It's all in the rice. The nuanced world of Japanese sake and how to pair it with food

“It’s quite incredible to think of the variation in flavor sake provides, given these constraints,” says Yoko Kumano, who with Kayoko Akabori owns the shop Umami Mart in Oakland, California. The pair has written a new book, “Everyday Sake.”

She also likes to remind people that sake is a food-pairing beverage.

“It is meant to be enjoyed with food — and not just sushi,” Kumano says. Umami Mart's monthly sake club has tried pairings with cheese, pizza, French cuisine and more.

Every batch of sake — which in Japan is called nihonshu — is overseen by a toji, or master brewer, whose skill shapes the final flavor.

Here are some quick sake facts so you can sound savvy about it at a restaurant or wine store.

It begins with rice

The first step in making sake is rice polishing, or seimaibuai. Each grain's outer layers are milled away to reveal its starchy center. The more polished the rice, the lighter and more refined the sake; the less polished, the earthier the flavor. Sake also varies based on whether distilled alcohol is added and how it’s filtered, stored and served.

The two main families of sake are Junmai and Honjozo. Within those, you have grades like Ginjo and Daiginjo, reflecting how much the rice has been polished.

Grade names are on the label, though not necessarily the polishing ratio.

Junmai

Means “pure rice,” with no distilled alcohol added. These sakes range from light to full-bodied, and often have more umami and structure than other sakes. Think earthy, rice-forward flavors that pair beautifully with grilled meats or heartier dishes. Junmai is often served warmed or at room temperature, highlighting its comforting depth of flavor.

Honjozo

Contains a touch of distilled alcohol, which lightens the texture and enhances aroma without significantly changing the alcohol content. Smooth and versatile, it pairs with everything from tempura to sushi to teriyaki.

Ginjo

More delicate, made with rice polished down to 60% of its original size and fermented at lower temperatures. A bit of distilled alcohol may be added to enhance aroma. The flavor is often floral and fruity. Ginjo is best served chilled, and pairs well with lighter dishes like sashimi, sushi, salads and delicate seafood.

Daiginjo

The most extensively milled sakes, with at least 50% of the outer rice layers removed. The result is aromatic, delicate and often considered the highest-quality sake. Expect a higher price tag.

Nigori

Coarsely filtered, leaving some rice sediment (kasu) behind, giving it a milky appearance and slightly sweet, creamy texture. Its sweetness pairs especially well with spicy dishes.

Sparkling Sake

In recent years, sparkling sakes — some naturally carbonated, some artificially — have become popular as a festive touch to many occasions.

Nama

Kumano says Nama (unpasteurized sake) has been growing more popular, and appeals to people who like fresh, young beverages like Beaujolais Nouveau or fruity wheat beer. Make sure it's refrigerated both at the store and at home.

Creative additions

Hirohisa Hayashi, chef-owner and sake sommelier at Hirohisa restaurant in New York City, makes different versions of plum sake each year. He steeps Washington State-grown plums in low-alcohol sake, sometimes with shiso (a minty herb) and, this year, Okinawan brown sugar.

Serving and storage tips

Ultimately, whether sake is served warmed, chilled or at room temperature is subjective. "In general, classic dry junmai sake is often said to become softer and more approachable when (slightly) warmed. On the other hand, if you warm a fragrant daiginjo, its delicate aromas and refined character can be lost,” says Hayashi.

Sake is best consumed within a year of bottling. Store it in a cool, dark place. Once opened, refrigerate and enjoy within a week. Unpasteurized sake (nama) must be refrigerated and consumed within a few days.

Glassware

Traditional cups include small ochoko boxes, but wine glasses also work well.

Finally, take a cue from Japan: Pouring for others and refilling their glasses before they're empty is an act of hospitality and attentiveness. And don’t forget to clink glasses and say “Kanpai” (“Cheers”) before you sip.
