Komasa Migaki Shochu, long, with Ginger beer, and Cinnamon.
The distilleries themselves now sell imo shochu as a highball. Soda lifts the aroma off the glass instead of burying it.
One part shochu to three or four parts mixer, plenty of ice. If it tastes thin, go two to three next time. That is the whole method.
What it tastes like
Imo shochu from Komasa Jyozo in Kagoshima. Importer's tasting notes: whisky like. Nobody here has tasted this one, so the profile below is estimated from what its importer publishes rather than from the glass.

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.
Ginger beer
Strong match
A spicy one, not a sweet one. The mule format works for every dark shochu and most sake.
Lemon soda (ramune, Sanpellegrino)
Strong match
The shortcut to a sour when there is no fresh lemon. Less sweet is better.
Soda water
Strong match
Cold, and fizzy enough to matter. One part spirit to three or four parts soda for shochu; one to one for sake.
Tonic water
Strong match
A dry tonic (Fever-Tree, Q). One part spirit, three parts tonic, a citrus wedge.
Amaro
Strong match
Montenegro, Nonino, Averna. Equal parts with a dark shochu over ice is a whole drink.
Aromatic bitters
Strong match
Angostura or a Japanese aromatic. Two dashes.
Cinnamon
Strong match
A stick in hot water with the spirit, or a light syrup. Winter.
Black tea (Earl Grey)
Strong match
Cold-brewed Earl Grey brings bergamot; plain black tea brings tannin. For the aged and brown-sugar bottles.
Green tea (sencha)
Strong match
Cold-brewed sencha, unsweetened. The green tea highball is one of the most common ways shochu is actually drunk in Japan.
Oolong tea
Strong match
Unsweetened, cold. One part shochu to three or four parts tea, over ice. It is the drink half of Japan orders with dinner.
Ginger ale
Strong match
The gentle ginger. For bottles that a ginger beer would bully.
Kombucha
Strong match
A plain or ginger kombucha. It brings acid, bubbles and funk, all things sake is short of.
Sparkling wine (brut)
Good match
Dry cava or crémant. Topping sake with it adds the acid and the bubbles sake lacks in one pour.
Ginger
Good match
Fresh juice, a syrup, or a good ginger beer. The spice that makes a low-proof drink feel like it has a backbone.
Grapefruit
Good match
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.
Hot water (oyuwari)
Good match
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.
Mikan (satsuma)
Good match
Sweet, low-acid Japanese mandarin. Juice it or drop segments in a glass. It needs a squeeze of something sharper alongside.
Cold water (mizuwari)
Good match
Soft water, cold, over ice or not. One to one is normal. Mix a day ahead (maewari) and the edges round off.
Vanilla
Good match
A split bean in a syrup, or a good extract, in small amounts.
Yuzu
Good match
The Japanese citrus that tastes like grapefruit, mandarin and lemon at once, with a floral peel. A little zest or juice goes a long way.
Jasmine tea
Good match
Cold-brewed. Floral without sugar. The jasmine highball is a real menu item in Japan.
Matcha
Good match
Whisked into a slurry first, never dumped in dry. Bitter, umami and creamy at once.
Banana
Good match
Ripe banana, muddled or as a syrup. The banana note in ginjo sake is real chemistry, not a metaphor.
Blackberry
Good match
Late summer fruit with a savory edge. For the deeper bottles.
Kokuto (brown sugar) syrup
Good match
Okinawan or Amami kokuto dissolved one to one in water. Molasses, minerals, a little salt.
Maple syrup
Good match
Dark, in small amounts, for the cask and sweet-potato bottles.
Passion fruit
Good match
The most useful tropical fruit for mixing: intensely aromatic and properly sour. Pulp with seeds, or a good puree.
Sea salt
Good match
A pinch in the glass or a half rim. Salt does not make a drink salty in small amounts; it makes it taste more like itself.
Umeboshi
Good match
One salted plum, crushed with a spoon in the glass. Salty, sour, savory.
Red aperitivo bitter (Campari-style)
Good match
Campari, Aperol, or a Japanese bitter like Kina. The aperitivo hour is where sake and shochu make the most sense as cocktails.
Black pepper
Good match
A few grinds over the top. Aroma more than heat.
Blood orange
Good match
Orange with a raspberry edge. Winter fruit; worth waiting for.
Cardamom
Good match
A few crushed pods, or a syrup. Floral, citrusy and warm at once; it bridges fruit and spice.
Fernet
Good match
A quarter ounce. Menthol and bitterness, for the darkest bottles.
Gentian (Suze-style)
Good match
Suze or Salers. Bitter root, bright yellow. A little in a highball changes everything.
Kabosu
Good match
Oita's citrus, softer than sudachi. Bartenders in Oita mix it with the local barley shochu and soda.
