How to Infuse Fruits in Your Thermos Bottle

Fruit-infused water is a healthy alternative to sugary drinks. The stainless steel infusion rod keeps fruit contained while flavours release naturally. Remove the infusion rod from the bottle. Slice your chosen fruits - citrus, berries, cucumber, or mint. Pack the fruit into the infusion rod.

1. Remove the infusion rod from the bottle.
2. Slice your chosen fruits - citrus, berries, cucumber, or mint.
3. Pack the fruit into the infusion rod. Do not overstuff.
4. Place the rod back in the bottle and fill with cold water.
5. Seal with the lid and refrigerate for 2-4 hours.
6. Refill the water 2-3 times before replacing the fruit.

Tip: Gently muddle the fruit before placing it in the rod for stronger flavour. Berries and citrus release flavour faster than harder fruits.

Brewing Green Tea in Your Thermos

Green tea has been valued for centuries for its health benefits, but brewing it correctly makes a significant difference in taste. Over-steeping or using boiling water produces a bitter cup. Boil water and let it cool for 2-3 minutes until approximately 80 degrees Celsius. Place a green tea bag inside the thermos bottle.

How Do You Clean and Maintain It?

Daily: Rinse with warm water after every use. Use a bottle brush. Weekly: Fill with warm water and a teaspoon of baking soda for 30 minutes, then scrub and rinse. Avoid bleach and chlorine cleaners - they damage stainless steel. Dry with the lid off to prevent moisture buildup and odours.
