I am new to this site and I hope my question is clear to everyone.
- I prepare 4 cups of black tea in the morning by bringing water and tea powder to boiling.
- Then I pour this into flask by filtering tea powder.
- Whenever I feel like drinking tea, I pour black tea from flask, add sugar and milk and heat it for 1 minute in microwave.
I noticed that tea taste is changing from fresh prepared tea to 5 hours after.
Is there anyway to keep the same taste? I don't want to prepare tea every time I want to drink.
