Once opened, Horlicks should be used within four weeks for optimal flavor and quality. This is the recommendation provided by Horlicks itself and other sources.
Storage Recommendations
To maintain the best quality, store opened Horlicks in a cool, dry place away from direct sunlight.
Beyond Four Weeks
While the recommended timeframe is four weeks, the exact shelf life after opening will depend on storage conditions. Improper storage (e.g., exposure to heat, moisture, or light) can accelerate degradation and potentially affect taste and quality.
Comparing to Similar Products
Other powdered milk products, like malted milk powder, have a similar recommendation: ideally consumed within six months for best quality, but potentially lasting up to a year if stored correctly.
