Experience a refreshing twist on a classic cocktail with the Japanese Lemon Sour. This delightful drink combines the crispness of shochu with the zesty brightness of fresh lemon juice, balanced perfectly with a touch of simple syrup and a splash of club soda. It's a perfect beverage for any occasion, offering a harmonious blend of sweet, sour, and effervescent flavors.
One ingredient you might not have readily available at home is shochu. This Japanese distilled spirit is similar to vodka but has a unique flavor profile that sets it apart. When heading to the supermarket, look for it in the international or liquor section. If you can't find shochu, you might consider substituting it with vodka or another clear spirit, though the flavor will be slightly different.

Ingredients For Japanese Lemon Sour Recipe
Shochu: A Japanese distilled spirit that is similar to vodka but has a unique flavor profile.
Fresh lemon juice: Provides a zesty and bright citrus flavor that is essential for the sour component of the drink.
Simple syrup: A mixture of sugar and water that adds sweetness to balance the sourness of the lemon juice.
Club soda: Adds effervescence and a refreshing quality to the cocktail.
Lemon: Used as a garnish to enhance the visual appeal and add a hint of extra citrus aroma.
Technique Tip for This Recipe
When preparing the simple syrup, ensure it is fully cooled before adding it to the cocktail shaker. This prevents the ice from melting too quickly, which can dilute the shochu and affect the overall balance of flavors in your Japanese Lemon Sour.

How to Store or Freeze This Drink
- To keep your Japanese Lemon Sour fresh and zesty, store the shochu in a cool, dark place, away from direct sunlight. This will preserve its delicate flavors.
- Freshly squeezed lemon juice can be stored in an airtight container in the refrigerator for up to 3 days. For longer storage, consider freezing the juice in ice cube trays and transferring the cubes to a freezer bag.
