awamori is distilled alcohol oldest in Japan, made from Thai rice + black koji, according to the way All koji – single distillation, the more it is brewed (kusu), the more valuable it is. It is the epitome of Ryukyu trade — and is finding a new place in the modern cocktail world.
One glass of wine, six centuries of history
Point to remember
- The oldest: Japan's oldest distilled liquor, predecessor of shochu.
- Raw materials: Thai indica rice + black koji + water/yeast.
- Process: all koji, single distillate, sugar/gluten free.
- Kusu: aged 3+ years; solera style shitsugi in jars.
- Concentration: 25–43%; Hanazake up to 60%.
One line summary
Awamori wraps six centuries of Ryukyu trade in a glass of wine: Thai rice, black koji, single distillation and the art of brewing kusu — the longer it “sleeps,” the sweeter it gets.
