How should I store the JATŠMENNIJ KOLOS coffee drink powder after opening, and does it have a long shelf life?

To keep the powder dry and preserve its roasted aroma, store the opened jar or container in a cool, dark place away from direct sunlight, heat sources, and moisture. A kitchen cupboard is ideal. Ensure the lid is tightly closed after each use to prevent the powder from absorbing humidity, which can cause clumping.

As a dry, instant product made from roasted barley, it typically has a long shelf life when stored properly. Check the 'best before' date printed on the packaging for the specific timeframe. Over very long periods, the intensity of the roasted flavor may gradually diminish, so it's best used within a reasonable time after opening for optimal taste.

This is general advice for instant grain beverages. The product contains natural plant compounds and fibre from barley. It is not intended to diagnose, treat, or prevent any disease.
