🥱

Drink Fatigue

Soda, juice, energy drinks, sparkling water — you have tried them all and nothing excites your palate anymore. You need something genuinely new and different.

What Makes Calpis Special

A unique fermented milk concentrate that has been perfected over a century.

🦠

Lactic Acid Bacteria

Calpis is made through lactic acid bacteria fermentation of milk. This process creates the distinctive sweet-tart flavor and provides natural probiotic benefits for your gut.

🥛

Cultured Milk Base

The foundation is fermented milk, creating a creamy yet light base. Unlike yogurt, Calpis is smooth and drinkable — the fermentation gives complexity without heaviness.

💧

Dilute to Your Taste

Calpis concentrate is designed to be mixed. Dilute with water for a light refresher, milk for creaminess, or soda for fizz. You control the strength and sweetness.

🌊

Calpis Water Magic

The seasonal Calpis Water is pre-diluted to the perfect ratio. A lighter, more refreshing version designed specifically for hot Japanese summers. A cultural phenomenon.

Calpis is manufactured by Asahi Group Holdings. The original formula has remained largely unchanged since 1919, a testament to its timeless appeal. Product information sourced from official Asahi materials.

🤍

Clean, Simple Formula

The original Calpis formula is remarkably simple: fermented milk, sugar, water. No artificial colors, no complex chemical list. A century-old recipe that just works.

100+ Years of Cultured Refreshment

Calpis was born from a simple observation: the fermented milk drinks enjoyed in Mongolia were both delicious and good for health. That inspiration became one of Japan's most beloved beverages.

1919
Calpis Is Born

Kaiun Mishima, inspired by the fermented milk beverages of Central Asia, creates Calpis in Japan. The name combines "cal" (from calcium) and "pis" (from the Sanskrit word for supreme nourishment). It is one of Japan's first commercially produced lactic acid bacteria drinks, introducing the concept of fermented milk beverages to Japanese consumers.

1950s – 1980s
Becoming a Household Name

Calpis grows from a novelty health drink into a mainstream Japanese staple. Families discover the joy of mixing the concentrate with water, milk, or soda. The sweet-tart flavor becomes synonymous with refreshment. Calpis becomes as much a part of Japanese food culture as miso soup and green tea.

1990s
Calpis Water Changes Everything

Asahi (which acquired Calpis) launches Calpis Water as a seasonal summer limited edition. It becomes an instant cultural phenomenon. Each year, Japanese consumers eagerly await its return to store shelves. The seasonal release strategy becomes one of the most successful marketing moves in Japanese beverage history.

Today
A Living Legend

Now over 100 years old, Calpis remains one of Japan's most beloved drinks. The original concentrate and seasonal Calpis Water continue to fly off shelves. Asahi has expanded the line with new flavors and formats, but the original formula endures. Calpis is now available internationally, introducing a new generation to the sweet-tart magic of cultured milk.

Pro Tips for Calpis

Get the most out of your Calpis experience with these mixing and serving tips

💧

The Perfect Ratio

For the classic Calpis taste, mix 1 part concentrate with 4-5 parts cold water. For a stronger, more tangy flavor, use less water. For Calpis milk, mix 1:3 with cold milk and add ice.

🧊

Always Serve Cold

Calpis is best enjoyed ice-cold. Add plenty of ice to your glass. The cold temperature enhances the refreshing quality and balances the sweetness. Warm Calpis is not the experience you want.

🫧

Try It Fizzy

Mix Calpis concentrate with sparkling water or soda water instead of still water. The carbonation adds an exciting dimension to the sweet-tart flavor. It is like a creamy fizzy lemonade.

🍹

Cocktail Game

Calpis + shochu (Japanese liquor) + ice = a classic Japanese izakaya drink called "Calpis-sour." You can also mix with vodka, white rum, or sparkling wine for creative cocktails.
