Black Soybean Tea (黒豆茶, Kuromame-cha)
Whole black soybeans, roasted until their skins split, make a clear amber tea with a roasted sweetness and no caffeine. Drink it plain, then eat the softened beans while they still hold their warmth.

Sobacha begins as grain, not leaf. That is the first small surprise. Buckwheat groats, roasted until they smell of toasted bread and warm nuts, give a tea that is clear, amber, and gentle enough for the end of the day.
There is no ceremony to fear here. The one detail that decides it is the roast. Too pale, and the cup tastes thin. Too dark, and the bitterness arrives before the fragrance. Keep the pan moving and listen with your nose: when the groats turn deep golden brown and smell round and nutty, you've done the important work.
We drink sobacha as the quiet companion to a plain meal, or after one, when green tea would be too sharp or too wakeful. It has no caffeine, no tannic bite, and nothing hidden. Just buckwheat, water, and heat handled with a little attention. Honmono is often like this, less dramatic than people expect, and better for it.
Buckwheat has long been grown in Japan's cooler upland regions, especially Shinshu in present-day Nagano, where short growing seasons made it useful when rice was less dependable. Soba became closely tied to Edo-period food culture through noodles, but roasted buckwheat tea remained a simpler household and soba-shop drink, made from the grain itself rather than from tea leaves. In modern Japan, dattan soba cha, made from Tartary buckwheat, is also common, especially where its stronger, slightly bitter flavor is prized.
The technique, the tradition, and the story behind every dish.

Equipment Needed

- •Kyūsu teapot, or any small teapot with a strainer
- •Fine-mesh strainer
Instructions
- 1
Choose the groats
Use raw hulled buckwheat groats, pale green or tan, not the dark pre-roasted kasha sold for porridge. Starting raw lets you control the roast, which is the whole flavor of the tea.
- 2
Roast the buckwheat
Put the groats in a dry skillet over medium-low heat. Shake the pan or stir constantly for 8 to 10 minutes, until the grains turn deep golden brown and smell nutty, like toasted bread. Keep the heat modest, because scorched buckwheat tastes bitter and there is no seasoning later to cover it.
Trust the aroma more than the clock. The groats should smell warm and round, never sharp or smoky. - 3
Cool briefly
Tip the roasted groats onto a plate and let them cool for a minute or two. This stops the carryover heat from darkening them further, the same small mercy you give sesame seeds after toasting.
- 4
Steep the tea
Put the roasted buckwheat in a teapot and pour over the just-boiled water. Cover and steep for 5 to 7 minutes, until the liquor is clear amber and smells toasty. Longer steeping gives more body, but after about 10 minutes the edge can turn dry.
- 5
Pour and serve
Strain into cups and serve hot. The spent groats can be steeped once more for a lighter second pot, or eaten with a pinch of salt if they are still pleasantly tender. Nothing wasted, and nothing made grander than it needs to be.
Chef Tips
- •If you can buy Japanese sobacha already roasted, use it without apology. It should smell fresh and nutty when the bag opens, not dusty or stale.
- •For a deeper cup, add another spoonful of roasted groats before you lengthen the steep. Strength from more grain tastes cleaner than strength from oversteeping.
- •Store roasted buckwheat in an airtight jar away from light. Its fragrance fades, so make only a week or two at a time if you're roasting it yourself.
Advance Preparation
- •Roast the buckwheat up to two weeks ahead and keep it in an airtight jar.
- •Brewed sobacha can be chilled and kept one day refrigerated, then served cold in summer.

Job's Tears Tea (はと麦茶, Hatomugi-cha)
Hatomugi-cha looks like a medicinal tea and drinks like roasted grain in a cup: pale, clean, faintly nutty, and easier to make than the label would have you believe.