Kumquat
Good match
Eaten whole, peel and all. Muddle a few in a glass; the peel gives bitterness, the flesh gives tartness.
Lemon
Good match
Fresh juice, never bottled. The building block of the lemon sour, and the fastest way to give sake the acidity it does not have on its own.
Lime
Good match
Sharper and greener than lemon. The citrus for anything built on brown sugar or tropical fruit.
Orange
Good match
Fresh orange juice for a sparkling sake mimosa; the peel for stirred drinks with aged bottles.
Sansho pepper
Good match
A pinch of ground sansho over the top, or a few peppercorns steeped. Numbing, citrusy, green.
Star anise
Good match
One star, steeped, for the dark bottles.
Sudachi
Good match
A small green citrus from Tokushima, sharper and more herbal than lime. Sold frozen or as juice in Japanese markets.
Togarashi (chili)
Good match
A rim of shichimi, or a slice of fresh chili. Heat on fruit, not on rice.
Wasabi
Good match
A rice-grain amount, dissolved. For the savory, cucumber glass, not the fruit one.
Coffee (cold brew)
Good match
Cold brew, unsweetened. For barley, brown-sugar, cask-aged and awamori bottles; it will bury a daiginjo.
Hojicha
Good match
Cold-brewed or hot. Roasted green tea, low in bitterness, high in toast. The oyuwari of teas.
Mugicha (barley tea)
Good match
Cold, unsweetened barley tea. Every Japanese fridge has a pitcher in summer. Mix one to three over ice.
Amazake (sweet koji rice)
Good match
The non-alcoholic koji drink, sweet from rice starch alone. Blend with the spirit and ice; it is a shochu smoothie.
Calpico (cultured milk)
Good match
The concentrate, diluted with soda. Yogurt-sweet and sour. The Calpis sour is a national drink in Japan.
Jasmine
Good match
A syrup or a few dried blossoms steeped. See jasmine tea for the long drink.
Osmanthus (kinmokusei)
Good match
Dried osmanthus flowers steeped, or the syrup. Apricot and honey, and the smell of October in Japan.
Cherry
Worth trying
Fresh in early summer; morello or amarena in syrup otherwise. Dark cherry for aged bottles, bright cherry for sparkling.
Coconut
Worth trying
Coconut water for lengthening, coconut milk or cream for weight.
Kiwi
Worth trying
Muddled with the seeds. Green, sour and refreshing, and cheap year round.
Kombu
Worth trying
A small piece steeped in the bottle overnight. Savory depth without salt.
Lychee
Worth trying
Fresh in early summer, canned in syrup the rest of the year (drain it). The signature aroma of a whole school of imo shochu.
Mango
Worth trying
Ripe mango puree. Needs lime beside it or it goes flat.
Olive brine
Worth trying
A bar spoon, no more. Salt, and the savory note that comes with it.
Pickled ginger (gari)
Worth trying
A spoon of the brine, and a slice as garnish. Sweet, sour and hot at once.
Pineapple
Worth trying
Fresh juice, or grilled wedges for a smokier drink. The awamori fruit.
Shiitake
Worth trying
A dried shiitake steeped in the spirit for a day. Savory and strange in the best way.
Toasted sesame
Worth trying
A sesame syrup, or a rim of ground sesame and salt. Toasty and rich.
Ume (Japanese plum)
Worth trying
Umeboshi (salt-pickled), ume syrup, or the fruit's own liqueur. Sour, salty and savory at once.
Umeshu
Worth trying
Sweet, sour, almondy. A splash does the work of both syrup and citrus.
Yuzu marmalade (yuja-cha)
Worth trying
The Korean-style yuzu preserve sold in jars. A spoon in hot water with shochu, or shaken cold.
Genmaicha
Worth trying
Green tea with popped, toasted rice. Cold-brew it. Comfort in a glass.
Chamomile
Worth trying
Cold-brewed chamomile as a lengthener, or steeped in the spirit.
Cream
Worth trying
Half-and-half or heavy cream, in the after-dinner glass only.
Egg white
Worth trying
One white, dry-shaken. Texture without flavor.
Elderflower
Worth trying
Cordial or the liqueur. Muscat, lychee and honey in one flower.
Hibiscus
Worth trying
Cold-brewed hibiscus tea: sour, cranberry-red and floral. Acid and color in one pour.
Milk
Worth trying
Cold whole milk. Shochu milk-wari is a real order in Kyushu, not a dare.
Oat milk
Worth trying
The dairy-free milk that tastes of cereal, which is why it likes grain spirits.
Rose
Worth trying
A drop of rose water, or a rose syrup. A drop; it takes over.
Sakura (cherry blossom)
Worth trying
Salt-pickled blossoms (rinsed) or sakura syrup. Floral, faintly almond, a touch of salt.
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
Nobody has published 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, 24% against 37%, so cut the mixer back or it will disappear.
