The distilleries themselves now sell imo shochu as a highball. Soda lifts the aroma off the glass instead of burying it.
Citrus acid cuts sweet potato's weight. That's why Kagoshima bars reach for grapefruit and yuzu before anything else. Bitter, bright and forgiving. Ruby or white both work; white is drier. The grapefruit sour is a real bar order in Japan, not a novelty.
One part shochu to three or four parts of the long mixer, over plenty of ice, then the accent on top. If it tastes thin, go two to three next time.

What to mix with it
Tap a family to narrow it down. Every suggestion carries its reasoning, so if the reasoning does not convince you, ignore the suggestion.
A longer wedge is a family we'd reach for sooner with this bottle, worked out from its flavours rather than tasted. It isn't a score, or a comparison with other bottles.
Cold-brewed hibiscus tea: sour, cranberry-red and floral. Acid and color in one pour.
A berry aroma with no acid under it. Hibiscus brings the acid, and the colour comes with it
The purple stays behind in the mash rather than coming over the still, so the flower is where any colour in the glass comes from, and its acid brightens the fruit instead of fighting it
The sweetness here is aroma rather than sugar, because sugar does not come over a still. Acid is what keeps the impression from turning cloying.
Fruit without acid goes flat fast. A squeeze of something sour is what keeps a fruity bottle tasting fresh instead of sweet.
Bitter orange: sour and aromatic rather than sweet, the citrus that goes into ponzu. Bottled juice is sold for cooking and works straight in a glass. Use the peel too, it carries most of the smell.
Daidai is the citrus in ponzu, and ponzu is already on the table next to imo shochu

A Miyazaki citrus eaten with the white pith left on, which is sweet rather than bitter. Gentler and more floral than lemon, so it flavours a drink without taking it over.
Hyuganatsu is Miyazaki's citrus and imo shochu is what Miyazaki pours it beside; the soft acid does the same work on a sweet potato bottle from anywhere

Juice and peel are two different tools. Fresh juice, never bottled, is the whole basis of the lemon sour and the quickest way to put acid into a distilled base. The peel expressed over the top gives the oil and no acid at all, which is what a sweet or roasted bottle usually wants instead.

Oita's citrus, softer than sudachi. Bartenders in Oita mix it with the local barley shochu and soda.

Harder to find outside Japan than most of this list. Worth ordering or a trip to a Japanese grocery, and where something easier works as well, that comes first.
Okinawa's own citrus, picked green and sharp, more bitter than lime and more floral than sudachi. Squeezed over awamori and soda it is what the islands actually drink.

A small green citrus from Tokushima, sharper and more herbal than lime. Sold frozen or as juice in Japanese markets.

Food-grade citric and malic powder from the canning aisle, 10 grams whisked into 100 grams of cold water; two parts citric to one malic is close to lime. Some bartenders find a drink with no juice in it thin, so it is worth trying both ways.
Half an ounce of lemon juice paints over a peach note; this does not

Hoppy Beverage Co. has made it in Tokyo since 1948; at 0.8 percent it is legally a soft drink, and it is hard to find outside Japan. Chill the bottle, the shochu and the mug and no ice is needed.
The distilleries themselves now sell imo shochu as a highball. Soda lifts the aroma off the glass instead of burying it.
Carbonation carries aroma up out of the glass, so a highball shows an aromatic bottle off rather than diluting the point of it.
Eden Foods sells it as Ume Plum Vinegar in most US supermarkets, and it is one of the cheapest things on this list. A bar spoon, and unlike a crushed umeboshi it can go into a shaken drink.

Salt is the fastest way to make an earthy bottle taste like more of itself.

Hot water in the glass first, spirit poured on top so it mixes itself. Around 40C in the glass is the sweet spot. This is not the only way, it is one way.
Hot water is the Kagoshima serve and it earns its reputation: heat pulls the earth and the sweetness up out of the glass. Cold water does the opposite and lengthens it without changing its shape.
Oyuwari: hot water first, then shochu, six of shochu to four of water. Imo shochu opens up in warmth
Soft water, cold, over ice or not. One to one is normal. Mix a day ahead (maewari) and the edges round off.

Sakamoto's, fermented outdoors in earthenware jars in Fukuyama and aged at least a year; Toiro and Japanese Taste ship it in the US. A teaspoon in a mizuwari is the whole intervention, and a second one is usually a mistake.

An earthy bottle has a savoury side already, and these meet it rather than trying to sweeten it away.

Cocchi Americano: moscato steeped with cinchona bark, gentian and bitter orange. The bark is the point of it, and it carries a quinine bitterness no citrus will give you.
It brings acid and grape sugar, two things a pot still leaves behind

Braulio, made in Bormio from gentian, juniper, peppermint and yarrow, around forty-five dollars. A summer drink on shochu and a winter one on whisky, which is one bottle behaving two ways.

D.O.M. Bénédictine, on most back bars. Rounder and much sweeter than the alpine liqueurs, so it suits bottles that already lean sweet rather than clean.
Honey and saffron landing on a bottle that already smells of honey
The Japanese Bitters, five 100ml expressions, sold at Astor Wines in New York. Angostura at nearly 45 percent is a small spike in a 25 percent drink in a way these are not.

Sweet, low-acid Japanese mandarin. Juice it or drop segments in a glass. It needs a squeeze of something sharper alongside.
Kagoshima bartenders pair imo shochu with mikan when it is in season
This bottle already reads sweet, on aroma rather than on sugar. Adding real sugar to it is the most common way a drink built on it goes wrong.

Dewazakura's from Yamagata plums, or Machida Shuzo's on Amami kokuto shochu. It does umeshu's job and leaves the glass drier, which matters when the bottle is already sweet.
The bottle already smells of berry, and this puts more of it in the glass.

Ayagiku's, on a shochu base, or Kikusui's. Quince is too hard and astringent to eat raw, so the liqueur is the convenient way to get that scent into a glass; it opens up in hot water.
Karin is honey with a faint drying grip behind it, which is what keeps it from cloying

A pinch of ground sansho over the top, or a few peppercorns steeped. Numbing, citrusy, green.

The Korean-style yuzu preserve sold in jars. A spoon in hot water with shochu, or shaken cold.

The non-alcoholic koji drink, sweet from rice starch alone. Blend with the spirit and ice; it is a shochu smoothie.
Amazake softens imo shochu into a winter dessert
This mixer is sweetened too, so it lengthens the drink without cutting the sweetness that is already there.

Ways to serve it
On the rocks
Mizuwari (with water)
Sweet potato shochu is the one people are told they have to drink with hot water. Hot water is genuinely good, and it is also the hardest first sip to sell. Start it long and cold with soda and a wedge of grapefruit, and come back to the hot water once you like the spirit.
Cocktails other people made
We haven't found a cocktail written for this exact bottle. These were written for other bottles, so each one says which, and what changes if you pour this instead.
Written for Satsuma Kuradashi Genshu Shochu, also a sweet potato shochu. This bottle is lighter, 25% against 37%, so cut the mixer back or it will disappear.
If a recipe calls for something else and this is what you have. The verdict is for this bottle rather than for its style, so a bottle without the strength a stirred drink needs is not offered for one.
