Calpis Lacto Soda Original (Low Sugar): Sweet, Bubbly Japanese Cultured Milk Refreshment
In the chilled soda aisles of 7-Eleven Thailand, white-and-blue polka dot cans instantly point to one iconic Japanese staple: Calpis Lacto Soda Original Low Sugar (คาลพิส แลคโตะ โซดา รสออริจินัล สูตรน้ำตาลน้อยกว่า). Produced under license in Thailand, this slim aluminum can combines the tangy, cultured taste of fermented skim milk (Lactobacillus) with sparkling carbonated water.
Formulated under Thailand’s “Healthier Choice” logo guidelines, this updated version features a Less Sugar Formula containing just 11 grams of sugar and 50 calories per can. It targets soda lovers seeking a sweet, fizzy treat infused with beneficial cultured milk notes. While its unique sweet-and-sour profile has built a massive cult following across Asia, carbonated cultured dairy can lead to mixed reactions among international palates.

Taste Test & Texture Analysis
We are awarding Calpis Lacto Soda a score of 4.4 out of 5, trusting Sebastián’s glowing recommendation for this sweet, fizzy pick.
- Sebastián’s Verdict (4.4/5): The primary selling point here is sheer refreshment. Served ice-cold from the 7-Eleven fridge, the combination of sweet yogurt notes and sharp carbonation cuts through tropical heat instantly. The sweetness is satisfying without feeling syrupy, making it a go-to afternoon drink.
- The Atypical Fermented Note: From a personal standpoint, Calpis carries a very distinct flavor profile. Because it relies on fermented milk solids mixed with citric acid and carbonation, it exhibits a slightly artificial, tangy “yogurt soda” taste that can take some getting used to if you expect a standard lemon-lime or fruit soda.
- Lighter Carbonated Feel: The low-sugar formulation keeps the liquid light and crisp on the tongue, allowing the sharp bubbles to wash over the palate cleanly without leaving a heavy coat.
