## Sake and the Seasons
Sake brewing follows Japan's natural calendar. The brewing season (kanzukuri, winter brewing) begins in October and ends in March, and seasonal releases throughout the year connect drinkers to the agricultural and cultural rhythms of Japanese life.
## Winter: Shiboritate (New Sake)
From January through March, breweries release shiboritate (しぼりたて) — freshly pressed sake from the current season. These {{glossary:namazake}} (unpasteurized) releases are bold, lively, and sometimes slightly rough, capturing the raw energy of new sake. Shiboritate season is a celebration at every kura.
## Spring: Hana-mi Sake
Cherry blossom season (late March through April) is peak sake season. The Japanese tradition of hana-mi (flower viewing) involves gathering under cherry trees to eat, drink, and appreciate the fleeting beauty of the blossoms. Light, floral sake — especially chilled {{glossary:ginjo}} — is the perfect companion.
## Summer: Natsu-zake
Summer sake releases are designed for warm-weather refreshment. They tend to be lighter in body, crisper in acidity, and sometimes lower in alcohol. Sparkling sake, {{glossary:nigori}} on ice, and sake highballs are popular summer styles. Blue and white bottle designs evoke coolness.
## Autumn: Hiyaoroshi
September brings hiyaoroshi (ひやおろし), sake that was pasteurized once after pressing in spring, aged through summer, and released unpasteurized in autumn. Hiyaoroshi has a mellow, rounded character — the rough edges of shiboritate softened by months of maturation. It is one of the most anticipated seasonal releases.
## The Brewing Year
The Japanese brewing year (BY) runs from July 1 to June 30. A sake labeled BY2025 was brewed during the winter of 2025-2026. This calendar anchors the production cycle to the cold months when low ambient temperatures naturally assist fermentation control.
## Celebrating with Sake
Beyond seasonal releases, sake marks life's milestones. New Year (osechi and toso), weddings ({{glossary:san-san-kudo}}), shrine festivals, and business achievements all call for sake. The seasonal thread connects Japan's past to its present through every pour.
