Sake (日本酒, nihonshu) is the national drink of Japan and one of the world’s most complex fermented beverages. It is also among the most misunderstood — most people’s first experience is cheap warm sake in a mediocre restaurant, which is approximately as representative of the category as instant coffee is of specialty coffee.
How Sake Is Made
Sake is made from rice, water, koji mould (Aspergillus oryzae, the same mould used to ferment soy sauce and miso), yeast, and sometimes distilled alcohol. The key process step that differentiates sake from other drinks: multiple parallel fermentation (MPF) — in a single tank, koji converts starch to sugar at the same time that yeast converts sugar to alcohol. This produces alcohol levels (15–20%) much higher than wine (11–14%) from a single fermentation. The rice used is sake rice (sakamai), larger-grained varieties developed specifically for brewing. The most important processing step affecting quality: polishing (seimaibuai, 精米歩合). The outer layers of rice contain proteins and fats that, if left in, create rougher flavours. Highly polished rice (70%+ removed, leaving only the central starch-rich core) produces more delicate, refined sake. The polishing ratio is the primary quality classification: Junmai Daiginjo (50% or less of original grain remaining) > Junmai Ginjo (60% or less) > Junmai (70% or less, no added alcohol) > Honjozo (70%, small amount of distilled alcohol added — for aroma, not to bulk out the product).
The Major Styles
Junmai (純米): pure rice sake, no added alcohol, full-bodied, rich, often slightly acidic — pairs well with food. Ginjo (吟醸): fruity, light, aromatic — often served chilled, drinks almost like a white wine. Daiginjo (大吟醸): the top of the quality pyramid, highly refined, delicate, often with melon, pear, or apple aromas. Nigori (濁り): unfiltered sake — cloudy white, sweeter, with more rice texture. Good for dessert or as an introduction for people who find clear sake too dry. Umeshu: technically not sake but a plum liqueur made by infusing ume plums in shochu or sake — sweet, approachable. Aged sake (古酒, koshu): amber-coloured, nutty, complex, oxidative — a small specialist category, similar in concept to sherry. Sparkling sake: a growing category, lower alcohol, approachable — good for people transitioning from Champagne or Prosecco.
Temperature and Serving
The temperature rule most people get backwards: premium sake (Ginjo, Daiginjo) is almost always served chilled (5–10°C) — heat destroys the delicate fruit aromas. Warming sake: appropriate for Junmai and Honjozo styles, which have enough body and flavour to survive heat and are enhanced by warmth. At a good sake bar, you will be asked what temperature you prefer. The octagonal wooden masu cup (traditional, associated with celebrations) is a ceremonial vessel, not designed for tasting — the best vessel for sake appreciation is a white wine glass, which allows you to smell the aromas. Pairing with food: sake’s natural umami (from the amino acids produced during fermentation) makes it extremely versatile with food — it pairs well with almost anything that wine struggles with (asparagus, artichokes, vinaigrette, egg yolks) and is specifically excellent with sushi, sashimi, and Japanese-seasoned dishes.
