Awamori

泡盛あわもりawamori

Black kōji, Thai rice and the patience of the kusu jar

Awamori is a distilled spirit from Okinawa made from long-grain rice that is turned entirely into black kōji, fermented and distilled once. Aged for years in clay pots it becomes kusu, prized as one of Japan's few traditions of long-aged spirits.

Awamori is often described as Japan's oldest distilled spirit. Distilling is generally thought to have reached the Ryūkyū Kingdom through its trade with Southeast Asia, particularly Siam (Thailand), around the fifteenth century, and the practice of using long-grain rice survives from that connection. Under the kingdom, awamori was produced under royal licence in three districts of the capital Shuri and was sent as a prestigious gift to China and to the Tokugawa shogunate.

Awamori differs from other shōchū in three ways: all of the rice is made into kōji, using black kōji suited to Okinawa's warm, humid climate; there is a single fermentation without further additions; and the spirit is often aged for years. The name has several explanations, one being the foam (awa) that rises when strong spirit is poured, which was once used to judge its strength.

How awamori is made

Long-grain indica rice, mostly imported from Thailand, is washed, soaked and steamed, then cultivated entirely with black kōji. Long-grain rice is less sticky than Japanese rice, which makes it easier to grow kōji evenly on it. Black kōji produces large amounts of citric acid, which keeps the mash from spoiling in the heat. Water and yeast are added, the mash ferments for about two weeks, and it is distilled once in a pot still.

Awamori is usually bottled at 25 to 43 per cent alcohol, with 30 per cent a common standard. It is legally classified as a honkaku shōchū, but it is labelled and marketed separately, and Ryūkyū awamori is a protected geographical indication for spirits made in Okinawa by the traditional method.

    Black kōji mould, known as Aspergillus luchuensis after Ryūkyū.

  • Zen-koji shikomi

    全麹仕込みzen-kōji shikomi

    The method of turning all the rice into kōji, unique to awamori.

Kusu: aged awamori

Awamori that has been aged for at least three years is called kusu (in standard Japanese koshu). Since 2015, the label may say kusu only if the entire contents have been aged for three years or more; a stated age refers to the youngest part of a blend. Aging softens the spirit and develops sweet, vanilla-like and nutty aromas.

Traditionally, kusu is aged in large earthenware jars (kame). Families would set aside awamori at the birth of a child and open it on a later celebration. Kusu matured for a century or more once existed in old Shuri households, but nearly all of it was destroyed in the Battle of Okinawa in 1945.

  • Kusu

    古酒kūsu

    Awamori aged for three years or more.

  • Kame

    甕kame

    Earthenware jar for aging; porous clay is said to help the spirit mellow.

  • Shitsugi

    仕次ぎshitsugi

    A topping-up system in which awamori drawn from the oldest jar is replaced with slightly younger spirit, and so on down the line, keeping the oldest jar's character alive.

Drinking awamori

Awamori is commonly drunk mizuwari (diluted with water and ice) with Okinawan food such as gōyā chanpurū, rafute (braised pork belly) and tofu. Good kusu is often sipped neat in small cups (chibuguā), or with just a little water. Awamori is also the base of koregusu, a hot-pepper condiment for Okinawa soba, and of mixed drinks with local citrus such as shīkwāsā.

On Yonaguni, Japan's westernmost inhabited island, a traditional first-run spirit called hanazake is bottled at up to 60 per cent alcohol; because of its strength it is legally classed as a spirit rather than awamori.

  • Koregusu

    コーレーグースkōrēgūsu

Timeline

  1. 15th century

    Distilling reaches the Ryūkyū Kingdom, probably through trade with Siam and Southeast Asia.

  2. 17th–19th century

    Production is licensed by the royal government in three districts of Shuri; awamori is sent as tribute and gifts to China and Edo.

  3. 1879

    Ryūkyū is annexed as Okinawa Prefecture, and royal control of awamori ends.

  4. 1945

    The Battle of Okinawa destroys most distilleries and nearly all historic kusu.

  5. 1995

    Ryūkyū awamori becomes a geographical indication.

  6. 2015

    Labelling rules change: kusu must consist entirely of spirit aged three years or more.

  7. 2024

    UNESCO inscribes traditional kōji-based brewing in Japan, including awamori.

Frequently asked questions

Is awamori the same as shochu?

Legally awamori is a type of honkaku shōchū, but it has its own method: all the rice is made into black kōji, and it is often aged for years. It is made only in Okinawa.

Why is awamori made from Thai rice?

Long-grain rice is easier to cultivate evenly with kōji, and the tradition goes back to the Ryūkyū Kingdom's trade with Siam. Some distillers also make awamori from Okinawan or Japanese rice.

What is kusu?

Kusu is awamori aged for at least three years, usually in clay pots or tanks. It is smoother and sweeter than young awamori.

How strong is awamori?

Most awamori is between 25 and 43 per cent alcohol, with 30 per cent a common standard; many kusu are stronger. It is usually drunk diluted with water.
