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.
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
The peel is doing what the orange twist on an old fashioned does
An earthy, heavy spirit flattens out without acid. This is the ingredient doing structural work, not decoration.
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.
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
Mild enough that a light bottle is still the thing you taste

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.
Sharper and more bitter than a lime, which is what keeps it from disappearing into a light bottle

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 is what a roasted imo is built for: the heat puts the roast back in the air
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.

Mizuwari shows a clean bottle as it is, just lighter
Maewari: mix imo shochu and water a day ahead and it rounds out
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.
A vinegar with savour under it rather than only sharpness, so beside a savoury bottle it reads as family instead of contrast

An earthy bottle has a savoury side already, and these meet it rather than trying to sweeten it away.
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.
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.
An aged bottle is the one you would not lengthen with a beer substitute
One part shochu to five parts Hoppy drinks like a pint with none of beer's body. A 25 percent bottle lands just under 5; the figure follows the bottle, so a 40 percent one is nearer 7
It was built around neutral shochu, and that is still where it fits best
Cynar, 16.5 percent, which is weaker than most shochu, so equal parts with a 25 percent bottle lands near 20 and the drink stays long. Soda or a grapefruit soda over the top is the producer's own serve.
With a 25 percent bottle under it the bitterness reads as celery and walnut skin instead of being scorched off
There is enough weight here to stand up to a bitter or a spice without disappearing under it.

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.
The Umami expression is kelp, shiitake and bonito, aimed at the savoury side the bottle is described with

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.
A moscato base, so the grape in the bottle and the grape in the glass say the same thing

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.
Fresh lemon reads harsh against aged, caramel notes

The Kyushu condiment, in a tube in any Japanese grocer: fermented yuzu peel, green chili and salt. A quarter teaspoon stirred into an oyuwari, which is the serve Asahi publishes.
The salt in it raises the perceived sweetness of koji
Warm spice gives an earthy bottle a pulse without covering the earth itself.

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.
Lustau or González Byass. Fino is salt and living flor; this is what is left after the flor dies, and at 18 percent an ounce lengthens the glass rather than strengthening it.
Both have spent years going quietly brown, and they meet in the middle
Flor leaves a savoury edge behind it, and koji leaves the same one
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.

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.
With no juice in the glass a light bottle can end up tasting thin; a fuller one carries it
A clean bottle has nowhere to hide, so acid reads as brightness rather than as a correction

The cordial, sweet and alcohol-free, poured like a syrup. Muscat, lychee and honey in one flower. The liqueur has its own entry below: a different product rather than a stronger or weaker version of this one, and it brings alcohol along with the flower.
Nothing here is sharp enough to cut the elderflower down, so it survives at the strength it was poured
Elderflower tastes of muscat and lychee already
This mixer is sweetened too, so it lengthens the drink without cutting the sweetness that is already there.
Only for the lychee-scented bottles. On a heavy, roasted imo the flowers simply disappear.
A pinch of ground sansho over the top, or a few peppercorns steeped. Numbing, citrusy, green.

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
Hana Makgeolli is brewed in Greenpoint, Brooklyn; Makku sells a canned one. Strength varies widely across the category, from around 6 percent in a can to the mid teens for an unfiltered takju, so read the label before deciding how much to pour.
The yeasty haze gives back the body distillation took out
Jack Rudy's Extra Bitter, made with real cinchona bark, or Small Hand Foods'. Half a teaspoon and soda, set to the bottle in front of you rather than to a tonic maker's idea of a spirit.

Roasted buckwheat, in any Japanese grocery, hot or cold. In a soba restaurant the same serve is made with soba-yu, the starchy water the noodles were boiled in, which is thicker and cannot be bought.
This bottle's aroma is the reason to own it, and a roasted or smoky mixer covers exactly that.

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
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.
Young sansho leaves, clapped between the palms and floated. Hard to find outside Japanese markets in spring, worth the hunt.
A single leaf on a clean bottle changes the whole glass

Torn leaves steeped briefly. Perfumed citrus without juice.

The Korean-style yuzu preserve sold in jars. A spoon in hot water with shochu, or shaken cold.
Yuzu tea and imo shochu oyuwari is a Kagoshima winter
The bottle already smells of honey, and this puts more of it in the glass.
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.

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

Ways to serve it
Oyuwari (with hot water)
Straight
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.
